Too many python installations. Should i remove them all and install the latest?

[Νικόλαος Κούρας]

I'am using CentOS v6.4 on my VPS and hence 'yum' install manager and i just tried:

Code:
root@nikos [~]# which python
/usr/bin/python
root@nikos [~]# which python3
/root/.local/lib/python2.7/bin/python3
root@nikos [~]# which python3.3
/root/.local/lib/python2.7/bin/python3.3
root@nikos [~]#

Why so many pythons in my system.
Now in the case of my Python3 installation, it looks like i have two parallel installations of Python3, but i don't. One is almost certainly a symlink to the other and not an actual installation.

I'm thinking of:

yum remove python
yum remove python3
yum remove python3.3

and

yum install python3.3.2 from scratch.

I'm sceptic about uninstalling python 2.x though. Seems to me as a bad idea because most of the core system utilities are written in Python 2.6+. Yum, for example, is a collection of Python 2.6 programs. If i actually do "yum remove python" i will see most of my core system get listed in the uninstall dependency list -- which is a Bad Thing.

But then again i dont like the idea of having too many Python into my system.
What is you opinion?

Check if python3 and python3.3 aren't the same. Run them and look at the "intro" lines.

Well is it a symlink?

What a fantastic way to completely break your os! Python 2 is is a deep
dependency of CentOS. You cannot remove it. Python3 and 3.3 can be
removed of course.

So it looks like you have two Python installations, one for Python 2
and one for Python 3. Why is that too many?

So i have
2.6
2.7

3.3

4 installations?

[Alister]

Do not "Yum Remove Python" as you suggest this will remove vital system
tools.

I have both Python 2.7 & python3 (Python 3.3) on my Fedora system with no
problems so i would not worry

If you're not using it, and if yum isn't going to remove anything else
that has it as a dependency, then go ahead.

On the other hand, there's really not much harm in leaving it. Python
2.6 is already your default Python.

Is this the same system where you recently spent a lot of time
upgrading your web scripts to Python 3?

[Ian Kelly]

Oh, I see. The python3 and python3.3 are probably the same binary, though.

In any case, since Python 2.7 and Python 3 are both installed under
/root/.local, it looks like you didn't install them using yum in the
first place. You probably installed them from source. If that's the
case, you can probably just rm -rf the python2.7 folder from each of
the /root/.local subfolders that has it.

Yes, its the same system but it reports python 4 times.
I just hate seeing this:

could you please tell me what commands i should issue?

[Νικόλαος Κούρας]

OMG i gave by mistake

root@nikos [/]# rm -rf /root/.local/

did i screwed up my remote VPS which i host 10 peoples webpages?

[Ian Kelly]

I don't know, is that where you were keeping the data?

The website still appears to be working, as best I can tell from this
computer. I've never actually been able to view it from here, because
I get a UnicodeDecodeError at this line:

host = socket.gethostbyaddr( os.environ['REMOTE_ADDR'] )[0]

But at least I'm still seeing that error, so the server is still
responding to requests.

[Νικόλαος Κούρας]

Everything seem to be workign as expected, my webiste and the other 10 client websites just chhecked.

luckily i keep my stuff at /homw/nikos so there are untouched.
i hope i havent deleted anything though system need form /root/.local but i guess this is where root's user personal stuff and instalation of python from source where. i ddidnt know if it has soemhtign else.

Couldn't you check ten websites which are your responsibility, instead of asking this list?

No. Wait. Why are you uninstalling python 2.6? Because you have too many python installations?

If you're on a production server with client data, should you really have a root shell?

Explained below, underneath each pertinent info you provided.

First, let's discuss Python 2.6:

This is the version of that CentOS 6 is using. It is Python 2.6 as
shown in the next paragraph. This version is essential to CentOS 6.
This cannot be changed or upgraded without so much work that no sane
person on the planet would bother. Stop worrying about it.

Apart from the bizarre trailing '*' characters which for which I have
no sane explanation, all of the above is standard for Python 2.6 which
is essential for Centos 6. Stop worrying about it.

Now let's talk about yum:

Your yum setup does not find python3 or python3.3 packages.
So you could not have used yum to install it.
Therefore, you cannot use yum to remove it.
And, you cannot use yum to install it.

Now let's talk about Python 2.7:

> root@nikos [~]# which python3
> /root/.local/lib/python2.7/bin/python3

There's a python2.7 directory there under /root/.local. Maybe you
installed python2.7 from source using some kind of 'make install'
command (ie not using yum)? If so, and you wish to remove it, there
will probably be another 'make' command to remove it, which must be
run from the same directory that you ran 'make install'. Try 'make
help' in that directory. Maybe someone else can explain why there is a
python3 command under that directory, because I can't.

Now let's talk about Python 3:

There's a python3 directory there under /opt. Maybe you installed
python3 from source using some kind of 'make install' command (ie not
using yum)? If so, and you wish to remove it, there will probably be
another 'make' command to remove it, which must be run from the same
directory that you ran 'make install'. Try 'make help' in that

cant remove it.

Why you say i cant just yum install python3.3.2

that way it would be installed correcttly automaticall by yum manager
and if later i want to remove ot to install 3.3.3 or a later version i
would have to do yum remove python3.3.2

but yum cant seem to find any python packages to install.

Still i feel my system is a bit messed p and i just want to leave the
2.6 installed and remove all the rest python and then yum install
the_latest_one.

I believe that indicates that his 'ls' is aliased to 'ls --classify',
which puts * after executables (and / after directories, and @ after
symlinks, also a few others). Not a problem.

It's not half as messed up as... uhh, scratch that. It's not half as

The Makefile would be located in the source directory where you built
Python, not in the installation directory. But in any case, I don't
think the Python Makefile includes an uninstall option. If you want
to uninstall Python that was built from source, you need to remove the
files by hand.

> Why you say i cant just yum install python3.3.2

Because CentOS 6 evidently does not provide a package for any version
of Python other than 2.6. If you want to install another version, you
will need to do it from source.

Probably friendlier than humans will be, considering that Ubuntu
doesn't complain about careless use of Google Groups.

Why not try making your own administrative decisions, rather than
expecting other people to validate you? Are you that short on
confidence that you need someone to say "Yes yes, you're doing the
right thing" and pat you on the back?

ChrisA

[Chris Angelico]

Yeah. I know that particular one because I have l aliased to ls -CF
(aka --columns --classify), mainly because it came that way as a
commented-out entry in my first Debian. Have since become quite
accustomed to it; to me, 'l' means 'look' (I do love my MUDs), so I'm
considering aliasing 'gl' to 'pwd' so that I can 'glance' too :)

Hmm. What other MUD commands have obvious Unix equivalents?

say --> echo
emote --> python -c
attack --> sudo rm -f

Python 2.6 is required for CentOS to function. You simply cannot remove
it. You can't replace it with 2.7 either. You can install 2.7
alongside it if you want (seems like you have).

Thats exactly my thoughts.
Can you please tell me HOW TO GET RID OF ALL PYTHON SETUPS except 2.6 that is needed for system core and then just install 3.3.2?

also why cant i install 3.3.2 using yum. if i could instead of building from source then i wouldn't have this installed mess but i could simply
yum remove python*

Nuke the hard drive from orbit. It's the only way to be sure.

That would require that the repo have a 3.3.2 build in it. I don't
know the Red Hat / CentOS policies there, but I know Debian stable
wouldn't have anything so new - it takes time to test things.

Is there a way to change to some repo that contain the latest python 3.3.2 to yo yum it?

Do you advise me to have the peple that iam paiding the VPS to switch me from CentOS 6.4 to ubuntu or even better debian?

I asked Google:

extra yum repositories for centos

and it pointed me at:

http://wiki.centos.org/AdditionalResources/Repositories

Probably one of these has Python 3. Or build it from source; it's not hard.

Should i chnage form CentoOS 6.4 to ubuntu by your opinion?

[Cameron Simpson]

No. Just sort it out on CentOS. Try the extra repos. Get Python 3
from one (I'm not sure why you think your current Python 3 install
is a problem anyway, though).

You're already slightly familiar with CentOS. Switching distros
will just cause more pain. Fix your actual problems first.

This is not a recommendation one way or another re CentOS versus
Ubunutu; it is a recommendation not to change without a better reason.

Agreed. I happen to like Debian-family Linuxes, having spent most of
my Linux time on either Ubuntu or Debian (and am now happy with Debian
Wheezy on most of my computers), but there's really no point jumping
ship randomly. I'm saying this for the archive only, though. Nikos
just needs to learn the skill of figuring out where his problems
really are.

Let me brutally blunt here, nick: have you googled for the answer or
are you just expecting us to do all your research for you?

I googled for this out of curiousity and found at least one third-party
repo that did have Python 3.3.x in it for CentOS/RHEL 6.4. I'll give
you a free hint about finding it: sometimes you have to add RHEL to the
search term as well as CentOS, since CentOS is a free clone of RHEL.

Because _you_ installed them. And we _know_ this because you've posted
multiple threads relating to your problems with _your_ installations
of Python 3. Even more entertainingly:

You seem to have installed python3 inside of a local copy of
python2.7. Awesomely professional webhosting service you're providing

Did you _really_ need to post this? Was it to have us confirm they

STOP EXPERIMENTING ON YOUR PRODUCTION SERVER. You should have a test
server that is a mirror of your production on which you can _safely_
flail around ignorantly without _costing your customers_ in lost time
or data. They're sure as hell should _not_ be paying you to learn
Python badly.

I don't use an explicit 'go' though, I usually just type 'n' to go
north, or 'booth1' to go booth1. Unfortunately that doesn't translate
well into a simple alias :)

Hey, if you like MUDs, why not come play D&D with us? minstrelhall.com

What shell do you use? Zsh supports this (implicit cd). I don't have
it active because it's not that useful - you get better completion
with explicit cd - but it exists.

Chris and others have told you how they go about solving their problems.
Quite a few times. In fact repeating themselves even. I think we've
run out of different ways to saying it now.

It's a process of research, tracing execution, understanding code flow,
beta-testing code on a local machine (not on a production server!). Why
do you expect it to be any different?

[Νικόλαος Κούρας]

Could you please install them because i need to work?

a) pip (so that i can successfully run 'pip install pymysql'
b) development tools

I wiped the while perl away (leaving intact 2.6) but i wiped out pip at the proces to.

Pip should be in your system's package manager. In Ubuntu it's available through sudo apt-get install python-pip.

What are those development tools you speak of?

Why would you uninstall perl?

Sorry i meant Python, not Perl

I'm using CentOS.

So, i guess its something like 'yum install python-pip'
i cannot find it, have searched it in variosu ways.

If you're going to claim to have tried something, can you at least
tell us what you tried? Because quelle surprise! the most obvious
combination of search terms works:

[plone@localhost]$ yum search python-pip
...
python-pip.noarch : Pip installs packages. Python3 packages. An
easy_install replacement

If you're not seeing this then you've broken your package manager,
possibly by overwriting the existing repositories with the new ones
you've added. It's next to impossible to tell, however, because we
don't have an access to what you mean by "variosu ways".

Expert tip: there's this AMAZING technology called "Google", which if
you visit their site, enter the cryptic incantation "python pip
centos", and click on *the very first link*, it actually provides you
with explicit directions! What brave new world that etc!

It is not the recommended way to install pip, but you can ironically easy_install pip

Did you even bother to google it? If you did, you'd find that
python-pip is available in a semi-official repository called EPEL. Just
about every RHEL and CentOS install should have EPEL installed. Now
it's pip for Python 2.6 of course. If you need python 3.3, there is a
repo out there (third-party of course) that google can help you find.
