Installing Enchant on Ubuntu

[ghy...@gmail.com]

Hi all, 

Relatively new to Python and Linux, so apologies in advance.. but:

Cannot seem to get Enchant running on my machine. 

I have Python 3.4.3 and Ubuntu 14.04. 

I get the following: 

Python 3.4.3 (default, Oct 14 2015, 20:33:09) 

[GCC 4.8.4] on linux

Type "copyright", "credits" or "license()" for more information.

>>> ================================ RESTART ================================

>>> import random

>>> import enchant

Traceback (most recent call last):

  File "<pyshell#1>", line 1, in <module>

    import enchant

ImportError: No module named 'enchant'

>>> 

From the command line I used the following:

sudo apt-get install libenchant1c2a

sudo python -m pip install pyenchant

I have noticed that the enchant folder sits in the python2.7-->dist-packages folder and not in the python3.4-->dist-packages. 

Not sure if that's an issue and if so, how to correct..?

Any advice appreciated :-)

oh, that explains it. There are many bad and mean people out there that
tell innocent users to use sudo to overwrite files. It's all over
internet so I'm not surprised you were misled as well...

you should never ever use sudo with tools like pip, gem, npm or anything
else that is not apt or dpkg to install system files. This will break
your system! If your want pyenchant to be installed system-wide, just
`apt-get install python3-enchant` it. If for some reason that's not
enough for you (you need different version or given module is not
packaged) - use virtualenv or install to ~/.local. Do not ever
overwrite system files - it will break your system sooner or later (been
there several times thanks to my co-workers)

Thanks Piotr!

I will give this a try and let you know how I get on. 

Regarding Linux.. yes, it is confusing when you first step into the fold. 

I've searched the web for a useful step by step guide and will continue looking. 

All I really want/need is a reasonable level of competency - if there are good resources (e-books or similar) you're aware of, would appreciate you pointing me to them!

Hi Piotr, 

So, I have just typed "apt-get install python3-enchant" at the shell. 

I get errors..

E: Could not open lock file /var/lib/dpkg/lock - open (13:Permission denied)

E: Unable to lock the administration directory (/var/lib/dpkg), are you root?

This is going to seem confusing after Piotr's message, but what you need is "sudo apt-get install python3-enchant".

The difference is follows:

* apt-get is the way to install system packages on ubuntu. It will install a version of the requested software that the ubuntu maintainers have verified works harmoniously with the rest of the operating system. You need to be root to do it.

* pip (and "python -m pip", which is equivalent) is the way to install python packages. It's dangerous to do this to your system python because what it installs has not been verified to work harmoniously with the OS (hence Piotr's warning)

Hope that clears things up.

that's the one where you need root rights (f.e. with sudo's help)
