Errors in installation of matplotlib and pandas on Macbook

[Madhavan Bomidi]

Hello everyone,

I am very new to Macbook and python. I have installed python through MacPorts and when I check if all the packages I required are installed properly, I get the following traceback errors for matplotlib and pandas packages. Can anyone suggest me how I can rectify the same? I tried to check the file "/usr/local/lib/python2.7/site-packages/matplotlib/__init__.py" using vim command but it is empty. Please suggest me ...

Apple already includes a(n obsolete) version of Python with its OS. Trying to override this with a newer version could easily lead to conflicts.

[Madhavan Bomidi]

Can you please suggest me what I shall do to make sure all the libraries that I have indicated above work in python? I don't know how I can get back to obsolete version of Python. Please suggest me the commands or references of previous posts, if any.

Thanks and regards,
Madhavan

This looks like a problem in your environment. "UTF-8" is not a
locale; usually you'll want something else first. For me, it's
"en_AU.utf8" (although I believe UTF-8 works fine in place of utf8).
What language do you primarily speak, and what country are you in? Put
their two-letter codes together, and you'll get something like
"en_US.utf8" (English, USA), or "tr_TR.utf8" (Turkish, Turkey), or
"pt_BR.utf8" (Portuguese, Brazil). Once you know what locale you want
to be using, though, you'll need someone who knows Macs to help you
select that appropriately. Worst case, run this command before
starting Python:

export LC_ALL=en_AU.utf8

That may help.

Hello ChrisA,

Thanks for your suggestion. My script works fine when I run the command 'export LC_ALL=en_AU.utf8' before starting python.

I am from India and using US English and international keyboard. I also tried using the command 'export LC_ALL=en_USA.utf8' and the python script works fine. How can I avoid running this command everytime when I want to start Python?

Can I add the following two lines to .bash_profile?

export LC_CTYPE=en_US.utf8
export LC_ALL=en_US.utf8

Look forward to your response.
Thanking you in advance,
Madhavan

That would possibly work, but more likely, there'll be some way in
your Mac's configuration/settings menus to set your locale. If you get
that set correctly, you should be able to leave those lines out of
your .bash_profile and still have everything work.

Hello ChrisA,

Thanks for your suggestion. I have typed the following on Terminal:

$ locale
LANG=
LC_COLLATE="C"
LC_CTYPE="C"
LC_MESSAGES="C"
LC_MONETARY="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_ALL="C"

How should I modify the profile/configuration of locale permanently? Is it possible to do this on terminal other than using 'export' command always and including the commands in .bash_profile?

How does this locale configuration affect other processes or software on the Macbook?

I also get another problem with selfupdate of Mac port. Below is the error message. Is this a problem of configuration in the locale?

These are all Mac-specific questions (and not, incidentally,
Python-specific). You'll probably find you can learn a lot from
Googling your problems. (Or DuckDuckGoing them, but that doesn't roll
off the tongue so easily.)

Hi there,

Why you would not use pip and anaconda for panda installation?
It seems much easier to do the same.
