如何为特定版本的Python安装matplotlib？

Question

I have installed scipy and numpy, and they are being used with my current, desired version of python 2.7.6 (I am running on OSX Mavericks and had to upgrade.) However, when I pip installed matplotlib, by default it referenced my previous python version, 2.7.5, thus making it troublesome to use (obviously.)

How do I change which version of python matplotlib uses so I can import and use the library?
Thanks.

Answer 1

The way I would solve this problem is like this, firstly one would need to go into your 2.7.6 directory, and under the Scripts folder you will find the pip executable. My suggestion is (because its difficult to debug this kind of people without having all the details) is this:

./pip install matplotlib

And see if this succeeds, otherwise, I suggest using pyenv to manage your python installations.

Answer 2

I suggest you use Macports for installing additional Python versions on OS X. Once Macports is installed, it's fairly easy to install Python 2.7.6. All you'd have to do is:

sudo port install python27

Now, you should be able to get all the libraries you need just as easily, using, too, Macports.

sudo port install py27-numpy
sudo port install py27-scipy
sudo port install py27-matplotlib

Macports should solve all the dependencies and, of course, link the packages to their correct Python versions, avoiding you a lot of headaches.
