Matplotlib was working fine few months back. But now I keep getting the error:

ImportError: No module named matplotlib

I again installed matplotlib using pip. It didn't work. I used easyinstall. Still not working.

pip installation gives

Then I used

sudo -E pip install matplotlib --upgrade

after which i got

You are using pip version 6.1.1, however version 7.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

It continued upgrading matplotlib but in the end i got

    Check your `which python` path. – JRodDynamite Nov 24 '15 at 08:33
  • Please show output of `pip list` – Tomasz Jakub Rup Nov 24 '15 at 08:33
  • Read the answers to this question: [Pip Install not installing into correct directory?](http://stackoverflow.com/questions/25607837/pip-install-not-installing-into-correct-directory) – k4ppa Nov 24 '15 at 08:36
  • @TomaszJakubRup matplotlib (1.3.1) is available in pip list – ruskin23 Nov 24 '15 at 08:36
  • @JasonEstibeiro /Library/Frameworks/Python.framework/Versions/2.7/bin/python I think this is fine – ruskin23 Nov 24 '15 at 08:37
  • @k4ppa which python shows the directory is correct. – ruskin23 Nov 24 '15 at 08:40
  • `python -m pip install --upgrade matplotlib ` – Peter Wood Nov 24 '15 at 08:44
  • @PeterWood I used sudo -E pip install matplotlib --upgrade and this is what i got DEPRECATION: Uninstalling a distutils installed project (numpy) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project. And then Uninstalling numpy-1.8.0rc1: Exception: Traceback (most recent call last): File "/Library/Python/2.7/site-packages/pip/basecommand.py", line 246, in main status = self.run(options, args) – ruskin23 Nov 24 '15 at 08:44
  • `brew install matplotlib` – Pavleg Nov 24 '15 at 08:44

On OS X do not ever install python modules as root, is a quick recipe for never ending failures.

Use the --user parameter for pip in order to install modules for the current user only, like:

localhost:~ sorins$ which python
/usr/local/bin/python

python -m pip install --user --upgrade matplotlib

Also, be sure that you are using the correct python interpreters, as it happens often for pip to get confused and to install a module in a location than is not included in the python PATH (sys.path).
