ImportError: No module named matplotlib in IDLE

Question

When I want to import matplotlib in IDLE. The following error occurs:

ImportError: No module named matplotlib

I use mac, the PATH of python in my bash_profile is:

# Setting PATH for Python 2.7
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"
export PATH

Days ago I tried to uninstall python from my mac, so I am not sure if I just damaged built-in python.

How can I fix this problem?

I use sudo easy_install matplotlib to install it. And in the shell using python a.py it works fine. But still cannot find module in IDLE. — Zezhou Li, Feb 26 '16 at 17:12

Two things you can look into.

Python env variable for path is PYTHONPATH not just PATH. Change that.
Run this command and see the path indeed includes what you need.
```
$ python -c 'import sys; print(sys.path)'
```

Actually I found my matplotlib module in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python. How can I add it into the path file? – Zezhou Li Feb 26 '16 at 17:28
Just like you did earlier. But use PYTHONPATH instead of PATH – Hun Feb 26 '16 at 18:20
Just a reference, the command works in windows, but need to change the single ' to double ''. – zhihong Mar 21 '18 at 19:45
