Install matplotlib module in python

I am trying to install matplotlib in python. But getting ModuleNotFoundError.

I tried installing matplotlib in the linux command prompt with 

sudo pip install matplotlib

I got the message:

Successfully installed matplotlib-2.2.4

But I could not find the package in Linux.

Also when I try to import it in Python I am getting 

import matplotlib
ModuleNotFoundError: No module named 'matplotlib'

I expect matplotlib to be installed but I have the error

ModuleNotFoundError: No Module named 'matplotlib'

$ sudo pip install matplotlib

You may as well $ sudo pip uninstall matplotlib since that's not doing you any good.

Using sudo changes your environment. In particular it may change $PATH and hence change the output of $ which python, which matters for your import. The env var PYTHONPATH can also be relevant, as it affects sys.path.

Verify that $ which python and $ python --version return what you expect.

Issue these commands:

$ python -m pip install matplotlib
$ python -c 'import matplotlib'

Expected output is that the import silently succeeds.

If you continue to have trouble, inspect the path variable and ls -l the directories it mentions:

$ python
>>> import pprint, sys
>>> pprint.pprint(sys.path)

Consider using conda to manage your library dependencies.
