Error in installing matplotlib

Question

I'm installing matplotlib in python on linux.

I used the following command to install.

pip install matplotlib

It's showing the following error:

error: [Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/pylab.py'

Answer 1

Try:

sudo pip install matplotlib

Your user account doesn't have permission to write to /usr/local/lib/python2.7/dist-packages , but root does.
