Unable to install visvis using pip in python

Question

I successfully added pip to python on my ubuntu. However when I try to install visvis using pip:

pip install visvis

I get the following error:

error: could not create '/usr/local/lib/python2.7/dist-packages/visvis': Permission denied

How do I solve this? Btw, I am downloading visvis to easily plot hundreds of spheres. Any suggestions on what else I could use?

Answer 1

Run the command as superuser to install the package system-wide.

For example, use sudo:

sudo pip install visvis

Answer 2

Better if you use virtualenv for your packages: http://www.virtualenv.org/en/latest/
