Why can't `virtualenv` find `pkg_resources`?

I\'m trying to use virtualenv in Ubuntu to install a local virtual Python environment. When I run the shell command:

1. Check the current version of virtualenv. As answered by user2676043 in the same thread, virtualenv is installed in /usr/local/lib/python2.7/dist-packages. So run the following command:

   $ python /usr/local/lib/python2.7/dist-packages/virtualenv.py --version

It will return you the version of virtualenv installed on system.

2. Now, change the executable file.

   $ vim /usr/local/bin/virtualenv

Change the version to the one received above. Save the file and it works smoothly.
