problems with python and virtualenvwrapper after updating: No module named virtualenvwrapper

If you have modified your virtualenvwrapper to point to python3, like I do, add the following line in your .bashrc file :

export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3

making sure that it's placed before the following line (if you have it):

source /usr/local/bin/virtualenvwrapper.sh

Then, make sure you install the virtualenv and virtualenvwrapper using:

sudo /usr/local/bin/pip3 install virtualenv virtualenvwrapper

You need to install them under python 2.7.9 by specifying the path to correct version of pip to be used

/usr/local/bin/pip install virtualenv virtualenvwrapper

otherwise, when running pip install the sytem will use the default one (i.e. the one located at /usr/bin/pip)
