/usr/bin/python3: Error while finding spec for ‘virtualenvwrapper.hook_loader’ (: No module named ‘virtualenvwrapper’)

I faced similar problem, when using python3 with virtualenvwrapper,

sudo apt-get install python3-pip

Then install virtualenv and virtualenvwrapper from pip3,

sudo pip3 install virtualenv virtualenvwrapper

then source it again,

source $HOME/.bashrc
