Issues ****** I had major issues upgrading to the 2.0 series. To solve the problems, edit ``.bashrc`` from: :: source /usr/local/bin/virtualenvwrapper_bashrc to :: source /usr/local/bin/virtualenvwrapper.sh **and** :: sudo pip uninstall virtualenv sudo pip uninstall virtualenvwrapper sudo pip install virtualenvwrapper ImportError: No module named virtualenvwrapper.hook_loader ========================================================== When starting :doc:`../../linux/apps/tmux`. To solve the issue ``deactivate`` your virtual environment before starting ``tmux``. pip install virtualenv and virtualenvwrapper ============================================ Lots of build errors trying to install ``virtualenv`` and ``virtualenvwrapper``. To solve the problem, reinstall ``setuptools``: :: sudo sh setuptools-0.6c11-py2.7.egg
