Virtualenvwrapper: no module named virtualenvwrapper

Question

I'm trying to get virtualenvwrapper running. I install it with:

sudo pip install virtualenvwrapper

I edited the .bashrc like this:

export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/Devel
export VIRTUALENVWRAPPER_SCRIPT=/usr/local/bin/virtualenvwrapper.sh

When I try to run "source ~/.bashrc" I get this error:

/usr/bin/python: No module named virtualenvwrapper
virtualenvwrapper.sh: There was a problem running the initialization hooks.

If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON=/usr/bin/python and that PATH is
set properly.

I installed pip, python and virtualenv in the following directories:

which python
/usr/bin/python

which pip
/usr/bin/pip

which virtualenv
/usr/local/bin/virtualenv

What am I doing wrong?

What the os environment variable `VIRTUALENVWRAPPER_PYTHON` equals to? Try to set it as the error tells you: `VIRTUALENVWRAPPER_PYTHON=/usr/bin/python` — Chen A., Nov 23 '17 at 14:52
When I add this in my .bashrc, the error still remains the same — Alex, Nov 23 '17 at 14:59
yes, if I change from tcsh to bash it immediately shows the same error message — Alex, Nov 23 '17 at 15:11
I have installed python 2.7.9 and 3.4.2, but in my virtualenv I use the 3.4.2 — Alex, Nov 23 '17 at 15:17

I think you need to

pip3 install virtualenv virtualenvwrapper

and add this to your ~/.bashrc file

 export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3

This is because your virtualenvwrapper is pointing to python3. I just resolved mine now. Thanks to this help

Your error happens because you installed virtualenv for Python 2.7, but you try use it with Python 3. Use pip3 to install Python 3 packages on multi-version system.

pip uninstall virtualenvwrapper
pip3 install virtualenv virtualenvwrapper

Check the output for `python -v`. That's the default one, which points to `/usr/bin/python`. This error usually indicates version conflicts. If it says 2.7, then use pip install for both virtualenv and virtualenvwrapper modules. Else use pip3 to install both. – Chen A. Nov 23 '17 at 15:59

@ChenA. To check for python version, instead of small "v", it should be capital "V": `python -V` – Eje Aug 21 '18 at 10:28

You need to source /usr/local/bin/virtualenvwrapper.sh in your .bashrc (you don't need to export it).
