Python could not import the module virtualenvwrapper.hook_loader?

Question

If Python could not import the module virtualenvwrapper.hook_loader, and I get this message

check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3 and that PATH is
set properly.

How do I start to set it up in Debian 9?

How did you start? I.e., how did you install virtualenvwrapper? – Parenthesis

all dependencies with virtualenwrapper is installed with pip. – Kwon

pip, not pip3? pip is for Python 2.7, but you error shows python3. – Parenthesis

Answer 1

You have to install virtualenvwrapper separately for different versions of Python:

pip install virtualenvwrapper
pip3 install virtualenvwrapper

The first one is for Python 2.7, the second for Python 3.

Parenthesis

-bash: /usr/local/bin/virtualenvwrapper.sh: No such file or directory, but solved original error in question. – Kwon

That's strange. pip install should install both the module and shell scripts. Did both pip install finish successfully? – Parenthesis

I uninstalled for pip and installed successfully for python 3. – Kwon

Answer 2

Installing virtualenv by both, pip and pip3 doesn't make any sense because installing it by any one shows virutalenvwrapper in both, pip list and pip3 list.

The right way is to copy the following code in your ~/.bashrc.

VIRTUALENVWRAPPER_PYTHON=$(which python3)

NOTE: Use the python version you want to use, in my case it's python3.

running which python3 in my terminal and then using it as [which python3 path]/virtualenvwrapper.sh did the trick for me! – Aedes

Answer 3

you need to change VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3 to VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3 for MacOS

for me on Mac it's source /opt/homebrew/bin/python3/virtualenvwrapper.sh – Aedes
