 Problem Description:

When using the virtualenvwrapper create a virtual environment in such an environment, the following error occurred

/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.

The reason is the following code in virtualenvwrapper.sh

# Locate the global Python where virtualenvwrapper is installed.
if [ "${VIRTUALENVWRAPPER_PYTHON:-}" = "" ]
then
    VIRTUALENVWRAPPER_PYTHON="$(command \which python)"
fi

So, when virtualenvwrapper initialization command " Which Python " is called python2.7, and my virtualenvwrapper by pip3 download, so there will be error " No Module named virtualenvwrapper "

Solution:

Directly modify its command statement

VIRTUALENVWRAPPER_PYTHON="$(command \which python3)"
