Virtualenvwrapper - correct set up of .bash_profile

Question

I am running python3 on Linux Mint, and am trying to set up VirtualEnvWrapper.

I have both virtualenv and virtualenvwrapper installed: Running sudo pip3 install virtualenv , returns Requirement already satisfied: virtualenv in ./.local/lib/python3.5/site-packages (15.1.0)

Running sudo pip3 install virtualenvwrapper , returns Requirement already satisfied: virtualenvwrapper in /usr/local/lib/python3.5/dist-packages (4.8.2)

virtualenv is in /home/username/.local/bin/virtualenv virtualenvwrapper.sh is in /usr/local/bin/virtualenvwrapper.sh

My .bash_profile looks like:

source ~/.profile
export WORKON_HOME=~/Envs
export PROJECT_HOME=$HOME/Devel
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv
source /usr/local/bin/virtualenvwrapper.sh

When I run source ~/.bash_profile and then mkvirtualenv TestEnv , I return the following error:

bash: /usr/local/bin/virtualenv: /usr/bin/python: bad interpreter: No such 
file or directory

I think this is an issue with my .bash_profile and the location of the virtualenv vs virtualenvwrapper files. Is anyone able to help me correct my bash_profile to resolve this. I have tried various solutions offered on other threads, but none have helped.

Many thanks

Addition: This is a selection of the contents of my /usr/bin directory (ie ls ). I'm not sure why python is in red but it is neither a file nor a directory

Since you're using python3, I would check this file: /usr/local/bin/virtualenv . Be sure that, on the 1st line there you have something like:

#!/usr/bin/python3

Save the file and try again.

I'm pretty sure that right now you have /usr/bin/python which most probably referrs to python2 and not 3. So you're trying to run a python3 script using python2 (that's why you get a bad interpreter error).

Since /usr/bin/python is a symbolic link to a file that no longer exists at that location, the /usr/bin/python is show with red.

Delete it with sudo: sudo rm -f /usr/bin/python Then re-create the symlink using the following syntax: ln -s /path/to/source /path/to/destination (in your case /usr/bin/python)

Then try execute /usr/local/bin/virtualenv and see if it works.
