Fixes for the error 'mkvirtualenv: command not found' ?

One of our customers installed virtualenv and virtualenvwrapper, but still received the 'mkvirtualenv: command not found' error message. 

Here are the steps to properly install virtualenvwrapper.


1. Define the path virtualenvwrapper in the “.bashrc” so that the shell knows where the virtualenvwrapper.sh bash script resides. 

So locate where virtualenvwrapper.sh script is.

By default, the virtualenvwrapper is installed in the path:

/usr/local/bin

2. After running the “pip install virtualenvwrapper” command, first create a directory where all the virtual environments will reside. 

Here, we are putting them in “~/.environments”:

mkdir ~/.environments

3. Now open the “~/.bashrc” or “~/.profile” file and add the following to the end of the file:

export WORKON_HOME=~/.environments
source /usr/local/bin/virtualenvwrapper.sh

4. Finally, we need to inform the bash about the changes we made. 

For that, run the following command to re-load the .bashrc configuration OR just simply close the shell and re-open it:

source ~/.bashrc

Now, you must be able to run the mkvirtualenv command without any error.
