Why am I getting this error? I have virtualenv and virtualenvwrapper installed. I'd like to use mkvirtualenv and workon. I find it odd that virtualenv is working, but virtualenvwrapper isn't.

Answer 1

1st, ensure you're installing with sudo:

sudo pip install virtualenvwrapper 

2nd, append the following lines to your .bashrc file (with nano ~/.bashrc):

export WORKON_HOME=$HOME/.virtualenvs source /usr/local/bin/virtualenvwrapper.sh 

3rd, reload your profile

source ~/.bashrc 

Answer 2

Summary

I'm on a Mac and my answer is similar to @Ramces answer except it was with bash_profile. I just want to elaborate a little further for Mac users to be aware that there's a lot of different profiles including:

• .bashrc
• .bash_profile
• .profile

Some files like .profile do not take precedence over .bash_profile (if it exists) and will then be ignored. If you successfully do the below steps and get a virtual env working, but then close out your terminal and 'workon command not found', then you need to setup for the correct profile. For a detailed answer, see here

Install Steps:

1. sudo pip install virtualenv

   Installs virtualenv (allows you to separate your envrionments)

2. sudo pip install virtualenvwrapper

   Installs virtualenvwrapper (allows you to use the 'workon' command)

3. nano ~/.bash_profile

   export WORKON_HOME=$HOME/.virtualenvs source /usr/local/bin/virtualenvwrapper.sh 

4. source ~/.bash_profile

   Reloads the profile. Going forward you only need step 5 (to create new environments) and step 6 (to run environments)

5. mkvirtualenv my_env

   This creates your virtual environment (this example is with 'my_env')

6. workon my_env

   This lets you work on a specific environment (this example is with 'my_env')
