How to set up a Virtual Environment and Virtual Environment Wrapper on Ubuntu?

Virtual Environment Wrapper is a management tool for virtual environments. It is easy to access, create and delete virtual environments using a virtual environment wrapper. The objective of this blog is to help my fellow readers, set up a Virtual Environment Wrapper in Linux OS.

Pre-requisite

To follow along with the blog, you're gonna need pip installed in your system. If you haven't, then you can read my blog about creating a virtual environment.

Install Virtual Environment Wrapper

Open command terminal:

 pip install virtualenvwrapper

Make a directory for storing virtual environments.

mkdir ~/.virtualenvs

Set the directory as the go-to directory for the wrapper.

export WORKON_HOME=~/.virtualenvs

Provide a Virtual Environment Wrapper path to your Python installation.

VIRTUALENVWRAPPER_PYTHON='/usr/bin/python3'

Provide the path to the wrapper for the start-up shell

source /usr/local/bin/virtualenvwrapper.sh

Create a virtual environment

mkvirtualenv yourEnvName

This command will create as well as activate your environment at once. You'll probably see two environments, your base environment, and the newly created environment.

Deactivate the virtual environment with:

deactivate

Check the list of environments in your wrapper with:

workon

Switch the environments with:

workon envronment_name

WorkOn command not found

Now, when you close the terminal and then restart it, and then type "workon", the terminal will not recognize workon command. It's because we have yet to add the settings permanently in .bashrc and .bash_profile files.

On BashRc File

Open the bash file on Nano editor.

nano ~/.bashrc

On the BashRc file go to the end of the line (where doesn't matter, it's just to keep it simple) and add the following lines

#Virtual Env Wrapper settings
export WORKON_HOME=~/.virtualenvs
VIRTUALENVWRAPPER_PYTHON='/usr/bin/python3'
source /usr/local/bin/virtualenvwrapper.sh

Now, Press Ctrl+S to save the file and Ctrl+X to exit.

On Bash_Profile File

Open the file on Nano editor.

nano ~/.bash_profile

Add the following towards the end.

# For Virtual Wrapper
source ~/.local/bin/virtualenvwrapper.sh

Now, Press Ctrl+S to save the file and Ctrl+X to exit.

After this, you're all set. Close and reopen the terminal and type workon, it'll list all the environments in your wrapper.
