mkvirtualenv command not found – virtualenvwrapper

virtualenvwrapper is a set of extensions to Ian Bicking’s virtualenv tool. The extensions include wrappers for creating and deleting virtual environments and otherwise managing your development workflow, making it easier to work on more than one project at a time without introducing conflicts in their dependencies.

Solution 1:

For some reason, virtualenvwrapper.sh installed in /usr/bin/virtualenvwrapper.sh, instead of under /usr/local/bin.

Add following to your .bash_profile

source "/usr/bin/virtualenvwrapper.sh"
export WORKON_HOME="/opt/virtual_env/"

Solution 2:

Alternatively as mentioned below, you could leverage the chance that virtualenvwrapper.sh is already in your shell’s PATH and just issue a source `which virtualenvwrapper.sh`

Use this procedure to create virtual env in ubuntu

Step 1

Install pip

   sudo apt-get install python-pip

step 2

Install virtualenv

   sudo pip install virtualenv

step 3

Create a dir to store your virtualenvs (I use ~/.virtualenvs)

   mkdir ~/.virtualenvs

or use this command to install specific version of python in env

virtualenv -p /usr/bin/python3.6 venv

step 4

   sudo pip install virtualenvwrapper

step 5

   sudo nano ~/.bashrc

step 6

Add this two line code at the end of the bashrc file

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

step 7

Open new terminal (recommended)

step 8

Create a new virtualenv

  mkvirtualenv myawesomeproject

step 9

To load or switch between virtualenvs, use the workon command:

  workon myawesomeproject

step 10

To exit your new virtualenv, use

 deactivate

and make sure using pip vs pip3

OR follow the steps below to install virtual environment using python3

Install env

python3 -m venv my-project-env

and activate your virtual environment using the following command:

source my-project-env/bin/activate

or if you want particular python version

virtualenv --python=python3.7.5 myenv
