Python virtual environment

How to quickly create a virtual env for Python on Linux:

1. sudo apt install python3-pip to be sure that pip is installed.


2. pip3 install virtualenv to install virtualenv package.


3. mkdir ~/some_project to create a folder some_project in home directory.


4. cd ~/some_project to enter that folder.


5. virtualenv -p python3 venv to create a virtual environment directory venv with Python 3 as the interpreter.


6. source ~/some_project/venv/bin/activate to activate the virtual environment

Other commands:

deactivate to stop the virtual env.
rm ~/some_project to remove the virtual env.
