How to run a virtual environment on linux?
First installed pip: sudo apt-get install python3-pip
Then virtualenv: sudo pip3 install virtualenv
Then created: virtualenv venv
Then entered the command: virtualenv -p /usr/bin/python2.7 venv
But when I wanted to run: source venv/bin/ activate
gave an error, how to fix it?
