title: How should I install packages while working with a large number of virtual environments?
body: <p>Let's say I need to make 10 small projects with NumPy so I am making 10 virtual envs. Do I need to &quot;pip install numpy&quot; every time?</p>
  <p>I know that for any project in python it's  recommended to work on a Virtual enviroment so I want to work on it. But I don't want to install libraries every time, it takes a lot time on my laptop.</p>
  <p>Is there any more effective way to work with venv ?</p>
