title: I installed a package outside virtual environment but cannot use it in the virtual environment
body: <p>I've installed the package Pillow outside the virtual environment created using pipenv. But when I try to make migrations for my django project in this environment, it says Pillow is not installed and asks to install it. I think I installed pillow globally but it is not accessible by the pipenv virtual environment. I'm using python 3.8 and use sublime3 as editor.</p>
