I was following this tutorial
When I got to virtualenv flask command, I received this error message:
Can not perform a '--user' install. User site-packages are not visible in this virtualenv.
This makes sense as the point of virtualenv is to create a new environment which you can control, and the --user command places everything in a specific location, defeating the objective of separation of dev environment.
It seems like pip defaults to --user installations though, can I change this default behavior? And, even better, can I get pip to play nice with virtualenv at all times?
To clarify, here is what my terminal looks like.
