当我同时拥有python2和python3时，如何通过pip安装python2软件包？

Question

Now

pip -V

shows that it's python3.5's pip.

What to do if I want python2's package?

Answer 1

You can use $pip2 install [package name] as it says in the comments but down the road your life will be much easier if you use virtual environments to compartmentalize your code. That way you specify which python version to use in your project only once (at the beginning) and then you can configure pip to always install packages for that version.
