如何在pycharm中相应地选择python版本？

Question

In last project, I used python 2.7. The new one have to run in python 3.5 so I installed 3.5. I choose Python 3.5 in Setting-->Python interpreter, and I got Error : Django is not importable in this environment. Then I tried to run

 pip install django
Requirement already satisfied (use --upgrade to upgrade): django in c:\python27\lib\site-packages
Cleaning up...

It seems that something wrong with the path, and how could I make it right?

Answer 1

It's probably because the pip command points to python2.7 version of pip, and as django is already installed for python 2.7, you are getting the message you mentioned.

You need to install django for python3.5. To do that, either directly run pip executable inside python3.5 folder, or choose python3.5 as the interpreter from pycharm, and install django through the ui of pycharm.

Depending on how you installed python3.5, you could also run

pip3.5 install django

from the console to invoke python3.5 version of pip

Answer 2

只是去pip3适合Python的3倍ENVS：

   pip3 install Django
