在Python 3.4+中安装Flask而非python2.7

Question

So, I know how to actually install flask, via pip install Flask

But, I'm running a virtualenv with python3.4 . The problem is, Flask is in fact installed. The problem is though, it is installed for python2.7 and not python3.4 .

I did run this command with the virtualenv activated via source bin/activate , but it seems to install it for python2.7 even though a virtualenv running python3.4 is activated.

How do I fix this? im pulling my hair out over this.

Thanks

Answer 1

Since Python 3.3, you can use venv instead of virtualenv (see PEP 405 ). If you do so, running source bin/activate will set python command to python 3 and use the right pip.

you can create the environnement using:

python3 -m venv myEnvName

Hope this helps

If you are using Pycharm just switch to python 3, and there is a list of packages installed. Hit add(+), and look for flask

You can switch to python 3 by hitting file-> setting -> Project:Projectname -> Project Interpreter
