  • python3.7 is a directory, is python inside it? Commented Dec 10, 2019 at 12:28

A more elegant solution is to create a separate environment for different python. Anaconda is the way to go. It is free and it installs many everyday libraries already.

Download and install the python 3.7 version. And then create a python 2 version is simple:

conda create -n py27 python=2.7

Every time you need the 2.7, just

conda activate py27

And then you can install libraries there just for 2.7, without messing up your 3.7. Vice versa for 3.7.

You should be able to choose your Python version with the two following commands:

>> python --version Python 2.7 >> python3 --version Python 3.7

If this works, just call pip like so:

>> python3 -m pip install everett
