pip failling to install for Python 3.7 on MacOs

Question

I'm currently working on a Mac with Mojave. I have successfully installed python 3.7 with brew

    brew install python3

But I have tried several methods to install pip for python 3.7 (installing with get-pip.py, easy_install pip, etc.), which had worked for installing pip in the python 2.7 folder, but not in the python 3.7.

Currently when I call

  pip --version

I get

pip 18.1 from /Library/Python/2.7/site-packages/pip (python 2.7)

And pip3 seems not to exist.

How can I get pip3 installed in the python 3.7 folder? Thanks!

Answer 1

If you want to ensure pip installed for python 3.7, try something like this:

wget https://bootstrap.pypa.io/get-pip.py
sudo python3.7 get-pip.py

Answer 2

Ok, so I still don't quite understand what's going on with pip3 in my device, but I found a way to install packages with pip in the right Python version:

python3 -m pip install [package]

It worked to install numpy which was my primary objective.

Answer 3

Maybe you're using an older version of Brew?

In that case run brew postinstall python3
