pip not working after installing python3 on Mac

问题:

I installed python3 from the official website and then installed jupyter notebook. While trying to run jupyter notebook, I was getting a "command not found" error.

I found this github issue and followed the instructions to delete python3 and reinstall using Homebrew instead (I've used Homebrew before).

When trying python3 -m pip install --upgrade pip i get a "No module named pip" error. My /usr/local/bin/ file shows pip, pip2, pip2.7, pip3, pip3.6.

I have a feeling my pip is not associated with the python3 that I installed using Homebrew. How can I fix this?

This way is a pretty fool-proof way to install pip for a specific python interpreter, when you have a big mess of them on the machine:

$ curl https://bootstrap.pypa.io/get-pip.py > /tmp/get_pip.py
$ my_python_interpreter /tmp/get_pip.py

Then:

$ my_python_interpreter -m pip install some_dist
