I just installed Python 3.7 from python.org. I followed this StackOverflow post to change my default Python to Python 3. From there I ran the Update Shell Profile.command and Install Certificates.command (Finder > Applications > Python 3.7).

Then I found that I couldn't run the pip command 

> $ pip --version

> -bash: pip: command not found

Subsequently I ran the following 2 commands..

> $ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
> 
> $ python get-pip.py

This is what I don't understand

What is the wheel and how do I add this to the correct path?

> $ which python

> /usr/local/opt/python/libexec/bin/python

What is the wheel and how do I add this to the correct path?

  • This indicates that the location of `pip` is not considered when you enter `pip` on the commandline. Instead changing this path you can try `python -m pip --version` for example. This should achieve the same as `pip --version`. – rocksportrocker Sep 27 '18 at 15:29
  • I ran that and got .. pip 18.0 from /usr/local/lib/python3.7/site-packages/pip (python 3.7) What about the script wheel? Which directory do they want me to add? – Kevin T. Sep 27 '18 at 15:44
  • you should extend the environment variable `PATH` with `'/Users/kevinturney/Library/Python/2.7/bin'`, see also https://stackoverflow.com/questions/14637979/how-to-permanently-set-path-on-linux-unix or https://askubuntu.com/questions/60218/how-to-add-a-directory-to-the-path – rocksportrocker Sep 27 '18 at 15:51
  • Even though I my path for python 3 ($ which python) is /usr/local/opt/python/libexec/bin/python? I'm confused, do I add it to this path or to the one above .../usr/local/lib/python3.7/site-packages/pip (python 3.7). In my .bash_profile at the bottom I have .. PATH="/Library/Frameworks/Python.framework/Versions/3.7/bin:${PATH}" – Kevin T. Sep 27 '18 at 15:55
  • Yes, but the "--user" flag allows installation to a local folder where you have write access. So just extend your PATH manipulation with the given path. – rocksportrocker Sep 28 '18 at 14:02
