version – Which python am I using?
version – Which python am I using?
❯ echo `which python`
If this doesnt print /usr/local/bin/python (where brew actually installs binaries), then theres something wrong with your $PATH (probably /usr/local/bin is not there or its inserted after /usr/bin, so the system default python is being run instead).
++ it seems that brew names its python2.7 as python2 by default, and not as python, so you may also need to create a python2->python link in /usr/local/bin directory.
Do you have separate environment variables set up for each?
I have found in the past that having multiple versions of python 2 for example, without all the environment variables, can get quite confusing!
You may find when typing python3, windows is only looking at python 3.0, unless you are in the python 3.6.2 directory.
version – Which python am I using?
First I modified my $PATH: sudo nano /etc/paths so that /Library/Frameworks/Python.framework/Versions/3.6/bin was not being invoked. I made sure my paths were in the right order so that python looked for /usr/local/bin/python3 and /usr/local/bin/python2 first to force the issue.
However, $ python3 --version still returned
Python 3.6.0, though brew says python3 3.6.2 already installed.
brew doctor to the rescue: homebrew recommended a couple things. python was incorrectly symlinked so I ran brew --overwrite python3. Finally, it diagnosed python coming from /Library/Frameworks/Python.framework/Versions/3.6/bin, so I sudo rm -rf /Library/Frameworks/Python.framework. Now python versions are correct.
Thank you everyone for your help.
