问题
I have researched this for hours to no avail.
I think I deleted my directory at /usr/bin/python when I installed python 3 because I get this error: -bash: /usr/bin/python: No such file or directory.
I've tried sudo ln -s /usr/bin/python2.7 /usr/bin/python, and that gives me ln: /usr/bin/python: File exists
However, it still doesn't permanently install a directory in /usr/bin/python. How do I permanently restore this directory?
I'm on a mac.
Thanks!

Your file /usr/bin/python exists because you get the message:
ln: /usr/bin/python: File exists
but I see that it is a corrupted link to something that doesn't exist, because you get the message:
-bash: /usr/bin/python: No such file or directory
What you have to do to fix that is:
sudo rm /usr/bin/python # because that's a corrupted file
sudo ln -s /usr/bin/python2.7 /usr/bin/python # this line will work if your file /usr/bin/python2.7 is OK.
Hope that helps!
