I'm on MacOs Sierra.
I'm having an issue where installing my own package with sudo pip install -e results in /usr/local/lib/python2.7/site-packages/easy-install.pth being updated to point to the package but apparently not found when python starts up.
This smells like it's related to my having linked /usr/local/bin/python to /usr/bin/python some time back to address some other version conflict type issue that I can no longer recall.
Is there a sensible way to address this by editing something in, say, site.py?
I'm not sure what additional specifics might be needed here. Here's a plethora of related command output from the system.
The pip install seems to succeed:
~$ cd workspace/mypackage
mypackage$ sudo -H pip install -e .

Here's how the python versions look. Again, the link to /usr/bin/python (and moving the original /usr/local/bin/python to -cellar) was a workaround for another (MacOs python specific, IIRC?) issue I was having previously.

The -cellar-ed version of python does find the install:
$ /usr/local/bin/python2.7-cellar -c 'import mypackage; print mypackage.__file__'
/usr/local/lib/python2.7/site-packages/mypackage/__init__.pyc
The easy-install.pth that was updated by the install is in /usr/local/lib.
tmp$ sudo find /usr -name easy-install.pth
