Python Question

bash: /usr/local/bin/fab: /usr/local/opt/python/bin/python2.7: bad interpreter: No such file or directory

Fabric is not working for me. I get the following error when I run fabric.

fab realm:prod role:tools,1 build
bash: /usr/local/bin/fab: /usr/local/opt/python/bin/python2.7: bad interpreter: No such file or directory

It used to work before. But I am not sure what really changed.
I had run the below commands

brew doctor
brew install git

I don't know how those brew commands could mess with my python version

$ which python
$ ls -l /usr/local/bin/python
lrwxr-xr-x 1 vaibhav.chidrewar admin 68 Nov 8 2014 /usr/local/bin/python -> ../../../Library/Frameworks/Python.framework/Versions/2.7/bin/python
$ which pip
$ which fab
$ head -n1 /usr/local/bin/pip

$echo $PATH

I tried uninstalling and reinstalling pip and fabric. But even after that I get the same error.

$ sudo easy_install pip

Requirement already satisfied (use --upgrade to upgrade): paramiko>=1.10,<2.0 in ./Library/Python/2.7/lib/python/site-packages (from fabric)

Cleaning up...

After that I tried install Flask and it worked.
So not sure whats wrong with Fabric.

Answer Source

I found that my .bash_profile was not getting sourced. So following was missing.

export PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"

For now I copied the contents of .bash_profile to .bashrc and things are working fine again
