Answer 1

I got same problem. If I run brew link --overwrite python2. There was still zsh: /usr/local/bin//fab: bad interpreter: /usr/local/opt/python/bin/python2.7: no such file or directory.

cd /usr/local/opt/
mv python2 python

Solved it! Now we can use python2 version fabric.

There is convinient way to use python2 version fab when your os python linked to python3. .sh for your command.

# fab python2
cd /usr/local/opt
rm python
ln -s python2 python

# use the fab cli
...

# link to python3
cd /usr/local/opt
rm python
ln -s python3 python

Hope this helps.

Answer 2

sudo /usr/bin/easy_install pip

this command worked out for me

Answer 3

In my case, I decided to remove the homebrew python installation from my mac as I already had two other versions of python installed on my mac through MacPorts. This caused the error message.

Reinstalling python through brew solved my issue.

Answer 4

Because I had both python 2 and 3 installed on Mac OSX I was having all sorts of errors.

I used which to find the location of my python2.7 file (/usr/local/bin/python2.7)

which python2.7

Then I symlinked my real python2.7 install location with the one the script expected:

ln -s /usr/local/bin/python2.7 /usr/local/opt/python/bin/python2.7

Answer 5

Yes. it seems it is a quite frequent problem. One solution is install Anaconda3, download Anaconda3-4.2.0-Linux-x86_64.sh and Anaconda3 will provide you python and pip at the same time and they are coordinated.

Answer 6

I made the same error using sudo for my installation. (oops)

brew install python
brew linkapps python
brew link --overwrite python 

This brought everything back to normal.
