Python 2.7 on OS X: TypeError: 'frozenset' object is not callable on each command

Question

I have this error on each my command with Python:

➜  /tmp sudo easy_install pip
Traceback (most recent call last):
  File \"/usr/bin/easy_install-2.7\", line 11, in 
         


        

Answer 1

I had this problem too, but I also needed the hashlib package to be installed (On Debian).

The best solution that I found (Better then to install hashlib with easy_install) was from here: https://askubuntu.com/questions/770262/python-hashlib-fails-to-install-pip

And it is:

"The quick and dirty fix is to remove the /usr/lib/python2.7/lib-dynload/_hashlib.x86_64-linux-gnu.so file"

After this it is possible to install hashlib with pip!
