Downgrading Python Setuptools

Question

I am getting an error while attempting to use Pyinstaller. After doing some research I believe the error is caused by a bug in the most recent version of setuptools (19.3). The fix seems to be downgrading to setuptools version 19.2. My issue is with the downgrade itself. My question is how does one downgrade setuptools in Ubuntu 15.04?

Answer 1

Just specify the version using pip:

pip install setuptools==19.2 

If you are installing globally you will obviously need sudo.

~$ sudo pip install setuptools==19.2
Collecting setuptools==19.2
