Recently I try to install some package or update the pip, similar error message pops out. 

Exception:
Traceback (most recent call last):

I think that might due to an improper uninstallation of python on macport cause it, as when I try to change different python with the use of 

port select --list python

and 

sudo port select --set "python name"

and when I type 

which python

all of them leads to 

/opt/local/bin/python

none of them connected to the Frameworks. I wanna ask is there anyway to restore the mac preinstalled python?

  • So what does `port select list python` show (update your question with the output)? Also the error shows you are attempting to update a system file in `/Library`, which is wrong. Have you seen [this](http://stackoverflow.com/questions/17271319/installing-pip-on-mac-os-x)? – Droppy Jun 29 '16 at 12:40

  • @Droppy when I type port select --list python these shows up none python26-apple python27 (active) python27-apple but all of them just connected to /opt/local/bin/python . – Peter Pang Jun 29 '16 at 12:48
  • @Desrif, I have try the link previously but it just does not work. – Peter Pang Jun 29 '16 at 12:48
  • @Droppy I have tried the link and reinstalled pip as shown in the link. But the same error pops up when I try to update it. – Peter Pang Jun 30 '16 at 09:39

The problem was solved simply by running 

sudo pip install --upgrade pip
