Python setup error code 1 in /tmp/pip-build-37eD7r/pandas/

Command "python egg_info" failed with error code 1 in /tmp/pip-build-37eD7r/pandas/

I just tried to update and got the above error. I Googled it with no result. Right now the update has frozen with a "500: Internal Server Error" and Im not sure what to do next. Any help would be great. Thanks.
