Steven D'Aprano <steve+python at pearwood.info> added the comment:

``pip3 search multiprocessing`` says:

multiprocessing (2.6.2.1)            - Backport of the multiprocessing package to Python 2.4 and 2.5

so you are trying to install a Python 2.4/2.5 package into Python 3.7, which naturally cannot work.

In Python 2.6+ multiprocessing is a std lib module and you don't need to use pip to install it. I'm not sure if pip works with Python 2.4 or 2.5, but if it does, you'll need to use the 2.4/2.5 version of pip to do the update, not pip3.

I'm going to close this as not a bug. If you disagree, please give reasons why you think it should be reopened.
