You are using pip version 9.0.1, however version 18.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Installing the PyCharm package from terminal:

$  pip3  install --user  parallel

Answer 1

I downloaded & opened the tar.gz file from that pypi cache url to make sure, and confirmed that what you were trying to do was to install a module that was both abandoned & didn't even passed status alpha since 2007 , for Python 3. That will never work. I'd suggest not to install the author recommendation module as well given that it's also isn't maintained since 2016.

You can use "from joblib import Parallel,delayed". just install joblib.
