I am trying to get pyOpenSSL 18.0.0 but it doesn't work. Here are my commands:

sudo pip install pyOpenSSL==18.0.0

I get this:

The directory '/Users/mac/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

Looks like pyOpenSSL is already installed. But then I check:

pip list

And I get:

pyOpenSSL    0.13.1

The sudo command might be making pip install that version of pyopenssl to the site-packages of the root user. Simply running pip install pyOpenSSL==18.0.0 (outside of a virtual environment) should install it in the site-packages of the current user.

As an aside, you should consider using virtual environments for better dependency management of your python project. For that, please reference {this answer}.
