You should consider upgrading via the '/usr/local/bin/python3.10 -m pip install --upgrade pip' command. As of Python 3.10, OpenSSL 1.1.1 or newer is required: https://www.python.org/dev/peps/pep-0644/ Please guide me in installing OpenSSL version 1.1.1 Thanks in advance and I look forward to hearing from you.
