1 year ago This appears to be an issue with urllib3 related to use of proxy servers: https://github.com/pypa/pip/issues/9972
try running upgrading pip first:
mayapy -m pip install -U pipThen run the pymel installation.
If that doesn't work, then you may need to try some of the suggestions from the issue above, including "uninstalling any proxy software or remove proxy settings".
Error when I enter code :
mayapy -m pip install "pymel>=1.2.,<1.3."
to install module
