I am tying to install Flask-MongoEngine with Python 3.4 which is what is installed on my Mac. When I attempt to install Flask-MongoEngine via pip3 I am getting the following error and not sure how to resolve it?

sudo pip3 install Flask-MongoEngine

This is a helpful answer. Switching to a different Internet connection resolved the issue for me. – Saïd Jun 26 '19 at 16:53

try installing it with pip instead of pip3 and then it mostly asks u to update it. This might help : python -m pip install –upgrade pip

This is an old question, which probably was due to an issue mentioned here in the project's `setup.py`: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=242785 – kaveh Aug 14 '20 at 23:06
