python - SSLError installing with pip

Question

I'm trying to install Django on a windows 10 .

Whatever I try to install with pip on cmd, I get those errors

Collecting django

I've tried a lot of things from other questions but none is working.

pip install --upgrade pip --trusted-host pypi.org --trusted-host files.pythonhosted.org

pip install --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org django

Answer 1

Setting up my proxy correctly fixed this for me as well. Problem was that I used the https protocol for my HTTPS_PROXY and https_proxy environment variable.

Use:

HTTPS_PROXY="http://username:password@proxy.example.com:8080"
https_proxy="http://username:password@proxy.example.com:8080"

Do NOT use:

HTTPS_PROXY="https://username:password@proxy.example.com:8080"
https_proxy="https://username:password@proxy.example.com:8080"
