Hi @sai306!

Are you working behind a proxy?

Yes. I am working in a corporate environment.

@sai306 You can workaround this by using --trusted-host="pypi.python.org"

[pradyunsg]

Your proxy seems to be making it difficult for pip to validate the SSL certificates.

You should be able to workaround this by trusting the host machines for pypi.org, files.pythonhosted.org and pypi.python.org; albeit that's not the most secure solution.

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

[pradyunsg]

Closing since I don't see anything actionable here for pip. :)

I solved it just now ! what we have to do is to add --trusted-host ! For instance:

python -m pip install --upgrade pip --trusted-host=pypi.python.org --trusted-host=pypi.org --trusted-host=files.pythonhosted.org

Hope it will be helpful !

[archmangler]

The trusted host workaround does not work anymore because pip has disabled non-ssl connections.

"--trusted-host=pypi.python.org --trusted-host=pypi.org --trusted-host=files.pythonhosted.org"
