pip: cert failed, but curl works

Question

We installed the our root cert on the client, and the https connection works for curl.

But if we try to use pip, it fails:

Answer 1

For me, none of the config-file workarounds worked. I'm using pip 1.5.4 on Ubuntu 14.04

The command posted by @arjenve didn't work on my system either. I get: /usr/bin/python: No module named _vendor.requests

UPDATE

An even better solution than my first workaround is installing the certificate on the system first (for me on ubuntu this would be)

sudo cp ~/my_cert.crt /usr/local/share/ca-certificates/
sudo update-ca-certificates

The previous automatically updates the bundle file (checking at the bottom of /etc/ssl/certs/ca-certificates.crt you should now see the same certificate as in my_cert.crt)

Now export that path into PIP_CERT and add it to your .bashrc:

echo export PIP_CERT=/etc/ssl/certs/ca-certificates.crt >> ~/.bashrc

OLDER WORKAROUND

My workaround was to create a bundle file from /etc/ssl/certs/ca-certificates.crt and my corporate's crt (just concatenated both files). And then export a variable (put that on my .bashrc) like this:

export PIP_CERT=/my/path/to/the/bundle.crt
