Python install django & djangorestframework errors SSL issue

Fairly new to python and I'm having trouble adding django and djangorestframework on my "work" computer. On my home computer, it works fine, no issues. On my "work" computer, it bombs even though I use "--trusted-host pypi.org" etc. I'm on Win 10.

This is the error:

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1108)'))': /simple/pip/

I don't know if this is a "permissions" thing or what?

What I have tried:

I'm using python 3.8.0 with pip 19.3.1. I've looked at several things, ie curl get-pip from the bootstrap.pypa.io site etc to update pip but I'm not sure if that's the issue or not.

Thanks for the quick response! I'm using 3.8, not 3.7 and I don't see anything remotely related to Certificates.command in my 3.8 folder. I do see get-remote-certificate.py in the "Tools/scripts"..

And did you try to get remote certificates?

PeteLux36 29-Jan-20 14:21pm

I'm not sure how to do that. Do I need to download and then create the script?

Since it's a .py file, something like python.exe get-remote-certificate.py in a console may give interesting results.

you need to set pypi.org and files.pythonhosted.org as trusted hosts. Try this

$ pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org <package_name>

Also, since it's 'work' computer you need to check if the issue is a corporate proxy/firewall which might not be allowing traffic to pypi.org or files.pythonhosted.org.

I've tried that and I'll check if my firewall is blocking too.

This is crazy. I started my computer and just have WIFI turned on. I did as you said launching django and djangorestframework and it installed fine! I have the server running and testing now.

So what should I tell the admin to do since I probably don't have access? Just whitelist pypi etc?

If you guys are adopting Django for development on organization level then it's a good idea to whitelist pypi to save others from trouble. If you're the only one working with it and nothing else is causing any problem then probably you can skip it for now.
