'SSLError' installing with pip

Question

I'm trying to install Django on a Windows 10 system.

Whatever I try to install with pip on cmd, I get these 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

your firewall is not allowing pip to connect to internet, so allow pip from the windows firewall and it will work — Exprator, Jun 17 '19 at 09:13
make sure that you have strong internet connection and allow firewall to connect to pip **refer this** https://github.com/pypa/pip/issues/6152 — rahul.m, Jun 17 '19 at 09:15
@Exprator The internet connection isn't a problem so it's probably the company's firewall and I don't think I can allow it myself. Is there another way to install django? — yannm, Jun 17 '19 at 09:36
Doing a trace route might shed some light on where it is being block. From `cmd`, try `tracert pypi.python.org`. If you see an address with `*` displayed, that means it can't reach that hop point. — FlipperPA, Jun 17 '19 at 10:52
@FlipperPA I have indeed * displayed so I guess it can't reach ....This is probably because of the company's firewall and I tried some commands with proxy but nothing seems to works — yannm, Jun 17 '19 at 11:53
If you're using a VPN, it may be best to disable it first. This is what worked for me. — NelsonGon, Dec 21 '20 at 05:38

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

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"

WOW. It really worked - use http instead of https for HTTPS_PROXY – arturro Jan 15 '21 at 15:16
Working. Just also created an environmental variable with the proxy I am using. No need to not upgrade to pip to 20.3.1. – skinnyas123 Feb 02 '21 at 01:46

just in case someone gets here, in powershell, this worked for me: ```$env:HTTPS_PROXY = "http://proxy:port" $env:https_proxy = "http://proxy:port"``` – user3322417 Oct 20 '21 at 15:28
This works, but does it have any security implications if https traffic uses a http proxy? – gerrit Dec 17 '21 at 09:19
In what file does it go? – Peter Mortensen Feb 04 '22 at 18:11
In the file you define your environment variables. It's OS and shell dependent – Roy van Santen Feb 04 '22 at 19:29

My pip was working fine (Windows 7 and Python 3.8.6) until I upgraded pip from version 20.2.1 to 20.3.1, after which I also got the error:

SSL: WRONG_VERSION_NUMBER error.

This is reproducible. I uninstalled and reinstalled several times to confirm.

Solution (well, workaround): don't upgrade pip to 20.3.1.

Note: pip 20.3.1 works fine in my Windows 7/Python 3.9.1 environment.

I found by trial and error that 20.2.4 was the highest version that works for me with python 3.7.9 – James Feb 04 '21 at 15:02
I also ran into this issue with a fresh install of Python 3.9.1 on Win10 and upgrade to pip 21.0.1. Solution was to reinstall Python and stay with pip on version 20.2.3. We have a SSL Interception Proxy and i tried to set global.cert which seems not to be used by pip 21.0.1. I filed an issue: https://github.com/pypa/pip/issues/9614 – Martin Feb 16 '21 at 16:29
@LuciusSilanus How you solve your problem, may you share ? – ugurtosun Mar 31 '21 at 11:03
@UğurGürkanTosun I had to download a wheel for pip 20.2.4 and install it from the wheel file (https://stackoverflow.com/a/28002930/4871972) – Lucius Silanus Apr 03 '21 at 21:44

I asked a colleague who automatically knew what to do. I just had to set the proxy variables:

set https_proxy=http://username:password@proxy.example.com:8080
set http_proxy=http://username:password@proxy.example.com:8080

and it works.

Setting in what context? In some batch file? Directly on the command line before some install steps? Something else? Please respond by [editing (changing) your answer](https://stackoverflow.com/posts/56649266/edit), not here in comments (***without*** "Edit:", "Update:", or similar - the answer should appear as if it was written today). – Peter Mortensen Feb 04 '22 at 18:06

Check your proxy setting. You can use this command

pip install <package> --trusted-host pypi.org --trusted-host files.pythonhosted.org --proxy="<IP>:<port>"

I still have this error : " Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ConnectTimeoutError(, 'Connection to 192.168.0.254 timed out. (connect timeout=15)')': /simple/django/" – yannm Jun 17 '19 at 11:55

This command works fine `pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org --proxy="http://:@:"` – NaveenKumar Namachivayam Dec 10 '19 at 19:33
Worked for me as well. Thanks!! – Ashlin Karkada Apr 10 '20 at 05:17

For me it was the system proxy. The trusted-host flag, to my knowledge, is used when pip wants to query an insecure http index and pip defaults to query only SSL secured indexes.

Try finding and removing OpenSSL (OS level installation), if it's installed on your system.

In my case, I installed OpenSSL on Windows 10 (for some other development tasks) long time ago and forgot about it, which was the main culprit. I uninstalled it, and it solved the issue.
