I'm trying to install ROS from source.
When I execute the command of installation, I get such an error:

I don't know how to solve this issue. Maybe it's because I worked behind a proxy? If so, how to make urllib.urlretrieve work behind the proxy?
Add proxy settings to your global environment to see if it fixes the problem.
sudo gedit /etc/environment
Then add these two lines
http_proxy=http://your_proxy.com:443
https_proxy=https://your_proxy.com:443

What seems to be the problem?
PD: I'm using a late 2014 MacMini with Monterey OS.
I got this solved. It seemed the error had to do with python certificates.
In macOS just open Macintosh HD
Now Select Application
Then Select Python folder (Python3.6, Python3.7 Whatever You are using just select this folder)
Then, double click on Install Certificates.command.
Now your error should be solved.

Also my code is :

def downloadWebImage(url):
name = random.randrange(1,1000)
fullName = str(name) + '.jpg'
urllib.urlretrieve(url, fullName)
downloadWebImage("https://qph.ec.quoracdn.net/main-qimg-601accaf841bba9145d3c46bece1ea10-p")
So what are the errors, why are they occuring? What is their fix?
i'm just getting started with spaCy under python. Sadly I'm already stuck at installation process (https://spacy.io/docs/#getting-started).

Somebody got a similar err?
The problem was caused by a serverproblem of spacy itself and is fixed now.
