Could not fetch URL

Question

This is not a duplicate. I've read every response there is online.

Any time I try to connect to a website through the terminal I get an error. Many solutions say to try installing certifi first and then attempting, but I can't do that either because then I'd have to connect to https://pypi.python.org/simple/certifi/. I've also tried --trusted-hostbut I still receive an error.

Here is the error if I try to run the Install Certificates.command in the Python 3.6 folder:

/Applications/Python\ 3.6/Install\ Certificates.command ; exit; -- pip install --upgrade certifi Collecting certifi Could not fetch URL https://pypi.python.org/simple/certifi/: There was a problem confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:777) - skipping Could not find a version that satisfies the requirement certifi (from versions: ) No matching distribution found for certifi Traceback (most recent call last): File "<stdin>", line 44, in <module> File "<stdin>", line 25, in main File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/subprocess.py", line 291, in check_call raise CalledProcessError(retcode, cmd) subprocess.CalledProcessError: Command '['/Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6', '-E', '-s', '-m', 'pip', 'install', '--upgrade', 'certifi']' returned non-zero exit status 1. logout Saving session... ...copying shared history... ...saving history...truncating history files... ...completed. [Process completed]

I also get the SSL error if I try to use url lib to connect in a python doc and then attempt to run the python doc in the terminal. Let me also mention this is a brand new issue. I ran the same script yesterday and it worked fine.

Versions:

Python 3.6 numpy==1.13.3 ortools==6.6.4656 pandas==0.21.0 protobuf==3.5.0.post1 python-dateutil==2.6.1 pytz==2017.3 six==1.11.0 OpenSSH_7.4p1, LibreSSL 2.5.0

Add Below lines in your script and execute the script. Might be it will solve your issue.

import ssl ssl._create_default_https_context = ssl._create_unverified_context

That worked! Can you explain a little what that does? Also is there a way to get this to work in the terminal for things like installing packages?

When your requests verifies SSL certificates for HTTPS requests, just like a web browser. By default, SSL verification is enabled, and Requests will throw a SSLError if it's unable to verify the certificate.

Ok. Any thought on getting it to work in the terminal? If I try to run pip3 install certifi I will still get the same error.

This is extremely dangerous as it disables all network security in your program. Don't do it!
