urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1108)

import yfinance as yf

msft = yf.Ticker("MSFT")

msft.info

I tried to print msft.info and got 'urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1108)' error. I tried to rerun the Install Certificates.command and Update Sheet.command but apparently it didn't work. Also after I reran them I got this massage: Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/certifi-2021.5.30.dist-info.

Any advices how can I fix it?

The above solution of Install Certificates.command works but it appears that what it's doing is really just pip install --upgrade certifi.

I've tried this and it works for me

import ssl

ssl._create_default_https_context = ssl._create_stdlib_context

I had the same problem in an virtual environment created with Poetry in Windows. I solved it removing the venv, then reinstalling all the deps.

Here are the steps for macOS:

  1. Open the folder /Applications/Python 3.x (x is the version you are running).
  2. Double click the Install Certificates.command. It will open a terminal and install the certificate.

In my case, I had to do this twice before it worked. Here is a screenshot from the Finder:

If you have error [Errno 13] Permission denied: with InstallCertificates.command, open script in text editor, copy code and run in terminal with sudo su.

This answer got me from 2nd base home, but it skips over that the full path one would want is /Applications/Python 3.x/Install Certificates.command (which was called out in an other question's answer

(I was initially looking in the folder symlinked from /usr/local/bin/python3)

I had this problem using Anaconda with Python 3.9, and on Windows - the solution for me was in this answer: How to get and save LetsEncrypt certificates on Windows.

The process is:

For this part import the ISRG certs into the 'Certificates/Personal' folder, and import the Let's Encrypt R3 cert into the 'Trusted Root Certification Authorities/Certificates' folder.

  • Restart system.

A quick google search returns the following: http://blog.wafrat.com/fixing-certificate_verify_failed-when-using-yfinances-ticker-info/

As explained in the website linked above, the issue is due to:

It turns out it's because I am running Python on Mac OS and I need to install some certificates (Mac OSX python ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:749)).

And the solution is to:

So I opened Finder and navigated to Applications, Python 3.7, then ran Install Certificates.command. And it worked indeed!
