During handling of the above exception, another exception occurred:

There is a suggestion to run Install Certificates.command: certificate verify failed: unable to get local issuer certificate But I can't find this file in the python location or anywhere else on my computer.

Solution

  • I managed it by using pip (from powershell): pip install poetry
