getting a Certificate Verify Failed issue #158

Open

Description

@Mnemnosine

I'm trying to download Poetry onto my Mac using [curl -sSL https://install.python-poetry.org | python3 -] and I'm getting the following error code:

urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1028)>

Somewhere there's a certificate verification failing, and I don't have the skills necessary to be able to figure it out as I'm just a Python newbie.

    You need to install the certificates first. Should be something along the lines of:

     open "/Applications/Python 3.12/Install Certificates.command"

    You know what's actually unexpectedly awesome about this? That I didn't give up on python and now my skills are at the point where I know what you're referencing and how to actually fix this. Thank you, kind internet stranger! :-D
