pdm not working on macOS 15.0

[marswong]

• [x] I have searched the issue tracker and believe that this is not a duplicate.

Make sure you run commands with -v flag before pasting the output.

Steps to reproduce

1. install pdm through brew install pdm on macOS 15.0
2. run pdm self update -v

Actual behavior

Run this small snippet and see if that produces error:

import truststore, certifi, ssl

ctx = truststore.SSLContext(ssl.PROTOCOL_TLS_CLIENT)
cert_path = certifi.where()
print(cert_path)
ctx.load_verify_locations(cert_path)

Run this small snippet and see if that produces error:

import truststore, certifi, ssl

ctx = truststore.SSLContext(ssl.PROTOCOL_TLS_CLIENT)
cert_path = certifi.where()
print(cert_path)
ctx.load_verify_locations(cert_path)

I cannot install truststore using my default python version 3.9.19, but it works fine if I switch to 3.12.6 using pyenv.

[frostming]

run that in the same environment of pdm

run that in the same environment of pdm

same as the error logs above:

does the cert_path exist? and anyway it proves not a problem of pdm

[marswong]

Yes, but the cacert.pem is a blank file, is it expected? So how can I fix this, it worked before upgrading to macOS 15.0

[frostming]

try reinstalling the forluma with homebrew
