I want to install Ruby 3.3.3 on macOS Sonnoma 14.4.1 (23E224) using asdf:

Any idea what could cause this? I'll try to update to 14.5 later this day, but so far I'm stuck at work here.

Turns out, my .gemrc had a formatting, that the new Psych parser didn't like. I had to change it:

old:

gem: --no-document
:sources:
- s3://custom-gems
- https://rubygems.org/
s3_source: {
  custom-gems: {
    id: "XXXXXXXXXX",
    secret: "XXXXXXXX",
    region: "eu-central-1"
  }
}

new:

gem: --no-document
:sources:
  - s3://custom-gems
  - https://rubygems.org/
s3_source:
  custom-gems:
    id: "XXXXXXXXXX"
    secret: "XXXXXXXX"
    region: "eu-central-1"
