codex cli has been out for 5 months with 170k weekly downloads - it's definitely 'ready for primetime' if you can get past your bug. I don't have that issue.

The install errors out after following two basic install commands. This is poor code hygiene on the part of the authors. That's "not ready for primetime" in my book.

Please tell me you are not running a NodeJS release that hasn't been supported for at least 3 years...

Optional chaining was added in v14 (2020), and it sure looks like that is the issue here.

Brand new, clean install of npm.

Poor code + doc hygiene is the problem here.

The question is which version of node, not npm.
