o4-mini

What platform is your computer?

darwin | arm64 | 24.4.0

What steps can reproduce the bug?

```

2 reasoning | 1 tool

What is the expected behavior?

That it respects my rbenv path. It looks like seatbelt might be overriding the PATH which forces the system ruby.

What do you see instead?

 /usr/local/bin:/System/Cryptexes/App/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/local/bin:/var/run/com.apple.security.cryptexd/codex.system/boots
    trap/usr/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/appleinternal/bin:

(stripped my personal paths at the end there)

Additional information

Happy to solve this another way, the goal is just to be able to us the proper ruby here.

This isn't a good solution, but for now you can have it run eval "$(rbenv init -)"; COMMAND GOES HERE

I put the following in my ~/.codex/instructions.md and it seems to work fine for now.

Add this to the front of any shell command. It will ensure that rbenv is loaded and the correct Ruby version is used.

`eval "$(rbenv init - zsh)";`

Can we configure bash profile for codex?

I searched documents and found:

~We can set environment variables as configuration~
Update: It didn't work in my environment. Maybe its also a bug?
Environment:
Linux 6.10.14-linuxkit aarch64 unknown
It is a docker container on macOS Darwin 24.5.0 arm64 arm
PATH should be inherited by default. So this issue is labelled as a bug.
