Were you able to run 0.104.0 on your system? I'm trying to determine if this was a regression in 0.105.0.
Yes, I am even able to run 0.105.0-alpha.26
The big difference is how I install:
npm install -g https://github.com/openai/codex/releases/download/rust-v0.105.0-alpha.26/codex-npm-0.105.0-alpha.26.tgz
vs
npm install -g @openai/codex@latest
Hope this helps.
Well now it works after regressing to the alpha version and then reinstalling the latest
