version 0.22.0 replaces the web server implementation, so this issue no longer arises. Could you try
npm -g i @openai/codex@latest?I have updated to latest and I still get this error Address in use (os error 98). I am using codex in VsCode at the same time
I no longer get this issue in the latest version of Codex and have since switched to native. Thanks!
What version? Have you tried native?
npm -g i @openai/codex@nativehas been working fine for me.edit: should also mention I upgraded my WSL2 instance to Ubuntu 24.04 since attempting to get Codex working with my subscription.
I tried, but it requires a Git repo or so it seems. What I want is to use the CLI giving it permissions to use my actual computer. For repo use I'm using codex on Vscode
