Making Codex CLI and Codex.app Use mise-managed Ruby and Node.js
The article discusses how to configure Codex CLI and Codex.app to utilize mise-managed Ruby and Node.js. The author encountered issues due to Codex's sandboxed environment, which prevented the proper loading of environment variables. A solution was found by modifying the ~/.zshenv file to include mise shims in the PATH for non-interactive shells.
- ▪The author primarily uses Codex CLI and Codex.app on macOS.
- ▪Codex's command execution environment operates within a sandbox, which restricts certain functionalities.
- ▪The solution involved adding mise shims to the PATH in the ~/.zshenv file to ensure proper environment variable loading.
