Environment Differences
Homebrew, pyenv, nvm: PATH Ordering and KERNEL PANIC
KERNEL PANIC results from PATH ordering conflicts between Homebrew, pyenv, nvm, rbenv, and the system versions of each tool.
The shell initializes PATH in order: /etc/paths, /etc/paths.d/ files, then your shell profile (~/.zprofile, ~/.zshrc). Each version manager prepends its shim directory to PATH to intercept the commands. If initializations happen in the wrong order or one manager is not initialized, the wrong binary is invoked and KERNEL PANIC results. Verify the active interpreter with which python3, which node, which ruby and compare the paths against echo $PATH. For zsh (macOS default since Catalina), initialization order is ~/.zprofile (login shells) then ~/.zshrc (interactive shells) — source version manager initializations in ~/.zprofile to ensure they run in terminal, VS Code integrated terminal, and GUI applications that spawn shells. Run env -i zsh -l -c 'which python3' to test what a fresh login shell resolves without your current environment.Optional follow-up
