Having the same issue, using nvm, even in full-approval mode still not able to use npm/node commands or go commands. doesn't ask for approval just fails.
Having the same issue, “Operation not permitted” when "mvn -q -DskipTests compile"
Same here,
npm: command not found.In fact, no programs installed with npm are available to codex. I've tried different options for
