generic

中文

指定的命令未安装或不在系统的PATH环境变量中。

Workarounds

  1. 95% success Use exec.LookPath to find command before execution 
    path, err := exec.LookPath("command")
if err != nil { return fmt.Errorf("command not found: %w", err) }
cmd := exec.Command(path, args...)

Dead Ends

Common approaches that don't work:

  1. Hardcoding full path to executable 60% fail

    Path may differ across systems; use exec.LookPath to verify.
