如何将 npm 安装进度条通过管道传输到终端？

Question

我试过使用stdoutpipe 和 stderrpipe，如下所示。shell := exec.Command("npm", args...)shell.Dir = cwdoutpipe, _ := shell.StdoutPipe()errpipe, _ := shell.StderrPipe()shell.Start()go func(pipe io.ReadCloser) {    reader := bufio.NewReader(pipe)    line, err := reader.ReadString('\n')    for err == nil {        fmt.Println(string(line))        line, err = reader.ReadString('\n')    }    fmt.Println("exited")}(outpipe)go func(pipe io.ReadCloser) {    reader := bufio.NewReader(pipe)    line, err := reader.ReadString('\n')    for err == nil {        fmt.Println(string(line))        line, err = reader.ReadString('\n')    }    fmt.Println("exited")}(errpipe)err := shell.Wait()if err != nil {    fmt.Println(err)}但是我只得到输出：added 87 packages, and audited 88 packages in 3s9 packages are looking for fundingrun `npm fund` for detailsfound 0 vulnerabilities如何获取从控制台运行 npm install 时获得的安装进度条？我也尝试过使用下面的解决方案并在运行 shell.run() 后打印缓冲区，但它也提供与上面相同的输出。shell := exec.Command(command, args...)shell.Dir = cwdvar stderr, stdout bytes.Buffershell.Stderr = &stderrshell.Stdout = &stdoutreturn shell, &stdout, &stderr

Answer 1

cmd := exec.Command("npm", args...)

cmd.Dir = cwd

cmd.Stdout = os.Stdout

cmd.Stderr = os.Stderr

重定向到os 的 stdout 和 stderr就是诀窍。
