Go 如何将 npm 安装进度条通过管道传输到终端

我试过使用stdoutpipe and stderrpipe，如下所示.

shell := exec.Command("npm", args...)
shell.Dir = cwd

outpipe, _ := 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)
}

However I only get output:个

当您从控制台运行NPM Install时，如何获得安装进度条？

我也try 过使用类似下面的解决方案，并在运行shell.run()后打印缓冲区，但它也会产生与上面相同的输出.

shell := exec.Command(command, args...)
shell.Dir = cwd
var stderr, stdout bytes.Buffer

shell.Stderr = &stderr
shell.Stdout = &stdout

return shell, &stdout, &stderr
