当我尝试cmd.exe通过以下代码开始时：

use std::process::{Command, Stdio};
use std::io::{BufRead, Write, BufReader};

fn main() {
    let mut child_cmd = Command::new("cmd.exe")  
        // seems it work well with `/bin/bash` in Linux
        .stdin(Stdio::piped())
        .stdout(Stdio::piped())   // Error emitted here. 
        .spawn()
        .unwrap();   
    // do sth. else
}

我想将输出重定向到管道，但它总是报告The process tried to write to a nonexistent pipe；当我删除时.stdout(Stdio::piped())，没有抛出错误。为什么会发生这种情况？
