       exec('./uli.bat', function (err, data) {
        console.log(err);

4 个解决方案

I have found the solution for it.. and its works fine for me. This opens up a new command window and runs my main node JS in child process. You need not give full path of cmd.exe. I was making that mistake.

我已经找到了解决的办法。它对我来说很好。这将打开一个新的命令窗口，并在子进程中运行我的主节点JS。你不需要给出cmd.exe的完整路径。我犯了那个错误。

var spawn = require('child_process').spawn,
ls    = spawn('cmd.exe', ['/c', 'my.bat']);

ls.stdout.on('data', function (data) {
console.log('stdout: ' + data);
});

ls.stderr.on('data', function (data) {
console.log('stderr: ' + data);
});

ls.on('exit', function (code) {
console.log('child process exited with code ' + code);
});

The easiest way I know for execute that is following code :

我知道的最简单的执行方法是:

require('child_process').exec("path/to/your/file.bat", function (err, stdout, stderr) {
    if (err) {
        // Ooops.
        // console.log(stderr);
        return console.log(err);
    }

    // Done.
    console.log(stdout);
});

You could replace "path/to/your/file.bat" by __dirname + "/file.bat" if your file is in the directory of your current script for example.

你可以取代“路径/ / /文件。用" __dirname + "/file打。如果你的文件在当前脚本的目录中。

In windows, I don't prefer spawn as it creates a new cmd.exe and we have to pass the .bat or .cmd file as an argument.'exec' is better option. Example below:

在windows中，我不喜欢衍生，因为它创建了一个新的cmd。exe和我们必须传递。bat或。cmd文件作为参数。“执行”是更好的选择。在下面的例子:

Please note that in windows you need to pass path with double \ e.g. C:\path\batfilename.bat

请注意，在windows中，你需要用双\ C:\path\batfilename.bat传递路径

const { exec } = require('child_process');
exec("path", (err, stdout, stderr) => {
  if (err) {
    console.error(err);
    return;
  }
  console.log(stdout);
});

An easier way I know for executing that is the following code :

我知道一种更简单的执行方法是下面的代码:

function Process() {
const process = require('child_process');   
var ls = process.spawn('script.bat');
ls.stdout.on('data', function (data) {
  console.log(data);
});
ls.stderr.on('data', function (data) {
  console.log(data);
});
ls.on('close', function (code) {
      if (code == 0)
        console.log('Stop');
      else
        console.log('Start');
});
};

Process();

ls.stderr.on('data', function (data) {
