我如何调试“错误:产卵ENOENT”在node.js?

当我得到以下错误:

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: spawn ENOENT
    at errnoException (child_process.js:1000:11)
    at Process.ChildProcess._handle.onexit (child_process.js:791:34)

我该采取什么程序来修理呢?

作者注:这个错误的许多问题鼓励我发布这个问题，以供将来参考。

当前回答

简单地添加shell: true选项解决了我的问题:

不正确的:

const { spawn } = require('child_process');
const child = spawn('dir');

正确的:

const { spawn } = require('child_process');
const child = spawn('dir', [], {shell: true});

其他回答

对我来说，我在package.json中做了以下更改。

  "version": "0.0.0",
  "scripts": {
    "dev": "vite --open",    // delete this line
    "dev": "vite",           // with this one
   .....
  }

对于Windows上的ENOENT, https://github.com/nodejs/node-v0.x-archive/issues/2318#issuecomment-249355505修复它。

如更换产卵(npm, [' v '], {stdio:“继承”}):

对于所有node.js版本: 产卵(/ ^赢/ test (process.platform) ?npm。Cmd ': 'npm'， ['-v']， {stdio: 'inherit'}) 对于node.js 5。X及以后: 产卵(npm, [' v '], {stdio:“继承”,外壳:真})

我在windows 8上得到了同样的错误。问题是由于系统路径的环境变量丢失。将“C:\Windows\System32\”值添加到系统PATH变量中。

使用要求(“child_process”)。Exec代替产卵更具体的错误消息!

例如:

var exec = require('child_process').exec;
var commandStr = 'java -jar something.jar';

exec(commandStr, function(error, stdout, stderr) {
  if(error || stderr) console.log(error || stderr);
  else console.log(stdout);
});

试了所有的都没用，我的系统有不同的问题。

我的解决方案是运行命令: C:\Program Files\git\bin\bash.exe
