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?

当前回答

在花费大量时间调试这个问题之前,大多数情况下可以通过删除node_modules并重新安装包来解决。

如何安装:

如果存在锁文件,您可以使用

yarn install --frozen-lockfile

or

npm ci

各自的。如果不是的话

yarn install

or

npm i

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
   .....
  }

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。

虽然对某些人来说这可能是一个环境路径或其他问题,但我刚刚在Windows 10上为Visual Studio Code安装了Latex Workshop扩展,并在尝试构建/预览PDF时看到了这个错误。作为管理员运行VS Code为我解决了这个问题。

我在Windows上遇到了这个问题,用完全相同的命令(省略参数)调用exec和spawn对于exec来说工作得很好(所以我知道我的命令在$PATH上),但spawn会给出ENOENT。原来我只需要将.exe附加到我正在使用的命令:

import { exec, spawn } from 'child_process';

// This works fine
exec('p4 changes -s submitted');

// This gives the ENOENT error
spawn('p4');

// But this resolves it
spawn('p4.exe');
// Even works with the arguments now
spawn('p4.exe', ['changes', '-s', 'submitted']);

Windows解决方案:用节点交叉生成替换生成。例如,在你的app.js的开头:

(function() {
    var childProcess = require("child_process");
    childProcess.spawn = require('cross-spawn');
})();
