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

我也遇到了同样的问题，但我找到了一个简单的解决方法。如果程序已经被用户添加到PATH(例如，正常的系统命令工作)，它似乎是spawn()错误。

要解决这个问题，你可以使用which模块(npm install——save which):

// Require which and child_process
const which = require('which');
const spawn = require('child_process').spawn;
// Find npm in PATH
const npm = which.sync('npm');
// Execute
const noErrorSpawn = spawn(npm, ['install']);

其他回答

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。

正如@DanielImfeld指出的那样，如果你在选项中指定了“cwd”，但是给定的目录不存在，ENOENT将被抛出。

将C:\Windows\System32\添加到path环境变量。

步骤

进入我的电脑和属性点击高级设置然后是环境变量选择Path，然后单击edit 如果不存在，则粘贴以下文件:C:\Windows\System32\ 关闭命令提示符运行您想要运行的命令

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
   .....
  }

最近我也遇到了类似的问题。

Starting the development server...

events.js:174
      throw er; // Unhandled 'error' event
      ^

Error: spawn null ENOENT
    at Process.ChildProcess._handle.onexit (internal/child_process.js:240:19)
    at onErrorNT (internal/child_process.js:415:16)
    at process._tickCallback (internal/process/next_tick.js:63:19)
Emitted 'error' event at:

    at process._tickCallback (internal/process/next_tick.js:63:19)
error Command failed with exit code 1.

这是由于浏览器的.env文件中有一个错误的配置。我有BROWSER=null，但它必须是BROWSER=none。改变配置解决了我的问题。
