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

在我的情况下,删除节点,删除所有AppData/Roaming/npm和AppData/Roaming/npm-cache,并安装节点再次解决问题。

其他回答

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']);

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);
});

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。

我的解决方案

var spawn = require('child_process').spawn;

const isWindows = /^win/.test(process.platform); 

spawn(isWindows ? 'twitter-proxy.cmd' : 'twitter-proxy');
spawn(isWindows ? 'http-server.cmd' : 'http-server');

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。
