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

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');
})();

最近我也遇到了类似的问题。

Starting the development server...

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

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。

对于任何可能偶然发现这一点的人来说，如果所有其他答案都没有帮助，并且你是在Windows上，知道当前Windows上的spawn和patheext环境变量有一个大问题，可以导致某些调用spawn不能工作，这取决于目标命令的安装方式。

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});

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);
});
