我有一个由
开发的项目 yarn start
它运行一个index.js
,启动一个grunt进程并收到此错误:
$ yarn start
yarn start v0.23.2
$ node ./development
grunt_arguments [ '--force', '--notify', '--verbose', '--debug', '--stack' ]
=======================================
Open http://localhost:8000 to start developing
events.js:141
throw er; // Unhandled 'error' event
^
Error: spawn ./node_modules/.bin/grunt ENOENT

不知道它能是什么。环境是:
答案 0 :(得分:2)
我经常使用补丁child_process
来帮助我调试这类问题。在index.js
文件的开头添加类似的内容:
const util = require('util')
const childProcess = require("child_process");
const originalSpawn = childProcess.spawn;
childProcess.spawn = function() {
console.trace('SPAWN');
console.log('ARGS');
console.log(util.inspect(arguments, false, null)); // showHidden = false, depth = null
return originalSpawn.apply(this, arguments);
};
如果你的跑步childProcess.spawn('ls', ['-lh', '/usr'])
,你会看到类似的内容:

ARGS

也许在运行之后,您可以使用新信息更新您的问题。
