events.js:154 抛出错误； // 未处理的“错误”事件 [重复]

Question

创建 Angular 2 应用程序时出现错误。我关注link 创建示例应用程序。当我跑步时

npm start 

我收到以下错误，

events.js:154
   throw er; // Unhandled 'error' event
   ^

Error: watch node_modules/weinre/web/weinre/target/WiRuntimeImpl.amd.js ENOSPC

我得到了这样的 npm 日志，

 npm

   There is likely additional logging output above.

  npm ERR! Please include the following file with any support request:

  npm run lite exited with code 1

我如何解决这个问题？

Answer 1

这意味着您已经运行了该应用程序，然后您尝试再次运行它而不停止最后一次运行。因此，发生了冲突。您必须停止上次运行 单击停止按钮（调试面板上的红色方形按钮）。

Answer 2

我以前的package.json 是，

 {
  "name": "angular2-quickstart",
  "version": "1.0.0",
  "scripts": {
    "start": "concurrently \"npm run tsc:w\" \"npm run lite\" ",    
    "tsc": "tsc",
    "tsc:w": "tsc -w",
    "lite": "lite-server",
    "typings": "typings",
    "postinstall": "typings install" 
  },
  "license": "ISC",
  "dependencies": {
    "angular2": "2.0.0-beta.8",
    "systemjs": "0.19.22",
    "es6-promise": "^3.0.2",
    "es6-shim": "^0.33.3",
    "reflect-metadata": "0.1.2",
    "rxjs": "5.0.0-beta.2",
    "zone.js": "0.5.15"
  },
  "devDependencies": {
    "concurrently": "^2.0.0",
    "lite-server": "^2.1.0",
    "typescript": "^1.8.2",
    "typings":"^0.6.8"
  }
}

我这样添加到package.json，

{
  "name": "angular2-quickstart",
  "version": "1.0.0",
  "scripts": {
    "start": "concurrently \"npm run tsc:w\" \"npm run http\" ",    
    "tsc": "tsc",
    "tsc:w": "tsc -w",
    "http": "http-server -p 3000 -a 127.0.0.1 -o",
    "typings": "typings",
    "postinstall": "typings install" 
  },
  "license": "ISC",
  "dependencies": {
    "angular2": "2.0.0-beta.8",
    "systemjs": "0.19.22",
    "es6-promise": "^3.0.2",
    "es6-shim": "^0.33.3",
    "reflect-metadata": "0.1.2",
    "rxjs": "5.0.0-beta.2",
    "zone.js": "0.5.15"
  },
  "devDependencies": {
    "concurrently": "^2.0.0",
    "http-server": "^0.9.0",
    "typescript": "^1.8.2",
    "typings":"^0.6.8"
  }
} 

现在项目工作查找。

只有 lite ==> http 有变化，然后工作查找
