Npm start 在 Angular 2 和 Laravel 5 项目中不起作用

Question

我正在做一个 Laravel 5.2 和 Angular 2 项目，我刚刚完成 angular 的设置，但是运行 npm start，我出现以下错误：

npm ERR! Windows_NT 6.1.7601
npm ERR! argv "C:\Program Files\nodejs\node.exe" "C:\Program Files\nodejs\node_modules\npm\bin\npm-cli.js" "install"
npm ERR! node v4.4.7
npm ERR! npm  v2.15.8
npm ERR! code ELIFECYCLE
npm ERR! @ postinstall: `typings install`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the @ postinstall script 'typings install'.
npm ERR! This is most likely a problem with the  package,
npm ERR! not with npm itself.
npm ERR! Tell the author that this fails on your system:
npm ERR!     typings install
npm ERR! You can get information on how to open an issue for this project with:
npm ERR!     npm bugs
npm ERR! Or if that isn't available, you can get their info via:
npm ERR!
npm ERR!     npm owner ls
npm ERR! There is likely additional logging output above.

你们能帮帮我吗？

这是我的内容 package.json :

{
  "private": true,
  "scripts": {
    "prod": "gulp --production",
    "dev": "gulp watch",
    "start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite\" ",
    "lite": "lite-server",
    "postinstall": "typings install",
    "tsc": "tsc",
    "tsc:w": "tsc -w",
    "typings": "typings"
  },
  "devDependencies": {
    "gulp": "^3.9.1",
    "laravel-elixir": "^5.0.0",
    "bootstrap-sass": "^3.0.0",
    "concurrently": "^1.0.0",
    "del": "^2.2.0"
  },
  "dependencies": {
    "angular2": "2.0.0-beta.0",
    "bootstrap-sass": "^3.0.0",
    "elixir-typescript": "^1.1.2",
    "es6-promise": "^3.0.2",
    "es6-shim": "^0.33.3",
    "laravel-elixir": "^4.0.0",
    "reflect-metadata": "0.1.2",
    "rxjs": "5.0.0-beta.0",

Answer 1

我也遇到这个问题，我按照以下步骤操作

 1. i uninstall nodejs and install the latest version.
 2. close the command promt and open.
 3. execute npm install
 4. execute npm build(not nesessery) 
 5. execute npm start

这对我有用。

Answer 2

您的脚本在尝试运行 'typings install' 时失败。
1. 在 devDependencies

中包含类型

{
  "devDependencies": {
    "concurrently": "^2.0.0",
    "lite-server": "^2.2.0",
    "typescript": "^1.8.10",
    "typings": "^1.0.4"
  }
}

运行 npm 安装

如下创建typings.json

{
  "globalDependencies": {
    "core-js": "registry:dt/core-js#0.0.0+20160602141332",
    "jasmine": "registry:dt/jasmine#2.2.0+20160621224255",
    "node": "registry:dt/node#6.0.0+20160807145350"
  }
}

npm 启动

if you still having issue install typings globally npm install typings --global

Npm start 在 Angular 2 和 Laravel 5 项目中不起作用
