Question

我正在开发一个Laravel 5.2和Angular 2项目，我刚刚完成角度设置但是在运行npm start时，我收到以下错误：

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.

你能帮助我吗？

这是我的package.json：

的内容

{
  "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",

  },
  "dependencies": {

    "zone.js": "0.5.10"
  }
}

Answer 1

尝试运行＆＃39; typings install＆＃39;时，您的脚本失败了。
1.在devDependencies中包含输入法

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

运行npm install

创建typings.json，如下所示

{
  "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 start

如果您仍然在全球范围内遇到安装问题 npm install typings --global

Answer 2

我也面临这个问题，我会执行以下步骤

 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

这适合我。

Npm start在Angular 2和Laravel 5项目中不起作用
