typescript Angular 2：如何正确自动导入 normalize.css

Angular 2: How to correctly automatically import normalize.css

提问by Garfield550

I am a new Angular 2 user, and I have some problems with it.

我是一个新的 Angular 2 用户，我遇到了一些问题。

Traditionally, we could use <link rel="stylesheet" href="node_modules/normalize.css/normalize.css" />to import a css file, but I want to make Angular 2 to automatically import it using import.

传统上，我们可以<link rel="stylesheet" href="node_modules/normalize.css/normalize.css" />用来导入一个 css 文件，但我想让 Angular 2 使用import.

I tried to use the same way when I used Material 2:

当我使用材料 2 时，我尝试使用相同的方式：

// angular-cli-build.js

module.exports = function(defaults) {
  return new Angular2App(defaults, {
    vendorNpmFiles: [
      'normalize-path/index.js',
    ]
  });
};

// system-config.ts 

const map: any = {
  'normalize': 'vendor/normalize-path',
};

/** User packages configuration. */
const packages: any = {
  'normalize': {main: 'index.js'},
};

// app.component.ts

import { normalize } from 'normalize-path';

The editor will complain:

编辑会抱怨：

Cannot find module 'normalize-path'.

找不到模块“规范化路径”。

And the code won't compile. But I really have no idea what was wrong.

并且代码不会编译。但我真的不知道出了什么问题。

Update for Angular 8

Angular 8 更新

1. Install the normalize.css library:

   npm install --save normalize.css
   

2. Import it in your styles.css

   @import '~normalize.css';
   

1. 安装 normalize.css 库：

   npm install --save normalize.css
   

2. 将它导入你的styles.css

   @import '~normalize.css';

With the current (1.0.0-beta.15) version of angular-cli, the solution is quite easy:

使用当前 ( 1.0.0-beta.15) 版本的 angular-cli，解决方案非常简单：

1. npm i normalize.css
2. add "../node_modules/normalize.css/normalize.css"in apps[0].stylesin the config file angular-cli.json

1. npm i normalize.css
2. 添加"../node_modules/normalize.css/normalize.css"在apps[0].styles在配置文件angular-cli.json

Note:If using Angular 7, the config file is now angular.json, and the path to normalise.css in apps[0].stylesshould be "../node_modules/normalize.css/normalize.css".

注意：如果使用 Angular 7，配置文件现在是angular.json，并且 normalise.css 的路径apps[0].styles应该是"../node_modules/normalize.css/normalize.css".

Example:

例子：

{
  "project": {
    "version": "1.0.0-beta.15",
    "name": "normalize.css-in-angular2"
  },
  "apps": [
    {
      "root": "src",
      "outDir": "dist",
      "assets": "assets",
      "index": "index.html",
      "main": "main.ts",
      "test": "test.ts",
      "tsconfig": "tsconfig.json",
      "prefix": "app",
      "mobile": false,
      "styles": [
        "../node_modules/normalize.css/normalize.css",
        "styles.css"
      ],
      "scripts": [],
      "environments": {
        "source": "environments/environment.ts",
        "dev": "environments/environment.ts",
        "prod": "environments/environment.prod.ts"
      }
    }
  ],
  "addons": [],
  "packages": [],
  "e2e": {
    "protractor": {
      "config": "./protractor.conf.js"
    }
  },
  "test": {
    "karma": {
      "config": "./karma.conf.js"
    }
  },
  "defaults": {
    "styleExt": "css",
    "prefixInterfaces": false
  }
}

The accepted response doesn't seem to be working on app. I needed to remove the ../in the path name.

接受的响应似乎不适用于应用程序。我需要删除../路径名中的 。

The angular.jsonstyles bit should be something like this:

该angular.json款式位应该是这样的：

"styles": [
    "node_modules/normalize.css/normalize.css",
    "styles.css"
  ],

// angular-cli-build.js

module.exports = function(defaults) {
  return new Angular2App(defaults, {
    vendorNpmFiles: [
      'systemjs/dist/system-polyfills.js',
      'systemjs/dist/system.src.js',
      'zone.js/dist/**/*.+(js|js.map)',
      'es6-shim/es6-shim.js',
      'reflect-metadata/**/*.+(ts|js|js.map)',
      'rxjs/**/*.+(js|js.map)',
      '@angular/**/*.+(js|js.map)',
      '@angular2-material/**/*.+(js|js.map)',
      'normalize.css/normalize.css'
    ]
  });
};

and simple add the css link to index.html

并简单地将 css 链接添加到 index.html

// index.html
<link href="vendor/normalize.css/normalize.css" rel="stylesheet">
