我们想在angular-cli 1.0.0-beta.5生成的应用程序中使用bootstrap 4 (4.0.0-alpha.2)(w/ node v6.1.0)。

在获得bootstrap及其对npm的依赖之后,我们的第一个方法是将它们添加到angular-cli-build.js中:

'bootstrap/dist/**/*.min.+(js|css)',  
'jquery/dist/jquery.min.+(js|map)',  
'tether/dist/**/*.min.+(js|css)',

然后导入到index。html中

<script src="vendor/jquery/dist/jquery.min.js"></script>
<script src="vendor/tether/dist/js/tether.min.js"></script>
<link rel="stylesheet" type="text/css" href="vendor/bootstrap/dist/css/bootstrap.min.css">
<script src="vendor/bootstrap/dist/js/bootstrap.min.js"></script>

这在ng serve中工作得很好,但当我们生成一个带有-prod标志的构建时,dist/vendor中的所有依赖项都消失了(惊讶!)

我们打算如何处理这样的场景(即加载引导脚本)在一个用angular-cli生成的项目?

我们有以下想法,但我们真的不知道该怎么做……

use a CDN ? but we would rather serve these files to guarantee that they will be available copy dependencies to dist/vendor after our ng build -prod ? But that seems like something angular-cli should provide since it 'takes care' of the build part ? adding jquery, bootstrap and tether in src/system-config.ts and somehow pull them into our bundle in main.ts ? But that seemed wrong considering that we are not going to explicitly use them in our application's code (unlike moment.js or something like lodash, for example).

试试这个

npm install bootstrap@next

对于bootstrap 4.5, angular 10

npm install bootstrap --save

更新你的风格。这样的SCSS带有bootstrap import语句。

 $theme-colors: (
    "primary":    #b867c6,
    "secondary":  #f3e5f5,
    "success":    #388e3c,
    "info":       #00acc1,
    "light":      #f3e5f5,
    "dark":       #863895
);

@import "~bootstrap";

@import url('https://fonts.googleapis.com/css2?family=Raleway&display=swap');

body {
    color: gray('800');
    background-color: theme-color('light');
    font-family: 'Raleway', sans-serif;
}

导入引导应该在变量覆盖之后。[这个例子还展示了如何放置自己的主题颜色。]

首先,你必须用这些命令安装tether, jquery和bootstrap

npm i -S tether
npm i -S jquery
npm i -S bootstrap@4.0.0-alpha.4 

在你的angular-cli中添加这些行。json(角。Json从版本6起)文件

  "styles": [
    "styles.scss",
    "../node_modules/bootstrap/scss/bootstrap-flex.scss"
  ],
  "scripts": [
    "../node_modules/jquery/dist/jquery.js",
    "../node_modules/tether/dist/js/tether.js",
    "../node_modules/bootstrap/dist/js/bootstrap.js"
  ]

安装助推器

NPM install -save bootstrap

然后我们需要导入Bootstrap Sass到我们的应用程序中。在风格。SCSS添加这一行:

@ import“. . / node_modules /引导/ scss / bootstrap.scss”;

欲了解更多信息…

安装引导程序,popper.js

NPM install -save bootstrap 保存popper.js

在src/styles.css中导入bootstrap的样式

@import '~bootstrap/dist/css/bootstrap.min.css';

Install bootstrap using npm i --save bootstrap@version.Now,go to nodemodules folder and from bootstrap folder copy the path of 'bootstrap.min.css.js' and paste the full path(like nodemodules/bootstrap/css/bootstrap.min.css.js) in angular.json under script tag file and re-run the server and to check whether the installation is successful run the program in any browser you like and press F12 you'll find a part of the window gets opened,now go to elements tab open head tag and if you see bootstrap in style tag,then your installation is successful.
