vue-cli引入BootstrapVue，修改/新增主题变量，定义/应用全局样式

官方文档：Getting Started | BootstrapVue

1. 安装bootstrap、popper.js、portal-vue、bootstrap-vue：

npm i [email protected]
npm i @popperjs/core
npm install --save portal-vue@next
npm install bootstrap-vue

2. src/assets/styles下新建一个scss文件，用于自定义全局样式，写入以下内容：

// Theme color default definitions
$primary: #377dff !default;  /* 覆盖主题色预设值 */
$secondary: #6c757d !default;
$success: #00c9a7 !default;
$info: #A5ABD7 !default;
$warning: #f5ca99 !default;
$danger: #ed4c78 !default;
$light: #f8f9fa !default;
$dark: #343a40 !default;
$custom_color: #009A61 !default;  /* 新增主题变量 */

// This table defines the theme colors (variant names)
$theme-colors: () !default;
$theme-colors: map-merge(
  (
    'primary': $primary,
    'secondary': $secondary,
    'success': $success,
    'info': $info,
    'warning': $warning,
    'danger': $danger,
    'light': $light,
    'dark': $dark,
    'custom_color': $custom_color  /* 全部与上方定义保持一致 */
  ),
  $theme-colors
);

// Then import Bootstrap and BootstrapVue SCSS files (order is important)
@import 'node_modules/bootstrap/scss/bootstrap.scss';
@import 'node_modules/bootstrap-vue/src/index.scss';

3. 在main.js中引入该scss文件：

import Vue from 'vue'
import { BootstrapVue, BootstrapVueIcons } from 'bootstrap-vue'

import 'bootstrap/dist/css/bootstrap.css'
import 'bootstrap-vue/dist/bootstrap-vue.css'
import './assets/styles/custom.scss'

Vue.use(BootstrapVue)
Vue.use(BootstrapVueIcons)

4. 在组件中应用变量：

<b-button variant="primary">Buttonb-button>
<b-button variant="custom_color">Buttonb-button>

附录：Bootstrap Variables主题变量预设值

// Variables
//
// Variables should follow the `$component-state-property-size` formula for
// consistent naming. Ex: $nav-link-disabled-color and $modal-content-box-shadow-xs.
