vue-cli 3.x
1.安装
npm install -g @vue/cli
# OR
yarn global add @vue/cli
2.环境(windows)
E:\stydy>node -v
v8.12.0
E:\stydy>webpack -v
4.29.6
E:\stydy>npm -v
6.4.1
E:\stydy>vue -V
3.7.0
3.创建项目
我在此处想使用ant-design-vue
,所以创建了一个antd
的项目:
vue create antd
4.项目配置
我选择的项目配置如下:
Vue CLI v3.7.0
? Please pick a preset: Manually select features
? Check the features needed for your project: Babel, Router, Vuex, CSS Pre-processors
? Use history mode for router? (Requires proper server setup for index fallback in production) Yes
? Pick a CSS pre-processor (PostCSS, Autoprefixer and CSS Modules are supported by default): Less
? Where do you prefer placing config for Babel, PostCSS, ESLint, etc.? In dedicated config files
? Save this as a preset for future projects? No
? Pick the package manager to use when installing dependencies: NPM
5.运行
依赖安装完成后,cd到该项目路径下,运行:
$ cd antd
$ npm run serve
DONE Compiled successfully in 4229ms
App running at:
- Local: http://localhost:8080/
- Network: http://192.168.100.111:8080/
Note that the development build is not optimized.
To create a production build, run npm run build.
此时浏览器会访问 http://localhost:8080/ ,看到 Welcome to Your Vue.js App 的界面就算成功了。

使用ant-design-vue
由于在实际开发工程中,加载全部样式/组件会影响前端性能,因此我们直接采取按需加载组件及样式。
1.安装
npm install ant-design-vue --save-dev
npm install less less-loader --save-dev
2.引入src/main.js
// 以 Button 组件为例
import { Button } from 'ant-design-vue'
Vue.component(Button.name, Button);
3.组件使用
<template>
<div id="app">
<a-button type="danger">Danger</a-button>
</div>
</template>
4.babel-plugin-import
4.1安装
npm install babel-plugin-import --save-dev
4.2修改babel.config.js
module.exports = {
presets: [
'@vue/app',
],
// 配置babel-plugin-import, 用于按需加载组件代码和样式
plugins: [
[
"import",
{ libraryName: "ant-design-vue", libraryDirectory: "es", style: true }
]
],
}
4.3报错解决方案
此时重启项目,会遇到报错情况。以下两种方案任选其一即可
。两种方案:
-
配置
vue.config.js
在根目录下新建vue.config.js
:
module.exports = {
// 配置less
css: {
loaderOptions: {
less: {
javascriptEnabled: true,
}
}
},
}
- 修改
babel.config.js
// ...
plugins: [
[
"import",
{ libraryName: "ant-design-vue", libraryDirectory: "es", style: 'css' }
]
]
4.4完成
保存,重启项目:
npm run serve
可以看到,antd 组件的 js 和 css代码都会按需加载。
