借助 babel-plugin-component,我们可以只引入需要的组件,以达到减小项目体积的目的。
首先,安装 babel-plugin-component:npm install babel-plugin-component -D
然后,将 .babelrc (或者 babel.config.js)修改为:
module.exports = {
presets: [
'@vue/cli-plugin-babel/preset',
// ["es2015", { "modules": false }]
["@babel/preset-env", { "modules": false }]
],
"plugins": [
[
"component",
{
"libraryName": "element-ui",
"styleLibraryName": "theme-chalk"
}
]
]
}
在main.js所在目录创建一个plugins文件夹,该文件夹下创建一个element.js文件
// 按需引入
import Vue from 'vue'
// 需要注意的是,样式文件需要单独引入
import 'element-ui/lib/theme-chalk/index.css';
// 修改样式,根据实际项目自定义 (这里修改的样式会在整个项目所有界面的应用,全局的)
import '@/assets/css/DatePicker.css';
import '@/assets/css/Pagination.css';
import '@/assets/css/Table.css';
import '@/assets/css/select.css';

在MacOS下,less-loader安装的同时会自动安装less, 而windows和Linux环境则不会。
所以,使用less时,为了兼容性考虑,还是老老实实按照官网的要求:
npm install --save less less-loader
解决方案:命令行执行如下,然后重新安装less
npm cache clean --force
npm config set strict-ssl false
解决方案:
npm i @babel/preset-env -D
module.exports = {

'@vue/cli-plugin-babel/preset',
