Vue 3.0 + Element Plus 踩坑

Posted 2021-12-05 lee576

运行 vue create xxxx 使用Vue Cli 4.5 创建 Vue 3.0 项目

1.项目打包以后，查看打包后的/dist/index.html，页面显示不出来，引用路径出现错误

 在项目根目录创建 vue.config.js 文件，配置如下

module.exports = {
    publicPath:'./'
}

2.运行 vue add element-plus 安装 Element Plus，出现如下错误

Can't resolve './fonts/element-icons.ttf' element-plus\\lib\\theme-chalk

在项目根目录创建 webpack.config.js 文件，配置如下

{
    test: /\\.(eot|svg|ttf|woff|woff2)(\\?\\S*)?$/,
    loader: 'file-loader'
}

如出现以下画面（红圈中的按钮），表示Element Plus安装成功

4. 使用el-icon与官方代码的不同，下图为官方代码

<template>
  <el-row>
    <el-button>Default</el-button>
    <el-button type="primary">Primary</el-button>
    <el-button type="success">Success</el-button>
    <el-button type="info">Info</el-button>
    <el-button type="warning">Warning</el-button>
    <el-button type="danger">Danger</el-button>
    <el-button>中文</el-button>
  </el-row>

  <el-row>
    <el-button plain>Plain</el-button>
    <el-button type="primary" plain>Primary</el-button>
    <el-button type="success" plain>Success</el-button>
    <el-button type="info" plain>Info</el-button>
    <el-button type="warning" plain>Warning</el-button>
    <el-button type="danger" plain>Danger</el-button>
  </el-row>

  <el-row>
    <el-button round>Round</el-button>
    <el-button type="primary" round>Primary</el-button>
    <el-button type="success" round>Success</el-button>
    <el-button type="info" round>Info</el-button>
    <el-button type="warning" round>Warning</el-button>
    <el-button type="danger" round>Danger</el-button>
  </el-row>

  <el-row>
    <el-button :icon="Search" circle></el-button>
    <el-button type="primary" :icon="Edit" circle></el-button>
    <el-button type="success" :icon="Check" circle></el-button>
    <el-button type="info" :icon="Message" circle></el-button>
    <el-button type="warning" :icon="Star" circle></el-button>
    <el-button type="danger" :icon="Delete" circle></el-button>
  </el-row>
</template>
<script lang="ts">
import { Search, Edit, Check, Message, Star, Delete } from '@element-plus/icons'
export default {
  data() {
    return {
      Search,
      Edit,
      Check,
      Message,
      Star,
      Delete,
    }
  },
}
</script>

 首先官方示例使用TypeScript写的，其次去掉 “lang="ts” 代码虽然运行不报任何错误，但按钮上的图标确是不出现的，我想这个应该是只适用于TypeScript的写法，下面是我用JS写的，图标可以正常显示

<template>
  <el-row>
    <el-button>Default</el-button>
    <el-button type="primary">Primary</el-button>
    <el-button type="success">Success</el-button>
    <el-button type="info">Info</el-button>
    <el-button type="warning">Warning</el-button>
    <el-button type="danger">Danger</el-button>
    <el-button>中文</el-button>
  </el-row>

  <el-row>
    <el-button plain>Plain</el-button>
    <el-button type="primary" plain>Primary</el-button>
    <el-button type="success" plain>Success</el-button>
    <el-button type="info" plain>Info</el-button>
    <el-button type="warning" plain>Warning</el-button>
    <el-button type="danger" plain>Danger</el-button>
  </el-row>

  <el-row>
    <el-button round>Round</el-button>
    <el-button type="primary" round>Primary</el-button>
    <el-button type="success" round>Success</el-button>
    <el-button type="info" round>Info</el-button>
    <el-button type="warning" round>Warning</el-button>
    <el-button type="danger" round>Danger</el-button>
  </el-row>

  <el-row>
    <el-button :icon="Search" circle><el-icon><Search/></el-icon></el-button>
    <el-button type="primary" circle><el-icon><Edit/></el-icon></el-button>
    <el-button type="success" circle><el-icon><Check/></el-icon></el-button>
    <el-button type="info" circle><el-icon><Message/></el-icon></el-button>
    <el-button type="warning" circle><el-icon><Star/></el-icon></el-button>
    <el-button type="danger" circle><el-icon><Delete/></el-icon></el-button>
  </el-row>
</template>
<script>
import { Search, Edit, Check, Message, Star, Delete } from '@element-plus/icons'
export default {
  components: {
      Search,
      Edit,
      Check,
      Message,
      Star,
      Delete
  }
}
</script>

效果如下
