webpack+vue2.0遇到的一些坑

Posted 2020-09-22

部分依赖包的版本：

 1 "dependencies": {
 2    "vue": "^2.3.3",
 3    "vue-router": "^2.3.1"
 4  },
 5 "devDependencies": {
 6 　 "eslint-loader": "^1.7.1",
 7 　 "stylus": "^0.54.5",
 8    "stylus-loader": "^3.0.1",
 9 　　"url-loader": "^0.5.8",
10    "vue-loader": "^12.1.0",
11    "vue-style-loader": "^3.0.1",
12    "vue-template-compiler": "^2.3.3",
13 　　"webpack": "^2.6.1",
14 }

1.使用stylus需要先再package.json中配置‘stylus‘和‘stylus-loader‘,并执行‘npm install stylus-loader stylus --save-dev‘命令。

1.1将所有styl文件依赖到一个主文件index.stly，然后在main.js里依赖主文件

//index.styl文件，通过@import将其他styl文件注入依赖
@import "base"
@import "mixin"
@import "icon"

 

2.在webpack.base.conf文件中配置别名以及扩展名

注意：‘__dirname’是两个下划线！

resolve: {
    extensions: [‘.js‘, ‘.vue‘, ‘.json‘, ‘.styl‘],
    alias: {
      ‘vue$‘: ‘vue/dist/vue.esm.js‘,
      ‘@‘: resolve(‘src‘),
      ‘src‘: path.resolve(__dirname, ‘../src‘),
      ‘common‘: path.resolve(__dirname, ‘../src/common‘),
      ‘components‘: path.resolve(__dirname, ‘../src/components‘)
    }
  }

配置好别名和扩展名后，main.js就可以这样写：

import Vue from ‘vue‘;
import App from ‘./App‘;
import Router from ‘vue-router‘;
//components前面可以加上‘@/‘，也可以省略不写
//如果没有别名，就要写成“import goods from ‘../components/goods/goods‘;“
import goods from ‘components/goods/goods‘;
import seller from ‘components/seller/seller‘;
import ratings from ‘components/ratings/ratings‘;
import ‘@/common/stylus/index‘;
