module.exports = config


2.babel 升级 6.x 到 7.x


(1) @babel/core




Module build failed (from ./node_modules/babel-loader/lib/index.js):
Error: Cannot find module '@babel/core'
 babel-loader@8 requires Babel 7.x (the package '@babel/core'). 
 If you'd like to use Babel 6.x ('babel-core'), you should install 'babel-loader@7'.


没找到 @babel/core ，这里把 babel-core 卸载，并安装 @babel/core 。




npm un babel-core
npm i -D @babel/core


(2) @babel/preset-*




Module build failed (from ./node_modules/babel-loader/lib/index.js):
Error: Plugin/Preset files are not allowed to export objects, only functions.




将 babel-preset-* 卸载，重新安装 @babel/preset-* ，并且修改 .babelrc 中的 presets




npm:
- babel-preset-env
+ @babel/perset-env

.babelrc:
- "presets": ["env"]
+ "presets": ["@babel/preset-env"]



另，stage-*已弃用


(3) @babel/plugin-*




Module build failed (from ./node_modules/babel-loader/lib/index.js):
TypeError: this.setDynamic is not a function
  at PluginPass.pre
  ...



这次是插件了，一样把babel-plugin-*卸载，重新安装@babel/plugin-*


然后修改.babelrc文件


具体的包名可以在 npm仓库 里找


(4) 最终文件




.babelrc
{
  "presets": ["@babel/preset-env"],
  "plugins": [
      "@babel/plugin-transform-runtime"
  ]
}

package.json
"devDependencies": {
  "@babel/core": "^7.1.2",
  "@babel/plugin-transform-runtime": "^7.1.0",
  "@babel/preset-env": "^7.1.0",
  "babel-loader": "^8.0.4"，
  
  ...
 },
"dependencies": {
  "@babel/runtime": "^7.1.2",
  "vue": "^2.5.17",
  "vue-loader": "^15.4.2",
  "vue-router": "^3.0.1",
  "vuex": "^3.0.1",
  "webpack": "^4.22.0",
  "webpack-cli": "^3.1.2",
  "webpack-dev-server": "^3.1.10",
  "webpack-merge": "^4.1.4"
  ...
 }




(5) 总结


babel 舍弃了以前的 babel-*-* 的命名方式，改成了 @babel/*-*


修改依赖和 .babelrc 文件后就能正常启动项目了。
3.vue-loader 15.x vueLoaderPlugin




vue-loader was used without the corresponding plugin. 
Make sure to include VueLoaderPlugin in your webpack config.




//两个方式都可以的，随便用一个

const VueLoaderPlugin = require('vue-loader/lib/plugin');

// 或者 

const { VueLoaderPlugin } = require('vue-loader');


plugins: [
  // make sure to include the plugin for the magic
  new VueLoaderPlugin()
]
