小编给大家分享一下babel7.x和webpack4.x如何配置vue项目，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！
1.webpack 4.x 插件 extract-text-webpack-plugin
(node:2628) DeprecationWarning: Tapable.plugin is deprecated. Use new API on `.hooks` instead i ｢wds｣: Project is running at http://localhost:8300/ i ｢wds｣: webpack output is served from / i ｢wds｣: Content not from webpack is served from F:\private\plugin-insert\dist F:\private\plugin-insert\node_modules\webpack\lib\Chunk.js:838 throw new Error( ^ Error: Chunk.entrypoints: Use Chunks.groupsIterable and filter by instanceof Entrypoint instead at Chunk.get (F:\private\plugin-insert\node_modules\webpack\lib\Chunk.js:838:9) at F:\private\plugin-insert\node_modules\extract-text-webpack-plugin\dist\index.js:176:48 at Array.forEach () at F:\private\plugin-insert\node_modules\extract-text-webpack-plugin\dist\index.js:171:18 at AsyncSeriesHook.eval [as callAsync] (eval at create (F:\private\plugin-insert\node_modules\tapable\lib\HookCodeFactory.js:32:10), :7:1) at AsyncSeriesHook.lazyCompileHook (F:\private\plugin-insert\node_modules\tapable\lib\Hook.js:154:20) at Compilation.seal (F:\private\plugin-insert\node_modules\webpack\lib\Compilation.js:1231:27) at hooks.make.callAsync.err (F:\private\plugin-insert\node_modules\webpack\lib\Compiler.js:541:17) at _done (eval at create (F:\private\plugin-insert\node_modules\tapable\lib\HookCodeFactory.js:32:10), :9:1) at _err1 (eval at create (F:\private\plugin-insert\node_modules\tapable\lib\HookCodeFactory.js:32:10), :32:22)
extract-text-webpack-plugin 提取单独打包css文件时报错，官方安装部分的文档只写到了webpack 3，目前还没有webpack 4版本，可以使用 extract-text-webpack-plugin@next 解决，也可以使用 mini-css-extract-plugin 。
mini-css-extract-plugin 插件用法如下：
const MiniCssExtractPlugin = require("mini-css-extract-plugin") ;
const config = module.exports = {
plugins: [
new MiniCssExtractPlugin({
filename: "[name].[chunkhash:8].css",
chunkFilename: "[id].css"
})
],
module: {
rules: [
{
test: /\.css$/,
use: [
MiniCssExtractPlugin.loader,
"css-loader"
]
}
]
}
}
module.exports = config2.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()
