我的 webpack 配置有什么问题吗？我在网上到处都按照教程说相同的配置方式。但我想我一定错过了什么。
webpack.common.js
const path = require('path');
const CleanWebpackPlugin = require('clean-webpack-plugin');
// const HtmlWebpackPlugin = require('html-webpack-plugin');
function resolve (dir) {
return path.join(__dirname, '..', dir)
}
module.exports = {
entry: {
library: './src/library.js',
HelloComp: './src/components/HelloComponent/HelloComponent.vue',
Bye: './src/components/ByeComponent/ByeComponent.vue',
MiniC: './src/components/MiniC/MiniC.vue',
TestAb: './src/components/test-ab/test-ab.vue'
},
plugins: [
new CleanWebpackPlugin(['dist'])
// Do not really need it as no live app is here
// new HtmlWebpackPlugin({
// title: 'Production'
// })
],
output: {
filename: '[name].js',
path: path.resolve(__dirname, 'dist'),

libraryTarget: 'umd'
},
