打包的时候出现Error: No module factory available for dependency type: CssDependency
网上其他的做法是修改的vue.config.js.我这个是分出来的webpack 有点不太会。请前辈们帮忙看看
webpack.base.config.js文件
const path = require('path'); // node.js 中的基本包，用于处理路径
const VueLoaderPlugin = require('vue-loader/lib/plugin');
const MiniCssExtractPlugin = require('mini-css-extract-plugin')
const CopyPlugin = require('copy-webpack-plugin')
const { CleanWebpackPlugin } = require("clean-webpack-plugin");
const devMode = process.env.NODE_ENV !== 'production';
module.exports = {
entry: {
main: './src/main',
vendors: './src/vendors'
},
output: {
path: path.join(__dirname, '../dist/assets'), // 输出文件所在目录
},
module: {

]
}
},
exclude: /node_modules/
},
{
test: /.less$/, // less 处理
use: [
MiniCssExtractPlugin.loader, // 这样相当于抽离成一个css文件， 如果希望抽离成分别不同的css, 需要再引入MiniCssExtractPlugin，再配置
'css-loader', // css-loader 用来解析@import这种语法
'less-loader',
'postcss-loader'
],
},
