大部分配置跟着教程走就行，个别配置需要微调

webpack.conifg.js中这一块配置无需修改

{
        test: /\.(scss|less|css)$/,
        use: ['style-loader', 'css-loader', 'sass-loader']
}

整体配置如下

      async: false
    }),
    // 将TypeScript类型检查错误以弹框提示
    // 如果fork-ts-checker-webpack-plugin的async为false时可以不用

      skipSuccessful: true,
    }),
