根据提示文件 vendors.js ，https://juejin.cn/post/7046782284107612174#%E9%A1%B9%E7%9B%AE%E5%88%86%E6%9E%90

减小体积方法；
1.taro官方通过编译减少体积的方法都试了一遍，并没有什么用（生气😠）
https://docs.taro.zone/docs/guide#%E6%89%93%E5%8C%85%E4%BD%93%E7%A7%AF

其他尝试：
1.优化编译速度
https://docs.taro.zone/en/docs/compile-optimized/

2.可视化webpack文件大小插件

npm install webpack-bundle-analyzer --save-dev
//webpack中配置
const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;
 
module.exports = {
  plugins: [
    new BundleAnalyzerPlugin()
  ]
}

dist: "webpack -p"
