我正在处理一个意外的变化，导致 Angular 服务器在 npm start 时运行非常缓慢。在 npm start 中会出现 "Generating browser application bundles (phase: building)..." 的提示，并且花费了大量时间。

然后它会添加一些奇怪的警告。
node_modules\canvg\lib\index.es.js depends on '@babel/runtime-corejs3/regenerator'. CommonJS or AMD dependencies can cause optimization bailouts.
我按照 Angular 页面上的说明尝试了一下，链接为：https://angular.io/guide/build#configuring-commonjs-dependencies，但是没有帮助，我仍然看到这些消息。
npm start 和 ng serve 的运行时间超过1分钟。
