[英]Error in building Angular 10 app with AWS Amplify
I get a console error, when I want to run my angular app with AWS amplify.当我想使用 AWS amplify 运行我的 angular 应用程序时,出现控制台错误。 Building the app with
ng start
works, I only get a warning about using commonJS.使用
ng start
构建应用程序,我只收到关于使用 commonJS 的警告。
WARNING in...\node_modules\@aws-amplify\ui-components\dist\esm\loader.mjs depends on '@aws-amplify/core'. CommonJS or AMD dependencies can cause optimization bailouts.
But when I want to load the app in my browser, I get the following console error and the app wont start.但是当我想在浏览器中加载应用程序时,我收到以下控制台错误并且应用程序无法启动。
I used the official guide from AWS Integrating Amazon Cognito With Web and Mobile Apps .我使用了 AWS Integrating Amazon Cognito With Web and Mobile Apps的官方指南。
Here is my package.json file.这是我的 package.json 文件。
