标签： angular syncfusion

我已经创建了一个应用，并想使用ng build --prod来构建它。这样做时，我收到了当前版本的syncfusion的错误消息。

以下是我遇到的错误：

ERROR in ./node_modules/@syncfusion/ej2-angular-dropdowns/@syncfusion/ej2-angular-dropdowns.es5.js
Module build failed (from ./node_modules/@angular-devkit/build-optimizer/src/build-optimizer/webpack-loader.js):
