装饰器不支持“Ng2DropdownMenu”函数调用模板编译过程中的错误，而是调用了“触发器”

Question

使用npm重新安装package.json文件后。我在运行命令ng build -prod时遇到了错误

装饰器不支持“Ng2DropdownMenu”函数调用模板编译过程中的Ng2DropdownMenu错误，而是调用了“触发器”。

现在，据我所知，Ng2DropdownMenu不在我的项目中使用，也无法在文件或行no中找到错误。

我该怎么做才能修好它..？

首先，在您的fullTemplateTypeCheck文件中创建“tsconfig.json”：false并重新构建，然后它可能会说明实际的错误。
