Question

我有一个角度为4的应用程序，在ng server的本地计算机上正常运行但是当我尝试使用ng build -- prod构建生产应用程序时，我遇到错误，没有出错生产运行。错误是： -

WARNING in Invalid background value at 12864:14. Ignoring.

完整详细错误

ERROR in : Type ModalsComponent in E:/Projects/Rudram Admin/Code/app/src/app/pages/ui-features/modals/modals.component.ts is part of the declarations 
of 2 modules: JobListModdule in E:/Projects/Rudram Admin/Code/app/src/app/pages/joblist/joblist.module.ts and UiFeaturesModule in E:/Projects
/Rudram Admin/Code/app/src/app/pages/ui-features/ui-features.module.ts! Please consider moving ModalsComponent in E:/Projects/Rudram Admin/Code
/app/src/app/pages/ui-features/modals/modals.component.ts to a higher module that imports JobListModdule in E:/Projects/Rudram Admin/Code/app/src
/app/pages/joblist/joblist.module.ts and UiFeaturesModule in E:/Projects/Rudram Admin/Code/app/src/app/pages/ui-features/ui-features.module.ts. You 
can also create a new NgModule that exports and includes ModalsComponent in E:/Projects/Rudram Admin/Code/app/src/app/pages/ui-features/modals
/modals.component.ts then import that NgModule in JobListModdule in E:/Projects/Rudram Admin/Code/app/src/app/pages/joblist/joblist.module.ts and
 UiFeaturesModule in E:/Projects/Rudram Admin/Code/app/src/app/pages/ui-features/ui-features.module.ts.

注意 - ＆gt; 如果我只是简单地使用ng biuld，那么它不会产生任何错误，但在这种情况下，应用程序会加载大量时间加载大约5到6分钟。

因为错误说ModalsComponent（modals.component.ts）在两个模块modals.component.ts is part of the declarations of 2 modules: JobListModdule ... and UiFeaturesModule中声明。

因此，如错误所示，创建共享模块并在那里导入ModalsComponent会更好 You can also create a new NgModule that exports and includes ModalsComponent in E:/Projects/Rudram Admin/Code/app/src/app/pages/ui-features/modals /modals.component.ts then import that NgModule in JobListModdule in E:/Projects/Rudram Admin/Code/app/src/app/pages/joblist/joblist.module.ts and UiFeaturesModule in E:/Projects/Rudram Admin/Code/app/src/app/pages/ui-features/ui-features.module.ts.直接来自文档https://angular.io/guide/sharing-ngmodules
