javascript - 未捕获（承诺）：错误：Angular JIT 编译失败：'@angular/compiler' 未加载！在角度 9

问题描述

我用 angular 9 创建了一个 webaite，但是 angular 有问题。

在某些路线我有错误：

ERROR Error: Uncaught (in promise): Error: Angular JIT compilation failed: '@angular/compiler' not loaded!
  - JIT compilation is discouraged for production use-cases! Consider AOT mode instead.
  - Did you bootstrap using '@angular/platform-browser-dynamic' or '@angular/platform-server'?
  - Alternatively provide the compiler with 'import "@angular/compiler";' before bootstrapping.

  - Did you bootstrap using '@angular/platform-browser-dynamic' or '@angular/platform-server'?
  - Alternatively provide the compiler with 'import "@angular/compiler";' before bootstrapping.

但在某些路线中，我没有这个错误。另一个奇怪的事情是，在本地它工作正常，但在服务器上它不起作用。有什么问题，我该如何解决？

在我的服务器中，我将文件放在文件app夹中，而在本地机器中我没有这个文件夹。

这里是angular.json：

解决方案

如果你像我一样从谷歌来到这里。当我在 app.module.ts 中包含一个 Angular 材质组件而不是它的模块时，我的错误出现了

特别注意：每当您向 app.module.ts 添加新的材质模块时，您必须停止（并重新启动）ng serve，否则您将收到此错误。

改变这个

imports: [
   BrowserModule,
   HttpClientModule,
   AppRoutingModule,
   BrowserAnimationsModule,
   MatDialog, // <====== this is the error
],

对此

imports: [
   BrowserModule,
   HttpClientModule,
   AppRoutingModule,
   BrowserAnimationsModule,
   MatDialogModule, // <====== this is the solution
],
