我将我的 Angular 应用程序从版本 8 迁移到了 9。运行 ng serve --open 后,我的应用程序在浏览器中打开并卡在加载屏幕上,并在控制台窗口中显示此错误:
core.js:610 Uncaught 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.

最佳答案
checkin app.module.ts 如果您缺少模块...例如,有时在模块文件中人们会导入 HttpClient 而不是 HttpClient模块或者可能是因为有棱 Angular 的 Material ,例如人们使用 MatButton 而不是 MatButtonModule 有时会导致这个问题。
