问题描述
在使用 VSCode 在开发环境中运行我的应用程序时突然出现的错误，
main.js:7740 ERROR 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.

Angular 扩展可能无法正常工作，因为 ngcc 操作失败。尝试通过运行“npm/yarn run ngcc”来手动调用 ngcc。有关详细信息，请参阅扩展输出。

请帮忙
解决方法
对我来说是由 Angular Language Service 扩展引起的。
- 在扩展设置中启用旧版视图引擎
- 删除 node_modules 文件夹 (
npx rimraf node_modules) - 运行
npm install
编辑：应该在 this commit 中修复。
