ng build --configuration=production --base-href /my-app/ --prod

通常这是我为生产构建 angular 8 应用程序的方式。但是在我当前的应用程序中，它在编译时给了我一个错误。

非法状态下的错误：引用没有变量的类型 {"filePath":"/node_modules/@angular/router/router.d.ts","name":"RouterLink","members":[]}

快速搜索建议将build-optimizer&aot标志设置为false. 构建过程在执行时成功：

ng build --configuration=production --base-href /my-app/ --prod --build-optimizer=false --aot=false

我有两个疑问：

  1. 问题是什么referring to a type without a variable error？我不介意共享我的代码，但由于我无法理解错误的相关性，因此无法理解应该共享代码的哪一部分。

  2. 设置aot为false可以吗？一个中型博客 建议

    AOT 的性能改进非常显着，不容忽视
