angular8 - 动态导入在 Angular 8 库中不起作用

Question

构建使用动态导入的角度库时出错。

当库中包含一个文件时，使用动态导入导入一个LazyModule，

import('./lazy/lazy.module').then(({ LazyModule }) => {
      const MyComponent = LazyModule.entry;
    ....

构建将失败并抛出以下错误。

Error: You must set "output.dir" instead of "output.file" when generating multiple chunks.

请在 public-api.ts 中导出 lazy.module
