angular - RXJS 7 - TS2693：'AjaxDirection' 仅指一种类型，但在此处用作值

Question

我升级了我的 Angular 11 项目RxJS 7，在网络风暴中它建议我更改一些Subject导入，一旦我更新这些导入，我就会遇到错误

ERROR: node_modules/rxjs/dist/types/internal/ajax/types.d.ts:9:40 - error TS1110: Type expected.

9 export declare type AjaxResponseType = `${AjaxDirection}_${ProgressEventType}`;
                                         ~~~
node_modules/rxjs/dist/types/internal/ajax/types.d.ts:9:43 - error TS2693: 'AjaxDirection' only refers to a type, but is being used as a value here.

9 export declare type AjaxResponseType = `${AjaxDirection}_${ProgressEventType}`;
                                            ~~~~~~~~~~~~~

                                                             ~~~~~~~~~~~~~~~~~

An unhandled exception occurred: node_modules/rxjs/dist/types/internal/ajax/types.d.ts:9:40 - error TS1110: Type expected.

有人解决了这个试图迁移到的问题RxJs7吗？
