角度5到6，没有向后兼容的RxJS (rxjs-compat)

Question

我参与了将一个项目从Angular 5.2.11迁移到6.0.0的相当艰巨的任务，并且我在使用RxJS 6(这是Angular >6所要求的)时遇到了一些困难。例如，我得到了这个和其他许多类似的东西：

ERROR in node_modules/angularfire2/auth/auth.d.ts(3,10): error TS2305: Module '"/Users/jadam/brightwater2/node_modules/rxjs/Observable"' has no exported member 'Observable'.

安装rxjs-compat显然可以解决这个问题，但我想知道是否可以在没有rxjs-compat的情况下解决此类错误。

这个topic提出了同样的问题，但从来没有得到满意的答案。

我已经将import { Observable } from 'rxjs/Observable'改为'import { Observable } from 'rxjs'，但无济于事。(顺便说一句，这两种方式都不起作用，就像有人在链接的帖子和其他帖子中建议的那样。)

删除您的节点模块文件夹并重新运行NPM INSTALL > npm install并使用import { Observable } from 'rxjs';
