错误 TS1005：';'预期的。 TypeScript Angular 6 For First Build error rxjs inside node_modules

Question

新手上路，请多包涵

我正在构建我的第一个 Angular 应用程序。我正在使用这个命令 ng new purchase-section 创建一个新的 Angular 应用程序。但是当我使用 ng serve -o 执行应用程序时，出现以下错误。

node_modules/rxjs/internal/types.d.ts(81,44) 中的错误：错误 TS1005：’;‘预期的。 node_modules/rxjs/internal/types.d.ts(81,74): 错误 TS1005: ‘;‘预期的。 node_modules/rxjs/internal/types.d.ts(81,77)：错误 TS1109：预期表达式。

我已经检查 types.d.ts 因为我知道它是由 Angular 创建的。我无法理解错误。请注意，在我收到此错误后，我删除了 node_modules 并使用 npm install 希望我能逃脱但仍然收到此错误。

这是我的 package.JSON 文件：
