错误TS2305:模块“/node_node/rxjs/Rx”没有导出成员‘可订阅’

Question

我有一个用角5构建的项目。这是package.json

  }
}

我已经下载了npm和angular。

​

在安装这些模块之后，我进行了npm安装以获得所需的模块。但是当我做“服务”时，它会显示出一个错误。

node_modules/@angular/flex-layout/core/typings/observable-media/observa ble-media.d.ts中的错误(1，22)：错误TS2305:模块‘“D:/Projects/FlexFunding/app/Clie nt/node_modules/rxjs/Rx“没有导出的成员'Subscribable‘。

​

我知道现在它是角6，并且rxjs已经在这个版本中更新了。但是，我如何解决这个问题，而不把这个项目从角版本5迁移到6，我只需要构建和运行这个项目。

我尝试过从运行项目的节点模块下替换rxjs文件夹。但没有运气。

编辑:我已经卸载当前版本，并降级到版本角cli版本1.7.4，但错误是相同的。

Answer 1

ERROR in node_modules/@angular/flex-layout/core/typings/observable-media/observa ble-media.d.ts(1,22)：error TS2305:模块‘D:/Projects/FlexFunding/app-dk/Clie nt/node_node/rxjs/Rx“”没有导出成员'Subscribable’。

在package.json中，依赖项之一是

"@angular/flex-layout": "^5.0.0-beta.14"

对于^ of "^5.0.0-beta.14"，npm安装flex-layout的最新版本，felx-layout在最新版本中使用RxJS 6。但是，由于该项目是一个Angular 5项目，所以它使用了早期版本的RxJs。因此，flex布局无法导入所需的库，因为RxJs 6不在那里。

所以，对我起作用的解决方案是改变package.json

"@angular/flex-layout": "5.0.0-beta.14"

然后是npm install

Answer 2

尝试重新安装您的应用程序

npm i

如果这不起作用，请尝试删除node_modules文件夹并重新安装。
