无法在角度应用程序中安装Flex模块

Question

我正在使用 AngularMaterial 和 FlexLayout 在 Angular 中实现示例应用程序。

我已经成功安装并实现了Angular Material Components。我还使用以下命令安装了Flex

npm install @angular/flex-layout --save

但是当我运行我的应用程序时，我在Eclipse Terminal中收到以下警告消息，如下所示

而且我的控制台中也出现以下错误。

下面显示的是package.json文件

    "ts-node": "~3.2.0",
    "tslint": "~5.7.0",
    "typescript": "~2.4.2"
  }
}

我也尝试执行以下步骤。

Edited package.json: Had to change my version for @angular/compiler-cli. In my case I had to bring it back to 5.2.0, as it somehow got to 5.2.10.

Deleted the node_modules directory.

Ran: npm install

Installed: npm install @angular/flex-layout.

但是我又遇到了不同的错误。我还尝试将package.json文件中的flex版本从"@angular/flex-layout": "^6.0.0-beta.16"更改为"@angular/flex-layout": "^2.0.0-beta.12"，但是仍然出现这些错误。

有人可以帮我解决这个问题吗？
