AngularMaterialDemo / node_modules / rxjs / Rx“'没有导出的成员'Subscribable'

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

package.json：

{
  "name": "angular-material-demo",
  "version": "0.0.0",
  "license": "MIT",
  "scripts": {
    "ng": "ng",

    "karma-coverage-istanbul-reporter": "^1.2.1",
    "karma-jasmine": "~1.1.0",
    "karma-jasmine-html-reporter": "^0.2.2",
    "protractor": "~5.1.2",
    "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？？

Answer 1

您的问题是由npm的旧版本引起的。要检查您的版本，请使用：

npm -v

使用apt install安装了非常老的npm版本（3.5.2）。升级到最新版本：

sudo npm install -g npm

再次检查您的版本，您可能需要打开一个终端以刷新它。截至2018年7月4日，最新npm为6.1.0。清除node_modules文件夹，然后重新下载模块：

rm -rf ./node_modules
npm install

Answer 2

尝试将您的版本升级到

"typescript": "2.7.2" 
"@angular/cdk": "^5.2.4"
"@angular/material": "^5.2.4"

issue

Answer 3

我遇到了同样的问题，这是由于package.json中的flex-layout版本所致。 使用命令`

首先卸载模块@ angular / flex-layout

  

npm卸载@ angular / flex-layout

然后安装flex-layout@2.0.0-beta.10-4905443

使用命令

的版本

  

npm install @ angular / flex-layout @ 2.0.0-beta.10-4905443-保存

这解决了我的问题。
