当为离子文件安装npm时出现错误（npm ERR！-rc.0“：{” name“：” @ angular / common“，” version“：” 4.0.0-rc.0“，” peerDependen ）

Question

我是离子框架的新手。 安装完所有必需的软件后，我移至该文件并使用终端安装了npm。但是我遇到了一个错误，这可能是什么原因？ （以前，node和npm已安装在我的电脑中； 节点版本：v8.4.0， npm版本：5.3.0）

这是我的package.json

      "cordova-plugin-ionic-keyboard": {}
    },
   "platforms": [

    ]
 }
}

我得到的错误是

 $ npm install
 npm ERR! Unexpected end of input at 1:15785
 npm ERR! -rc.0":{"name":"@angular/common","version":"4.0.0-rc.0","peerDependen
 npm ERR!   

请帮助解决此问题。
