在npm安装期间无法解析package.json数据

Question

在Windows 10上进行npm安装期间，出现此错误，我正在使用节点v6.10.3和npm v3.10.10

请帮助纠正此问题。

我得到的错误

npm ERR! npm  v3.10.10
npm ERR! file C:\angular2-helloworld\package.json
npm ERR! code EJSONPARSE

npm ERR! Failed to parse json
npm ERR! Unexpected token '\r' at 5:71

package.json文件内容：

{  
   "name":"angular2-helloworld",
   "version":"1.0.0",
   "scripts":{  
      "start":"tsc && concurrently \"npm run tsc:w\" \"npm run lite\" ",
      "tsc":"tsc",
      "tsc:w":"tsc -w",
      "lite":"lite-server",

      "postinstall":"typings install"
   },
   "license":"ISC",
   "dependencies":{

   },
   "devDependencies":{

   }
}

您可能在行中有一个不可见的字符\\r ：

"start":"tsc && concurrently \"npm run tsc:w\" \"npm run lite\" ",

该字符破坏了package.json文件的json解析。 尝试用手重写文本的该部分，或使用正则表达式搜索在文本编辑器中将其删除。
