在npm安裝期間無法解析package.json數據

Question

在Windows 10上進行npm安裝期間，出現此錯誤，我正在使用節點v6.10.3和npm v3.10.10

請幫助糾正此問題。

我得到的錯誤

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文件內容：

{  
   "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",
      "typings":"typings",
      "postinstall":"typings install"
   },
   "license":"ISC",
   "dependencies":{  
      "angular2":"2.0.0-beta.14",

      "reflect-metadata":"0.1.2",
      "rxjs":"5.0.0-beta.2",
      "zone.js":"0.6.6"
   },
   "devDependencies":{

   }
}

您可能在行中有一個不可見的字符\\r ：

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

該字符破壞了package.json文件的json解析。 嘗試用手重寫文本的該部分，或使用正則表達式搜索在文本編輯器中將其刪除。
