Javascript Phonegap cordova_plugins.js抛出错误500

在my Phonegap项目中，浏览器控制台中显示以下错误：

GET http://192.168.137.1:3000/cordova_plugins.js 500 (Internal Server Error)
  exports.injectScript @ cordova.js:1528
  injectIfNecessary @ cordova.js:1536
  exports.load @ cordova.js:1616
  (anonymous) @ cordova.js:1129

当我转到

http://192.168.137.1:3000/cordova_plugins.js

，它显示：

出现

cordova_plugins.js

错误的一般原因似乎是将其包含在应用程序的html中，但我没有这样做；我包含的唯一cordova脚本是

有人知道发生了什么以及如何解决错误吗？

我没有指定Cordova的哪个版本，所以我认为它是最新的
