在我的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时，会显示：

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，但我不是这样做的;我所包含的唯一的cordova脚本是<script type="text/javascript" src="cordova.js"></script>。
有谁知道发生了什么以及如何解决错误？
