我刚试过这个用git安装插件后： - https://github.com/donaldp24/CanvasCameraPlugin。，这段代码正常，我的问题可以通过error of installation of the plugin来解释。所以，我问是否有人可以帮助我安装插件，因为这里有以下步骤： - https://github.com/donaldp24/CanvasCameraPlugin
对我不起作用 我不明白为什么这不是我第一次尝试安装插件。

如果手动方式不适合你，可以试试＆＃34;在线Phonegap构建服务＆＃34;。它对我有用，它对你也有帮助。它会将你的插件绑定到你的应用程序中并为你构建它。试试这个解决方案，4步骤程序：

创建项目的Zip文件。（构建包 - ＆gt; Zip）
使用新插件更新config.xml文件
使用Phonegap构建服务构建应用程序
获取.apk，.ipa，.xap即本机应用程序
