Visual studio 2015 错误平台android已经添加。在Visual Studio 2015上使用爱奥尼亚2制作塔可

我下载了TACO，创建了一个新的Ionic 2 RC项目， 没有改变什么,， 单击播放F5

然后出现此错误：

Error       Platform android already added.

请确保您所在的目录中没有已包含ionic应用程序的目录，这可能会发生。

有时遇到类似问题，请执行ionic平台删除-android，然后重新添加，这会很有帮助。您还可以删除.tmp文件夹和node_modules文件夹，然后再次运行npm安装。可能有助于解决您的问题。祝你好运托尼，运气好吗？你找到解决方案了吗？我不再尝试了，我不知道问题是否仍然存在。
