我最近尝试安装第三方插件：https://github.com/bradleygore/nativescript-materialdropdownlist并按照自述文件使用它。在我运行我的应用程序并遇到错误之前，似乎没有任何异常。我很快注意到它试图在错误的文件夹中找到插件。

该模块肯定在我的node_modules文件夹中，但{N}正在尝试从/ app / nativescript-materialdropdownlist而不是/ app / tns_modules / nativescript-materialdropdownlist加载它，它实际上位于build的输出中。
我尝试删除平台文件夹并重建。我已经尝试删除node_modules并重新安装所有内容。我不知道还能做什么。
