因此，我尝试在我的（正在运行的）Ionic应用程序中安装一个新插件，该插件应为https://ionicframework.com/docs/native/firebase-dynamic-links/
我遇到了一个奇怪的错误，所以我尝试了一些尝试，最终回到了使用git reset来完全撤消所做操作的位置。
...但是错误不会消失。
我试图升级Cordova和Ionic，再次删除node_modules和npm install，然后删除并重新添加Android平台...没有任何帮助。

我真的需要帮助来了解到底发生了什么以及如何克服它。
答案 0 :(得分：0)
好的，终于让它工作了。删除了plugins文件夹，在我的插件列表中删除了不必要的东西，删除了node_modules文件夹，删除了Android平台，升级了所有内容，重新安装了所有内容（如果需要，您可以将ionic cordova prepare用于插件，或者如果您删除了Android平台，则将其重新添加将可以获取插件）。构建。
