javascript - react native 重复错误 : Duplicated files or mocks

Question

更新 xCode 后，我一周后面临以下错误。我无法在设备上运行应用程序。我不认为问题出在 xcode 上，因为即使我尝试在 android 设备上运行，也会出现同样的问题。

当我们使用重置选项运行 npm start 时会出现问题，同样的错误也会发生。

唯一的选择是在删除 ios 构建文件夹后在 android 设备上运行。

我已经删除了多次节点模块，也进行了全新安装，但每次都会出现问题。

我的原因是我有两个不同的package.json name 具有相同值的文件属性(property)。
