Question

当我尝试在 ios 模拟器上运行我的 react native 应用程序时，我收到了这个错误。

我尝试清理构建文件夹，再次运行 pod install 但没有任何效果。我被困在这个错误上。我无法找到导致此错误的原因。另外，我检查了 myApp > Libraries 文件夹，没有任何内容(空文件夹)。

将 react-native-unimodules 库添加到我正在开发的应用程序后，我遇到了完全相同的错误。
经过几个小时尝试不同的解决方案，我们能够通过将 react-native-unimodules 库从当前的 0.14.7 版本降级到 0.13.3 来修复错误。

更改了 package.json

中的 react-native-unimodules 版本

重新安装包(yarn install for me)

cd ios，然后 pod deintegrate(只是为了确定)，然后 pod install

在 XCode 中转到 Product 选项卡并从那里清理构建文件夹

启动应用，编译成功

希望它可以帮助遇到该问题的其他人。
