xcode 10 error: multiple commands produce - react native
提问by Michael Hsu
So there are a lot of questions like this already, but I'm having the same error, notrelating to cocoapods or info.plist, at least I don't think, because none of the solutions worked for me.
因此，有很多这样的问题了，但我有同样的错误，不涉及的CocoaPods或info.plist中，至少我不认为，因为没有解决方案对我来说有效。
I just recently upgraded to Xcode 10.0, and building my react native app gives this error:
我最近刚刚升级到 Xcode 10.0，在构建我的 React Native 应用程序时出现以下错误：
Multiple commands produce '/Users/username/Library/Developer/Xcode/DerivedData/appname-code/Build/Products/Release-iphoneos/appname.app':
1) Target 'appname' has create directory command with output '/Users/username/Library/Developer/Xcode/DerivedData/appname-code/Build/Products/Release-iphoneos/appname.app'
2) That command depends on command in Target 'appname': script phase “[CP] Copy Pods Resources”
How do I fix this error?
我该如何解决这个错误？

- 将 cocoapods 升级到最新版本 - 运行“sudo gem install cocoapods”

The issue was produced by some libRN...afiles. I fixed it by removing some of them like libRNScreens.a and libRNGestureHandler.a from Build Phases -> Link Binary with Librariessince they were already being referenced from another libraries. Others had to be replaced by their Pod version like libRNDeviceInfo.a:
这个问题是由一些libRN...a文件产生的。我通过从Build Phases -> Link Binary with Libraries 中删除其中一些像 libRNScreens.a 和 libRNGestureHandler.a 来修复它，因为它们已经被其他库引用了。其他人必须被他们的 Pod 版本替换，比如 libRNDeviceInfo.a：
