xcode Apple Mach-O-Linker 错误 CocoaPods

Apple Mach-O-Linker Error CocoaPods

提问by KFDoom

I've been trying to get my app up and running. From what I could tell the app was missing Cocoapods as a dependency. So. I installed and added Cocoapods. But I'm still getting the same error for whatever reason. I'm an inexperienced developer trying to teach himself I must add.

我一直在尝试启动并运行我的应用程序。据我所知，该应用程序缺少 Cocoapods 作为依赖项。所以。我安装并添加了 Cocoapods。但无论出于何种原因，我仍然遇到相同的错误。我是一个没有经验的开发人员，试图自学，我必须补充。

This error usually occurs either when you don't have the correct frameworks (might be missing one) or when you don't have the right thing in linker flags.

当您没有正确的框架（可能缺少一个）或链接器标志中没有正确的内容时，通常会发生此错误。

Go to the main page for the app (on the navigation thing on the left click on your apps name or the top section) -> Build Settings and under Linker Flags, make sure there is nothing in your Other Linker Flags. I had this same error when I had -ObjC in my other Linker Flags.

转到应用程序的主页（在左侧的导航部分，单击您的应用程序名称或顶部部分）-> 构建设置，然后在链接器标志下，确保您的其他链接器标志中没有任何内容。当我在其他链接器标志中有 -ObjC 时，我也遇到了同样的错误。

You might also want to try adding -lPods to your Other Linker Flags or adding the CoreGraphics framework if you don't already have it.

如果您还没有，您可能还想尝试将 -lPods 添加到您的其他链接器标志或添加 CoreGraphics 框架。

Good luck

祝你好运

Open workspace file, not project file. Cocoapods automatically creates a xcworkspace file on the same directory as xcproject file.

打开工作区文件，而不是项目文件。Cocoapods 会自动在与 xcproject 文件相同的目录中创建一个 xcworkspace 文件。

Xcode started displaying this message and I tried pretty much everything to solve it. What finally did the trick for me was deleting all content from ~/Library/Developer/Xcode/DerivedData/

Xcode 开始显示此消息，我尝试了几乎所有方法来解决它。最终对我有用的是删除所有内容~/Library/Developer/Xcode/DerivedData/
