對Core Data模型進行微小更改後發現鏈接器錯誤

Question

我開始了一個新項目，在我通過CocoaPods添加MagicalRecord之後（我的第一次使用CocoaPods的經驗）開始建立了新項目。

在構建我的數據模型之後，我收到一個錯誤，告訴我我沒有在兩個實體之間包含預期的反比關係。我走進了數據模型和修正這個，現在我是在重建收到此錯誤：

Ld /Users/myName/Library/Developer/Xcode/DerivedData/ProjectName-ewvswzrvrwxktphioghlirgkuyju/Build/Products/Debug-iphonesimulator/ProjectName.app/ProjectName normal x86_64 
    cd "/Users/myName/Desktop/Everything from DT 1:20:15/App projects/WMMG/ProjectName" 
    export IPHONEOS_DEPLOYMENT_TARGET=8.1 
    export PATH="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin:/Applications/Xcode.app/Contents/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin" 
    /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang -arch x86_64 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator8.1.sdk -L/Users/myName/Library/Developer/Xcode/DerivedData/ProjectName-ewvswzrvrwxktphioghlirgkuyju/Build/Products/Debug-iphonesimulator -F/Users/myName/Library/Developer/Xcode/DerivedData/ProjectName-ewvswzrvrwxktphioghlirgkuyju/Build/Products/Debug-iphonesimulator -filelist /Users/myName/Library/Developer/Xcode/DerivedData/ProjectName-ewvswzrvrwxktphioghlirgkuyju/Build/Intermediates/ProjectName.build/Debug-iphonesimulator/ProjectName.build/Objects-normal/x86_64/ProjectName.LinkFileList -Xlinker -rpath -Xlinker @executable_path/Frameworks -Xlinker -objc_abi_version -Xlinker 2 -ObjC -lPods-MagicalRecord -framework CoreData -fobjc-arc -fobjc-link-runtime -Xlinker -no_implicit_dylibs -mios-simulator-version-min=8.1 -lPods -Xlinker -dependency_info -Xlinker /Users/myName/Library/Developer/Xcode/DerivedData/ProjectName-ewvswzrvrwxktphioghlirgkuyju/Build/Intermediates/ProjectName.build/Debug-iphonesimulator/ProjectName.build/Objects-normal/x86_64/ProjectName_dependency_info.dat -o /Users/myName/Library/Developer/Xcode/DerivedData/ProjectName-ewvswzrvrwxktphioghlirgkuyju/Build/Products/Debug-iphonesimulator/ProjectName.app/ProjectName 

ld: library not found for -lPods-MagicalRecord 
clang: error: linker command failed with exit code 1 (use -v to see invocation) 

的錯誤似乎明確地指向與鏈接器和豆莢的一個問題。問題是我沒有經驗調試鏈接器問題，並且當我發現類似問題的引用開始討論「依賴性」等時，我感覺非常深刻。很顯然，MagicalRecord庫沒有找到，但我不知道我所做的更改可能會導致這個問題，我更不知道如何糾正它。

有人可以幫忙嗎？

核心數據會觸發這一點非常奇怪。要解決鏈接問題，請嘗試輸入pod install（先到包含您的項目工作區的文件夾）。
