Swift编译器错误：缺少必需的模块；

Question

我想创建依赖于其他容器的自定义容器。我有podspec文件

 ...
 s.source_files = "ios/**/*.{h,c,m,swift}"
 s.requires_arc = true

 s.dependency "UserSDK" 

UserSDK是要在自定义模块中使用的Pod。它具有自己的依赖性，例如FirebaseCore，FirebaseMessaging UserSDK podspec

在我的CustomModule.swift文件中具有

import Foundation
import UserSDK

要使用自定义库，请通过pod文件添加它；

# Uncomment the next line to define a global platform for your project
# platform :ios, '11.0'

target 'MyTarget' do

pod 'FBLazyVector', :path => "../modules/react-native/Libraries/FBLazyVector"
pod 'FBReactNativeSpec', :path => "../modules/react-native/Libraries/FBReactNativeSpec"
pod 'RCTRequired', :path => "../modules/react-native/Libraries/RCTRequired"
pod 'RCTTypeSafety', :path => "../modules/react-native/Libraries/TypeSafety"
pod 'React', :path => '../modules/react-native/'
pod 'React-Core', :path => '../modules/react-native/'
pod 'React-CoreModules', :path => '../modules/react-native/React/CoreModules'
pod 'React-Core/DevSupport', :path => '../modules/react-native/'
pod 'React-RCTActionSheet', :path => '../modules/react-native/Libraries/ActionSheetIOS'
pod 'React-RCTAnimation', :path => '../modules/react-native/Libraries/NativeAnimation'
pod 'React-RCTBlob', :path => '../modules/react-native/Libraries/Blob'
pod 'React-RCTImage', :path => '../modules/react-native/Libraries/Image'
pod 'React-RCTLinking', :path => '../modules/react-native/Libraries/LinkingIOS'
pod 'React-RCTNetwork', :path => '../modules/react-native/Libraries/Network'
pod 'React-RCTSettings', :path => '../modules/react-native/Libraries/Settings'
pod 'React-RCTText', :path => '../modules/react-native/Libraries/Text'
pod 'React-RCTVibration', :path => '../modules/react-native/Libraries/Vibration'
pod 'React-Core/RCTWebSocket', :path => '../modules/react-native/'

pod 'CustomModule', :path => "../CustomModule"

end

错误

如果我将use_frameworks!添加到podfile中的目标上，它可以工作，但是其他依赖项不起作用

Answer 1

在podspec文件中，缺少几个字段，我猜是

• Deployment_Target

• Source Files

  在inherit! :search_paths之前在Podfile中使用end。

，对于您的特定错误，请在podfile

中添加以下内容

pod 'Firebase/Core'
pod 'Firebase/Messaging'

或参考： Xcode error: Missing required module 'Firebase'
