在Beta 0.3.2上使用Firebase-auth插件的Flutter的Xcode构建错误：不兼容的块指针

概述这涉及firebase-auth插件的颤振. 我在两台mac计算机上运行相同的代码. 我刚刚对后者进行了全新安装,并在FirebaseAuthPlugin.m上出现了构建错误：不兼容的块指针 /Users/sergebesnard/Development/flutter/.pub-cache/hosted/pub.dartlang.org/firebase_auth-0.5.9/ios/Clas 这涉及firebase-auth插件的颤振.

我刚刚对后者进行了全新安装,并在FirebaseAuthPlugin.m上出现了构建错误：不兼容的块指针

/Users/sergebesnard/Development/Flutter/.pub-cache/hosted/pub.dartlang.org/firebase_auth-0.5.9/ios/Classes/FirebaseAuthPlugin.m:69:53:Incompatible block pointer types sending 'voID (^)(FIRUser *__strong,NSError *__strong)' to parameter of type 'FIRAuthDataResultCallback _Nullable' (aka 'voID (^)(FIRAuthDataResult * _Nullable __strong,NSError * _Nullable __strong)')

在我的笔记本电脑上,代码构建顺利,唯一的区别是beta版本,即0.3.1并且安装了androID工具链.

在iMac上(失败)：

Podfile是一样的：

# Uncomment this line to define a global platform for your project# platform :ios,'9.0'# CocoaPods analytics sends network stats synchronously affecting Flutter build latency.ENV['COCOAPODS_disABLE_STATS'] = 'true'def parse_KV_file(file,separator='=')  file_abs_path = file.expand_path(file)  if !file.exists? file_abs_path    return [];  end  pods_ary = []  skip_line_start_symbols = ["#","/"]  file.foreach(file_abs_path) { |line|      next if skip_line_start_symbols.any? { |symbol| line =~ /^\s*#{symbol}/ }      plugin = line.split(pattern=separator)      if plugin.length == 2        podname = plugin[0].strip()        path = plugin[1].strip()        podpath = file.expand_path("#{path}",file_abs_path)        pods_ary.push({:name => podname,:path => podpath});      else        puts "InvalID plugin specification: #{line}"      end  }  return pods_aryendtarget 'Runner' do  use_frameworks!  # Prepare symlinks folder. We use symlinks to avoID having Podfile.lock  # referring to absolute paths on developers' machines.  system('rm -rf Pods/.symlinks')  system('mkdir -p Pods/.symlinks/plugins')  # Flutter Pods  generated_xcode_build_settings = parse_KV_file('./Flutter/Generated.xcconfig')  if generated_xcode_build_settings.empty?    puts "Generated.xcconfig must exist. If you're running pod install manually,make sure Flutter packages get is executed first."  end  generated_xcode_build_settings.map { |p|    if p[:name] == 'FlutteR_FRAMEWORK_DIR'      symlink = file.join('Pods','.symlinks','Flutter')      file.symlink(file.dirname(p[:path]),symlink)      pod 'Flutter',:path => file.join(symlink,file.basename(p[:path]))    end  }  # Plugin Pods  plugin_pods = parse_KV_file('../.Flutter-plugins')  plugin_pods.map { |p|    symlink = file.join('Pods','plugins',p[:name])    file.symlink(p[:path],symlink)    pod p[:name],'ios')  }endpost_install do |installer|  installer.pods_project.targets.each do |target|    target.build_configurations.each do |config|      config.build_settings['ENABLE_BITCODE'] = 'NO'    end  endend

在这两种情况下,pod版本都是1.5.0.

坦率地说,我宁愿不在我的工作设置上测试升级颤振sdk,我仍然需要处理那些东西……

我不知道这是否有用,但在安装过程中,我遇到了在XCODE上安装颤动的问题,因为当时XCODE没有完全设置.
颤动的医生确实要求我安装包六,并因为python @ 2版本中的冲突而出现问题,所以我强制通过brew python @ 2卸载并重新安装它,然后可以通过`pip install six`安装

如果这是原因,我将不得不重新安装XCODE&扑.希望不是这样的.

谢谢

解决方法 更新cocoapods的存储库.

pod repo update

然后删除Podfile,Podfile.lock,Pos目录,.Flutter-plugins,.packages,pubspec.lock
