ios - 找不到“firebase_messaging/FirebaseMessagingPlugin.h”文件

Question

我正在尝试在 ios 上运行我的 flutter 应用程序，但我收到此错误

/ios/Runner/GeneratedPluginRegistrant.m:6:9: 'firebase_messaging/FirebaseMessagingPlugin.h' file not found

这是我的 podfile 内容

# 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.

  'Debug' => :debug,
  'Profile' => :release,
  'Release' => :release,
}

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_ary
end

target 'Runner' do
  use_frameworks!
  # Prepare symlinks folder. We use symlinks to avoid having Podfile.lock

  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 pub get is executed first."
  end
  generated_xcode_build_settings.map { |p|
    if p[:name] == 'FLUTTER_FRAMEWORK_DIR'
      symlink = File.join('.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('.symlinks', 'plugins', p[:name])
    File.symlink(p[:path], symlink)
    pod p[:name], :path => File.join(symlink, 'ios')
  }
end

# Prevent Cocoapods from embedding a second Flutter framework and causing an error with the new Xcode build system.

post_install do |installer|

      config.build_settings['ENABLE_BITCODE'] = 'NO'
      config.build_settings['SWIFT_VERSION'] = '4.1'
    end
  end
end

这是我运行pod install时的结果

我的 Xcode 版本是 10.0

我该如何修复它？提前致谢

Answer 1

当有疑问时，我只是删除并重新安装，而不是手动处理级联依赖项。

1) rm 你的 ios/Pods dir 和 Podfile.lock 文件(当然要备份)

2) rm 你的~/.pub-cache/hosted/pub.dartlang.org/

3) flutter 干净

4) flutter 包获取

5) pod 存储库更新

6) 像平常一样运行 flutter 可执行文件(调用 pod install)，或者手动运行 pod install。
