我正在添加audio_service软件包以在后台运行音频。在android中可以使用，但作者尚未在iOS中实现，因此在iOS中运行应用时出现错误。

运行pod安装时出错 在iPhone 8 Plus上启动应用程序时出错。
下面是pod文件：
# 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'
project 'Runner', {

'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
# Prepare symlinks folder. We use symlinks to avoid having Podfile.lock
# referring to absolute paths on developers' machines.
system('rm -rf .symlinks')
system('mkdir -p .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('.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
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['ENABLE_BITCODE'] = 'NO'
end
end
end
在这里，我还将pod文件更改为if p[:name] != 'audio_service'
# Plugin Pods
plugin_pods = parse_KV_file('../.flutter-plugins')
plugin_pods.map { |p|
if p[:name] != 'audio_service'
symlink = File.join('.symlinks', 'plugins', p[:name])
File.symlink(p[:path], symlink)
pod p[:name], :path => File.join(symlink, 'ios')
end
}
但是没有用。
如何解决此问题？我们可以在subspace.yaml文件中设置限制吗？像这样的依赖项只能安装在android平台上吗？无论如何，我只是想修复它。

只需删除您的ios/Podfile.lock文件，然后在同一目录中运行
pod install
您应该很好。这样可以确保您使用的版本正确。
