我使用了 onesignal_flutter https://pub.dev/packages/onesignal_flutter

在我的颤振项目中

并按照此步骤在此链接中为 ios 设置 onsignal sdk

https://documentation.onesignal.com/docs/flutter-sdk-setup

我在 Visual Studio 代码终端中运行这两个命令

flutter clean和flutter build ios

我收到这个错误

这是我的 Podfile 代码

请有任何帮助

我有一个类似的问题，我还没有 100% 理解，但我相信文档不容易理解，而且有点过时。我把所有的东西都做了两次并且不会工作，同样的错误......我必须添加这一行，没有那个，因为另一个错误。

use_frameworks!

尝试这样的事情：

# 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', {
  '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
