您可以在podfile中尝试此部分。

• 替换以下代码：

post_install do |installer|
      installer.pods_project.targets.each do |target|
        flutter_additional_ios_build_settings(target)
      end
    end

• 替换为以下代码：

post_install do |installer|
  installer.pods_project.targets.each do |target|
      flutter_additional_ios_build_settings(target)
      target.build_configurations.each do |config|
        xcconfig_path = config.base_configuration_reference.real_path
        xcconfig = File.read(xcconfig_path)
        xcconfig_mod = xcconfig.gsub(/DT_TOOLCHAIN_DIR/, "TOOLCHAIN_DIR")
        File.open(xcconfig_path, "w") { |file| file << xcconfig_mod }
      end
  end
end

我希望这个解决方案可以为您工作。
