在flutter中运行ios时找不到模块'cloud_firestore'

Question

我正在尝试通过 runnig flutter run 在 ios 上运行该应用程序，但我收到此错误，podfile 为空我尝试手动安装它但它不起作用这是 podfile

# Uncomment the next line to define a global platform for your project
platform :ios, '13.0'

target 'Runner' do
  # Comment the next line if you don't want to use dynamic frameworks
  use_frameworks!

  # Pods for Runner

end

这是控制台中的输出

Xcode's output:
↳
