尝试将颤振添加到iOS应用程序时，命令PhaseScriptExecution失败，退出代码为非零

我正在尝试添加颤振到现有的应用程序。所以在制作应用程序之前，我尝试了全新的Xcode 10单视图应用程序。我遵循了这里的教程，在我的目标的构建阶段添加了运行脚本后陷入了困境。它给出了一个错误：

错误：

我试过下面的东西

我的pod文件：

# Uncomment the next line to define a global platform for your project
platform :ios, '10.0'

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

  # Pods for AFEiOS

  target 'AFEiOSTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'AFEiOSUITests' do
    inherit! :search_paths
    # Pods for testing
  end

    flutter_application_path = '/Users/dhavalkansara/FlutterToNative/AFE_flutter/'
    eval(File.read(File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')), binding)


end

• 已经在我的项目中添加了flatter\u ROOT

请帮我解决这个问题。

这对我很有效：
1） 将此添加到您的播客文件：

flutter_application_path = '/Users/dhavalkansara/FlutterToNative/AFE_flutter/'
    eval(File.read(File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')), binding)

    install_all_flutter_pods(flutter_application_path)

另外，对于每个目标，您可能也需要这样做，即

target 'AFEiOSTests' do
    inherit! :search_paths
    install_all_flutter_pods(flutter_application_path)
    # Pods for testing
  end

  target 'AFEiOSUITests' do
    inherit! :search_paths
    install_all_flutter_pods(flutter_application_path)
    # Pods for testing
  end

---

2） 运行

pod安装
这对我来说很有用：xcode 11.3.1

xcode->targets->runner

在构建阶段：运行脚本和精简二进制文件，选择：仅在安装时运行脚本谢谢Alexander Lozano，我上传了Xcode 12.0.1版的图像

天哪，我已经花了两天的时间试图解决这个问题，非常感谢。这么做有什么坏处吗？是的，你仍然会使用flift.。\除了开玩笑，我一直在寻找答案，但似乎没有人知道。与此同时，这对我来说不起作用，我的探索还在继续(
