Flutter pod 文件问题

Question

我的 pod 文件似乎已损坏，并且我无法在 iPhone 上安装应用程序。 我收到错误的 pod 文件 “正在运行 pod 安装 退出（sigterm） 例外：运行 pod install 时出错”。我已经尝试过删除旧的 pod 文件、flutter clean、flutter get packages 并再次为 iOS 构建，但遇到了相同的错误。您可以在下面找到我的 pod 文件和 pubspec.yaml，但没有构建后 pubspec.yaml 中出现错误。有关如何修复此错误的任何建议吗？

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', {
  'Debug' => :debug,
  'Profile' => :release,
  'Release' => :release,
}

def flutter_root
  generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
  unless File.exist?(generated_xcode_build_settings_path)
    raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
  end

  File.foreach(generated_xcode_build_settings_path) do |line|
    matches = line.match(/FLUTTER_ROOT\=(.*)/)
    return matches[1].strip if matches
  end
  raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end

require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)

flutter_ios_podfile_setup

target 'Runner' do
  use_frameworks!
  use_modular_headers!

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end

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

# The following section is specific to Flutter.
flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.

  # To add assets to your application, add an assets section, like this:
  assets:
      - assets/images/
      - assets/icons/
  #   - images/a_dot_ham.jpeg

  # An image asset can refer to one or more resolution-specific "variants", see

  # For details regarding adding assets from package dependencies, see
  # https://flutter.dev/assets-and-images/#from-packages

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
fonts:
    - family: Oxygen
      fonts:
        - asset: fonts/Oxygen-Regular.ttf
        - asset: fonts/Oxygen-Bold.ttf
          weight: 700

Answer 2

就我而言，这两种解决方案都不起作用，我不知所措。然而，在尝试了一切之后，我终于找到了一个适合我的解决方案。

要解决该问题，请按照以下步骤操作：

1. 在 Flutter SDK 安装中找到 podhelper.rb 文件。这 文件应位于 路径/to/flutter-sdk/packages/flutter_tools/bin/podhelper.rb。
2. 在文本编辑器中打开 podhelper.rb 文件。
3. 寻找 return [] 行，除非 File.exists？文件路径。
4. 替换文件.存在？与 File.exist?，所以该行变为 return [] 除非文件.存在？文件路径。
5. 将更改保存到 podhelper.rb 文件。

也可以帮忙

rm -Rf ios/Podgfile.lock
pod install --repo-update
