“正在运行 pod install...” 无限

Question

我想在 IOS Simulator 上运行我的应用程序 flutter App，但它无限显示“正在运行 pod install...”

我试图找到解决方案，但找不到任何解决方案。

这是我的可可豆荚自动生成的豆荚文件：

# 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 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

target 'Runner' do
  # Prepare symlinks folder. We use symlinks to avoid having Podfile.lock
  # referring to absolute paths on developers' machines.
  system('rm -rf .symlinks')
  system('mkdir -p .symlinks/plugins')

  # Flutter Pods
  generated_xcode_build_settings = parse_KV_file('./Flutter/Generated.xcconfig')
  if generated_xcode_build_settings.empty?
    puts "Generated.xcconfig must exist. If you're running pod install manually, make sure flutter packages get is executed first."
  end
  generated_xcode_build_settings.map { |p|
    if p[:name] == 'FLUTTER_FRAMEWORK_DIR'
      symlink = File.join('.symlinks', 'flutter')
      File.symlink(File.dirname(p[:path]), symlink)
      pod 'Flutter', :path => File.join(symlink, File.basename(p[:path]))
    end
  }

  # Plugin Pods
  plugin_pods = parse_KV_file('../.flutter-plugins')
  plugin_pods.map { |p|
    symlink = File.join('.symlinks', 'plugins', p[:name])
    File.symlink(p[:path], symlink)
    pod p[:name], :path => File.join(symlink, 'ios')
  }
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['ENABLE_BITCODE'] = 'NO'
    end
  end
end

预期的结果是“应用程序应该很快在 IOS 模拟器上运行”但它卡在“正在运行 pod install...”然后给出以下错误：自动分配ios具有8.0目标版本的平台，Runner因为没有指定平台。请在您的 Podfile 中为此目标指定平台。见https://guides.cocoapods.org/syntax/podfile.html#platform。

Answer 1

podfile.lock之后从 iOS 文件夹中删除文件，然后转到 ios 文件夹并运行以下命令

Pod install

它将安装 podfile 中的所有软件包。

此外，您需要设置目标平台。留在iOS文件夹中并运行以下命令

open Runner.xcworkspace

那么您的应用程序将在 XCode 中打开。单击“Runner”并将您的目标平台设置为 8.0。我用这个修复了我的 iOS 构建问题，希望这对你有用。

Answer 2

使用终端。转到你的 ios 文件夹运行 pod install --verbose 你会看到发生了什么
