不支持指定多个post_install钩子的无效Podfile文件

Question

我使用cocoapods 1.1.1，在我的podfile中我有多个post_install钩子。我得到了这个错误:

[!] Invalid `Podfile` file: [!] Specifying multiple `post_install` hooks is unsupported..
-------------------------------------------
 #
 >  post_install do |installer|
 #      installer.pods_project.targets.each do |target|

以前有人遇到过同样的问题吗?是的!我有一个post_install在我的1个目标和另一个在全局范围内。我可以搬进去，但为什么呢?

Answer 1

解决方案2022

当我从我的主要目标中删除我的代码并移动到全局作用域的post_install块时，它的工作就像魅力一样。

由于某些原因，如果您添加了多个post_install(例如全局和一个目标)，将它们移动到同一个全局块中，并添加if-else语句来管理目标。

暂时解决了这个冲突。把代码放到Podfile中。

def multiple_post_install(flutter_application_path)
  #read podhelper from flutter_application_path
  flutter_podhelper = File.read(File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb'))
  #find the post_install end location by hardcoding
  post_install_string = 'post_install do |installer|'
  location = flutter_podhelper.index(post_install_string)
  location += post_install_string.length
  #declare your own hook func
  update_configs_func = %q[
  update_configs(installer)]
  #insert the func you declare
  flutter_podhelper.insert(location, update_configs_func)
  return flutter_podhelper
end
flutter_application_path = 'path/to/my_flutter/'
flutter_podhelper = multiple_post_install(flutter_application_path)
eval(flutter_podhelper, binding)
def update_configs(installer)
  #put your own custom code
end

def main_pods
pod 'CocoaLumberjack', '2.0.0'
pod 'MBProgressHUD', '0.9.1'
post_install do |installer_representation|
    installer_representation.pods_project.targets.each do |target|
        if target.name == 'Pods-AFNetworking'
            target.build_configurations.each do |config|
                config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)']
                config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] << '_AFNETWORKING_ALLOW_INVALID_SSL_CERTIFICATES_=1'
            end
        end
    end
end

我有类似的问题，这是因为我在POD文件中添加的位置权限。然后我注释掉这部分，它就工作了。

# post_install do |installer|
#   installer.pods_project.targets.each do |target|
#     flutter_additional_ios_build_settings(target)
#   end
# end
post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |config|
      config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
        '$(inherited)',
        ## Add this line
         'PERMISSION_LOCATION=1'
      ]
    end
  end
end

像这样把它们全部移到一个地方，对我来说很有效。

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
  end
end
post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
     if config.build_settings['WRAPPER_EXTENSION'] == 'bundle'
     config.build_settings['DEVELOPMENT_TEAM'] = 'S09DP9UN6F'
   end
  end
 end
end

后

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
  end
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      if config.build_settings['WRAPPER_EXTENSION'] == 'bundle'
        config.build_settings['DEVELOPMENT_TEAM'] = 'S09DP9UN6F'
      end
    end
  end
end
