CocoaPods找不到兼容版本的 pod "AFNetworking"。

Question

我想更新我的AFNetworking到版本。pod 'AFNetworking', '~> 4.0' 。但我得到以下错误。

[!] CocoaPods could not find compatible versions for pod "AFNetworking":
  In Podfile:
    AFNetworking (~> 4.0)

    AFOAuth2Manager was resolved to 2.0.0, which depends on
      AFNetworking (~> 2.2)

CocoaPods could not find compatible versions for pod "AFNetworking/NSURLConnection":
  In Podfile:
    AFOAuth2Manager was resolved to 2.2.0, which depends on
      AFNetworking/NSURLConnection (~> 2.2)

None of your spec sources contain a spec satisfying the dependency: `AFNetworking/NSURLConnection (~> 2.2)`.

我使用pod版本1.8.4和macOS 10.15.3与xcode11.3.1.请你帮助我如何解决这个问题。

Answer 1

有一个类似的问题，改变为

pod 'AFNetworking', '~> 4.0.1'

并删除一个过时的依赖关系

# pod 'AFNetworking+RetryPolicy', '~>1.0.3'

足以解决这个问题

在AFNetworking贡献者的帮助下，我已经解决了这个问题。

我更新了我的podfile，如下所示。

pod 'AFNetworking', :source => 'https://github.com/ElfSundae/CocoaPods-Specs.git'
pod 'AFOAuth2Manager','~> 3.0'
