CocoaPods could not find compatible versions for pod “JCore“

问题描述

Flutter的项目中引入了极光的两个插件jpush_flutter和jverify使用的核心模块JCore版本不一致，导致合并Podfile出现问题：

AdministratordeMacBook-Air:ios administrator$ pod install
/Users/administrator/VSCodeProjects/kiss_you_new/ios/Podfile:41: warning: ... at EOL, should be parenthesized?
Analyzing dependencies
[!] CocoaPods could not find compatible versions for pod "JCore":
  In Podfile:
    jpush_flutter (from `.symlinks/plugins/jpush_flutter/ios`) was resolved to 0.0.2, which depends on
      JCore (= 2.7.1)

    jverify (from `.symlinks/plugins/jverify/ios`) was resolved to 0.0.1, which depends on
      JCore (= 2.6.2)

    jverify (from `.symlinks/plugins/jverify/ios`) was resolved to 0.0.1, which depends on
      JVerification (= 2.7.5) was resolved to 2.7.5, which depends on
        JCore (< 6.0.0, >= 2.1.6)

解决

将jpush_flutter的JCore模块降级版本：

点开ios目录下.symlinks/plugins，打开jpush_flutter/ios/jpush_flutter.podspec文件，修改如下两行：

  s.version          = '0.0.1'

  s.dependency 'JCore','2.6.2'

总结

由于jverify插件的JCore版本版本和jpush_flutter的JCore版本不一致，后续可以适当降低jpush_flutter和jverify版本，待我后续有空，将匹配的版本列出来，这样就不需要修改podspec文件了。
