warning '[source] The version should be included in the Git tag.'

修改version号和tag号一致后，通过命令pod lib lint检查是ok的，但执行pod trunk push *.podspec之后，会直接提示： [!] The podspec does not validate. 随后又执行了pod trunk lint *.podspec后，提示 [!] The spec did not pass validation, due to 1 error. 好陶醉的提示，尝试升级了cocoapods到1.0.0.beta.2版本后，终于有了详细的提示： warning: Could not find remote branch 1.0.2 to clone. fatal: Remote branch 1.0.2 not found in upstream origin 额，原来tag只是被我打在本地了，push到origin就ok了.在通过lint验证就都ok了。

unable to find a license file

将podspec文件中的 s.license = "MIT"修改为s.license = { :type => 'MIT', :file => 'LICENSE' }
