I pip install gsutil on a Mac OS 10.10 laptop and receive this error. I was under the impression that enum was a python 3.4 feature. The pypi package may need updating to list this as a dependency? Activity Sign up for free to join this conversation on GitHub. Already have an account?
根据你的描述console is not defined控制台是没有定义的具体错误还要是要看具体错误信息上下文来参考。
If enumType is an enumeration that is defined by using the FlagsAttribute attribute, the method returns false if multiple bit fields in value are set but value does not correspond to a composite enumeration value, or if value is a string concatenation of the names of multiple bit flags. In...
IsDefined()如果为枚举定义了输入值,则静态方法将返回。否则$true,静态方法将返回$false。 使用此方法检查某个值是否对枚举有效,而无需处理无效的参数错误。 可以在 System.Enum 基类类型或特定枚举类型上使用静态方法。 Syntax 复制 [System.Enum]::IsDefined([<enum-name>], <value>) Syntax 复制 [<enum...

code is not good enough because IsDefined takes the value of the enum at runtime. So if later someone added a new value (say Ultraviolate = -1) to the enum IsDefined will start allowing the value -1 one through. This is true whether the enum is defined in the same assembly as the...
