	Short: "枚举生成器",
	Long:  `枚举生成器`,
	RunE: func(cmd *cobra.Command, args []string) error {

EnumCmd 枚举生成器

var InitCmd = &cobra.Command{
	Use:   "init",
	Short: "初始化",

	RunE: func(cmd *cobra.Command, args []string) error {

InitCmd 初始化系统

var RootCmd = &cobra.Command{
	Use:   "mcube",
	Short: "mcube 分布式服务构建工具",
	Long:  `mcube ...`,
	RunE: func(cmd *cobra.Command, args []string) error {
		return errors.New("no flags find")
	},
}

RootCmd represents the base command when called without any subcommands

Functions

func Execute

func Execute()

Execute adds all child commands to the root command sets flags appropriately. This is called by main.main(). It only needs to happen once to the rootCmd.
