Named enum cannot correct generate

[lijianxin1202]

I have a schema like this:

"OspKvUserAuthType": {
    "enum": [
        "UserAuthTypeNone = \"none\""
    ],
    "type": "string",
    "example": "none",
    "title": "UserAuthType"
},

generate result is:

export enum OspKvUserAuthType {
  UserAuthTypeNoneNone = "UserAuthTypeNone = "none"" 
 }
