beego orm linux运行问题

出现一个异常提醒,

 cannot find Asia/shanghai in zip file /usr/local/go/lib/time/zoneinfo.zip

must have one register DataBase alias named `default`

其实是大小写问题

$ unzip -l -f /usr/local/go/lib/time/zoneinfo.zip | grep -i shanghai
      172  07-06-2016 08:15   Asia/Shanghai

root:pwd@tcp(10.9.46.22:3306)/ads_db?charset=utf8&loc=Asia%2Fshanghai
[ORM]2017/02/06 16:36:53 register db Ping `default`, cannot find Asia/shanghai in zip file /usr/local/go/lib/time/zoneinfo.zip
must have one register DataBase alias named `default`

后面发现时 Shanghai大小写问题.但是mac没有这种问题.linux有这个问题
