Maybe it's case by your package-archives setting. use mine setting and have a try.

(setq package-archives '(( "gnu"    . "http://mirrors.tuna.tsinghua.edu.cn/elpa/gnu/"   )
                         ( "org-cn" . "http://mirrors.tuna.tsinghua.edu.cn/elpa/org/"   )
                         ( "melpa"  . "http://mirrors.tuna.tsinghua.edu.cn/elpa/melpa/" )))
