Ocaml：语法错误

Question

我试图弄清楚为什么这不起作用，我得到错误：语法错误。我错过了一个“;”某处？

let way_tags_to_hashtbl way =
  let hashtbl = Hashtbl.create 1 in
  let rec way_tags_to_hashtbl_partial list = match list with
    | a::list' -> Hashtbl.add hashtbl (a.k, a.v); way_tags_to_hashtbl_partial list'
    | a::[] -> Hashtbl.add hashtbl (a.k, a.v)
    | [] -> [];
  way_tags_to_hashtbl_partial way.wtag; hashtbl
;; <------ ERROR HERE

谢谢。

我认为您缺少大约两行的in：

let way_tags_to_hashtbl way =
  let hashtbl = Hashtbl.create 1 in
  let rec way_tags_to_hashtbl_partial list = match list with
    | a::list' -> Hashtbl.add hashtbl (a.k, a.v); way_tags_to_hashtbl_partial list'
    | a::[] -> Hashtbl.add hashtbl (a.k, a.v)
    | [] -> [] in (* !!! HERE !!! *)
  way_tags_to_hashtbl_partial way.wtag; hashtbl
;;

我这台机器上没有安装ocaml，无法检查...
