:dets.open_file参数错误

Question

iex(1)> :dets.open_file(:storage, [{:type, :set}])           
{:ok, :storage}

当我尝试使用其他参数时，这对于Erlang文档来说应该是完全合适的：

iex(2)> :dets.open_file(:storage, [{:type, :set}, {:file, "file"}])
** (ArgumentError) argument error

更新：

iex(4)> :dets.open_file(:storage, [{:type, :set}, {:file, 'file'}])
{:error, :incompatible_arguments}

Answer 1

尝尝这个

:dets.open_file('file', [{:type, :set}])

Answer 2

:dets.open_file(:storage, [{:type, :set}, {:file, String.to_atom("file")}])
