Question

美好的一天！我写了load_rules以便能够读取将在Prolog程序中使用的文件。但是，尽管Prolog最初是由我创建的，但Prolog似乎并没有读取我的文件。

我的代码：

load_rules :-
  write('file name? '),
  read(F),
  load_rules(F).

load_rules(F) :-
 % clear_db,
  see(F),
  lod_ruls,
  write('rules loaded'), nl,
  seen, !.

lod_ruls :-repeat,
           read_word_list(L), size(L,X),write(X),nl,
           formal_english(L,[]), write('rule:    '), printlist(L), nl,
           translate(L,X),
           L=[end].

查询：

?- load_rules.
file name? joggers_facts_and_rules.

ERROR: source_sink `joggers_facts_and_rules' does not exist (No such file or directory)

我什至尝试创建.txt和.pl文件，只是为了确保无济于事：/

在此方面，我将不胜感激，非常感谢！

尽管文件已存在但仍未读取Prolog文件
