지난 주에 정상적으로 작동했습니다. 나는Erlang 셸에서 내 모듈로드가 중지되었습니다.
cd myprojectdir erl (erlang shell). c(room). {ok, R} = room:go().
가 나는 내 방 모듈과 상호 작용, R에게 메시지를 보낼 gen_server 사용할 수있는 열 것입니다.
나는 카우보이 라우팅 지점에서 시작했습니다. 일이 잘 작동하는 것을보고 있었는데, 오늘 그것을 보았을 때 컴파일 오류가 발생했습니다. 그래서 나는 내 주점으로 되돌아 갔다. 쉘에서 여전히 오류가 발생하고 심지어 커밋 몇 개를 롤백합니다.
room : go()를 호출하려고하면 다른 모듈은 undef으로 인쇄됩니다. 교대로 각각 컴파일하면 room()이 작동합니다.
방은 테이블을 걷어차 고, 테이블은 시계, 좌석 및 게임을 시작하고 게임은 보드 및 액션에서 시작합니다.
