Postgresql 및 devise db 마이그레이션 실패

Question

devise gem을 사용할 때 postgresql을 사용하여 db를 마이그레이션하는 데 rake를 사용할 수 없습니다.

rake db:migrate --trace 
** Invoke db:migrate (first_time) 
** Invoke environment (first_time) 
** Execute environment 
** Invoke db:load_config (first_time) 
** Execute db:load_config 
** Execute db:migrate 
** Invoke db:_dump (first_time) 
** Execute db:_dump 
** Invoke db:schema:dump (first_time) 
** Invoke environment 
** Invoke db:load_config 
** Execute db:schema:dump 

rake db:migrate:status 아무것도 반환 :

database: sampleapp_development 

Status Migration ID Migration Name 
-------------------------------------------------- 

나는 rails g scaffold <WHATEVER> name email을하고 난 갈퀴 DB를 실행하면 모든 잘 작동하지만, 유증 ... 아무것도를 마이그레이션 할 수 있습니다.

고안에 의해 생성 된 마이그레이션 파일을 확인하시기 바랍니다. 때로는 마이그레이션을 실행하지 않는 확장자가 txt 인 파일을 생성하기 때문에.

올바르게 작동하려면 파일 확장명을 rb로 바꿔야합니다.
