정말 실망스러운 문제가 있습니다. 레이크 가 멍청합니다.
문제가 발생하는 방법은 다음과 같습니다.
$ rails new test_app
$ rails generate scaffold new_scaffold field1:string field2:text
둘 다 잘 작동하지만 내가 이렇게하면
$ rake db:migrate
다음과 같은 오류가 발생합니다.

인터넷에서 비슷한 / 같은 오류가 있는지 살펴 봤는데 사람들은 그 오류를 보았습니다. 아무도 문제를 해결하지 못하는 것 같습니다!
이 문제를 어떻게 해결합니까?
bundle update rake
먼저 해야 했어요 그런 다음로 확인했습니다bundle show rake
. 0.8.7이어야합니다. 그런 다음rake db:migrate
.
