내 PC(Gnu/Linux Fedora 30)에서 정전으로 인해 꺼진 크롤링 프로그램을 실행하고 있었는데 그 후 내 크롤러와 다른 Ruby Gem이 작동하지 않고 다음 오류가 표시됩니다.
Traceback (most recent call last):

또는
$ gem env version

그리고 Gem 버전을 보고 싶을 때:
$ gem -v

내 루비 버전 :
$ ruby -v
ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-linux]
Ruby를 다시 설치한 후에도 아무런 변화가 없었습니다.
