Ruby 버전 업 후 오류

왜 문제가 발생했나요?

다른 PC에 git clone 후 로컬에서 테스트를 위해 ruby를 기존(3.2.4)보다 최근 버전(3.3.6)으로 설치했습니다. jekyll serve 명령 후 아래와 같은 오류가 발생했습니다.

C:/Ruby33-x64/lib/ruby/gems/3.3.0/gems/bundler-2.6.2/lib/bundler/resolver.rb:354:in raise_not_found!': Could not find gem 'wdm (~> 0.1.1) mingw, x64_mingw, mswin' in locally installed gems. (Bundler::GemNotFound)

The source contains the following gems matching 'wdm':

어떤 문제인가요?

오류 메세지를 보시면 뭔가 wdm 버전 관련해서 뭐라고 하는 것 같죠? 저도 그렇게 생각했습니다. 찾아보니 ruby의 wdm이라는 gem 버전이 맞지 않아서라고 합니다.

어떻게 해결했을까요?

저의 경우 아래와 같이 Gemfile의 내용을 기존 0.1.1에서 0.2.0으로 수정 후 정상 작동을 확인했습니다.

# (생략...)

# Performance-booster for watching directories on Windows
gem "wdm", "~> 0.2.0", :platforms => [:mingw, :x64_mingw, :mswin]

# (생략...)

감사합니다.
