ReactNative - pod install 시 `conflicting_dependencies': undefined method `request' for nil:NilClass` 에러

Notifee 라이브러리를 설치 후 pod install 진행 시 다음과 같은 에러가 발생했다. 

( Notifee에 의한 오류인지는 불명확했다. )

Ignoring ffi-1.16.3 because its extensions are not built. Try: gem pristine ffi --version 1.16.3

ruby 버전을 체크해 보니 

ruby -v

 

엄청나게 OS 디폴트 버전인 것 같은 2.7.x 버전이 설치되어 있었다. 

현재 ruby 버전 관리는 rvm에 의존하고 있어서 새로운 버전을 설치하기 위해서 

# 목록 업데이트
rvm get stable 

# 설치 가능한 목록 조회 
rvm list known

설치 가능한 버전을 확인해 보니 다음과 같았다. 

그래서 rvm install 3.0.0을 설치하려 했는데, 패키지를 찾을 수 없다고 메시지가 뜨면서도, 설치 과정은 거쳐서 에러가 발생했다. 

그래서 다른 버전들도 설치해 봤지만 모두 동일한 메시지 오류가 발생했다. 

다른 패키지 버전인 rbenv를 설치하고 해 봤지만 동일한 문제가 발생했고, 

결국 asdf로 설치해서 해결했다. 

# asdf 를 설치해주었다. 
# 참고 https://gorails.com/setup/macos/14-sonoma#ruby
cd 
git clone https://github.com/excid3/asdf.git ~/.asdf
echo '. "$HOME/.asdf/asdf.sh"' >> ~/.zshrc
echo '. "$HOME/.asdf/completions/asdf.bash"' >> ~/.zshrc
echo 'legacy_version_file = yes' >> ~/.asdfrc
exec $SHELL

# ruby 3.3.0 설치
asdf plugin add ruby
asdf install ruby 3.3.0
asdf global ruby 3.3.0

# gem update --system
# 하지만 정상적이지 않아서 project 디렉토리에서 프로젝트 ruby 설정을 해주었다. 
asdf local ruby 3.3.0

이후에 pod install 도 정상적으로 동작하는 것을 확인했다. 

 

여담이지만, 티스토리의 맞춤법 기능은 좋지만, 불편하다. 

몇 번의 맞춤법 검사를 돌리고 더 이상 오류가 발생하지 않아야 정상적으로 처리가 된다. 담당자들은 이 상황을 알까?
