jekyll build error 발단 및 해결과정

발단1

  • 간만에,, 포스팅이 늘어남에 따라 주제별로 분류해야 겠다는 생각이 들어 폴더를 구분해 포스팅을 이동시켰다.
  • 그 다음 다시 build를 시키려는데 아래 빌드 경고가 떴다.
    Build Warning: Layout 'post' requested in jekyll does not exist.
  • 그리고 _post에 _site폴더가 생기면서 빌드된 파일이 생생되었다 ;
  • 찾아보니 내가 빌드 설정을 한 경로가 잘못되었었다;;
  • https://github.com/benbalter/wordpress-to-jekyll-exporter/issues/37

발단 2

  • 상위경로로가 다시 jekyll build를 실행해보니 이번엔 아래 에러가 떴다..
C:\workspace\wkimdev.github.io\wkimdev.github.io>jekyll build
Traceback (most recent call last):

C:/Ruby25-x64/lib/ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in `require': cannot load such file -- bundler (LoadError)

해결과정

  • 구글링 해보니 번들파일을 설치해야 한다고 하여,, 인스톨을 진행했다.. https://github.com/jekyll/jekyll/issues/5165
Try running:

$ gem install bundler
$ bundle install
$ bundle exec jekyll serve
  • 그런데 bundle exec jekyll serve 후 다시 아래가 떠서 하라는대로 bundle insall를 다시 실행했다.
  
C:\workspace\wkimdev.github.io\wkimdev.github.io> bundle exec jekyll build
Could not find gem 'wdm (~> 0.1.0) x64-mingw32' in any of the gem sources listed in your Gemfile.

  • 설치가 되었다고 확인한뒤 다시 실행해보았다.
  • 잘된다~~ ^__ ㅠ
  • 단 아래와 같이 실행할 경우 다시 LoadError 에러가 떴다.

  • 경로에 bundle install 다시 C:\{USER-DIRECTORY}\wkimdev.github.io>bundle install

  • 그냥 jekyll serve라고만 하면 아래 에러가 뜨면서 되지 않는다. 메세지를 읽어보면, 문제를 해결하기 위해 bundle exec를 같이 써서 실행하라고 한다.

  • 다시 실행하니 잘된다~

결론

  • _post경로가 아닌 ‘상위 경로’에서 jekyll build를 실행해야 한다.
  • jekyll build가 제대로 실행되면 _site폴더에 build된 포스팅들이 생긴다.

자주 포스팅을 안하면 잊어버리니까 정리해둔다.

   
  
 1. 포스팅을 작성한다
 2. _posts의 상위경로로가 아래의 명령어로 build를 실행한다.   
 `bundle exec jekyll build`
 3. 같은 디렉토리에서 아래 명령어로 serve를 띄운다.   
 `bundle exec jekyll serve`
 4. 포스팅이 제대로 반영된게 로컬에서 확인되면 commit!
