jekyll server でなんか警告が出るようになっちゃったときの備忘録。
環境
- macOS big sur
% ruby -v ruby 2.6.6p146 (2020-03-31 revision 67876) [x86_64-darwin20] % rbenv -v rbenv 1.1.2 % gem -v 3.0.3 % bundle -v Bundler version 2.2.20 % jekyll -v jekyll 4.2.0
症状
gem install したときに、なんかconflictしてるけど上書きしてもええか？と聞かれてyesと言ってしまったら、警告が出るようになってしまった；
% jekyll server /Users/<name>/.rbenv/versions/2.6.6/lib/ruby/2.6.0/fileutils/version.rb:4: warning: already initialized constant FileUtils::VERSION /Users/<name>/.rbenv/versions/2.6.6/lib/ruby/gems/2.6.0/gems/fileutils-1.5.0/lib/fileutils.rb:105: warning: previous definition of VERSION was here /Users/<name>/.rbenv/versions/2.6.6/lib/ruby/2.6.0/fileutils.rb:1267: warning: already initialized constant FileUtils::Entry_::S_IF_DOOR /Users/<name>/.rbenv/versions/2.6.6/lib/ruby/gems/2.6.0/gems/fileutils-1.5.0/lib/fileutils.rb:1284: warning: previous definition of S_IF_DOOR was here /Users/<name>/.rbenv/versions/2.6.6/lib/ruby/2.6.0/fileutils.rb:1540: warning: already initialized constant FileUtils::Entry_::DIRECTORY_TERM /Users/<name>/.rbenv/versions/2.6.6/lib/ruby/gems/2.6.0/gems/fileutils-1.5.0/lib/fileutils.rb:1577: warning: previous definition of DIRECTORY_TERM was here /Users/<name>/.rbenv/versions/2.6.6/lib/ruby/2.6.0/fileutils.rb:1595: warning: already initialized constant FileUtils::OPT_TABLE /Users/<name>/.rbenv/versions/2.6.6/lib/ruby/gems/2.6.0/gems/fileutils-1.5.0/lib/fileutils.rb:1635: warning: previous definition of OPT_TABLE was here /Users/<name>/.rbenv/versions/2.6.6/lib/ruby/2.6.0/fileutils.rb:1649: warning: already initialized constant FileUtils::LOW_METHODS /Users/<name>/.rbenv/versions/2.6.6/lib/ruby/gems/2.6.0/gems/fileutils-1.5.0/lib/fileutils.rb:1694: warning: previous definition of LOW_METHODS was here /Users/<name>/.rbenv/versions/2.6.6/lib/ruby/2.6.0/fileutils.rb:1656: warning: already initialized constant FileUtils::METHODS /Users/<name>/.rbenv/versions/2.6.6/lib/ruby/gems/2.6.0/gems/fileutils-1.5.0/lib/fileutils.rb:1701: warning: previous definition of METHODS was here ...
対応
該当gemをアンインストールすればいいらしい；
% gem uninstall fileutils Successfully uninstalled fileutils-1.5.0
その後アップデート；
% gem update --default Updating installed gems Updating fileutils Fetching fileutils-1.5.0.gem Successfully installed fileutils-1.5.0 Done installing documentation for fileutils after 0 seconds Done installing documentation for fileutils after 0 seconds Updating mimemagic Successfully installed mimemagic-0.4.3 Done installing documentation for mimemagic after 0 seconds Done installing documentation for mimemagic after 0 seconds Gems updated: fileutils mimemagic
他にもいくつかのgemで同様の警告が出ていたので、全てアンインストール；
gem uninstall logger
gem uninstall etc
gem uninstall strscan
gem uninstall forwardable
gem update --default
これでもう警告は出なくなった。
