Rails consoleでエラーが出た場合

Posted at 2017-01-14

MacでRails consoleをしたらこんなエラーが出た。

bundle exec rails c

Running via Spring preloader in process 33223
/Users/test/workspace/teacher/vendor/bundle/ruby/2.3.0/gems/activesupport-5.0.0.1/lib/active_support/dependencies.rb:293:in `require': dlopen(/usr/local/Cellar/ruby/2.3.1/lib/ruby/2.3.0/x86_64-darwin15/readline.bundle, 9): Library not loaded: /usr/local/opt/readline/lib/libreadline.6.dylib (LoadError)

このコマンドを打ったら、ちゃんと起動しました。

ln -s /usr/local/opt/readline/lib/libreadline.7.0.dylib /usr/local/opt/readline/lib/libreadline.6.dylib
