Local build fails

[habernal]

After installing dependencies

bundle config --local path vendor
bundle install

I got in some trouble...

habi@desktop:~/PycharmProjects/inception-project.github.io$ bundle exec jekyll serve --config _config.yml,_config_dev.yml

Hm, maybe I should check in the Gemfile.lock...?
