###### WARNING:
Removing `Gemfile.lock` because it was generated on Windows.
Bundler will do a full resolve so native gems are handled properly.
This may result in unexpected gem versions being used in your app.
In rare occasions Bundler may not be able to resolve your dependencies at all.

The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.

Все, разобрался. Предупреждениям надо уделять внимание, но они не так критичны. После деплоя на хероку сайт выдавал ошибку которая на ранних этапах в localhost появлялась если вы не делали rake db:migrate. Тут все исправилось командой heroku run rake db:migrate.
