Rails na serwerze w nowym aplikacji

Question

Mam zainstalowany na OS X 10.10.3: homebrew, narzędzia wiersza poleceń, a następnie zainstalować Ruby przy użyciu rbenv:

ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin14] 
Rails 4.2.2 

gdy tworzę nową aplikację (z domyślnej bazy danych SQLite) i spróbować go uruchomić, mówi:

=> Booting WEBrick 
=> Rails 4.2.2 application starting in development on http://localhost:3000 
=> Run `rails server -h` for more startup options 
=> Ctrl-C to shutdown server 
[2015-06-18 23:11:30] INFO WEBrick 1.3.1 
[2015-06-18 23:11:30] INFO ruby 2.2.2 (2015-04-13) [x86_64-darwin14] 
[2015-06-18 23:11:30] INFO WEBrick::HTTPServer#start: pid=41860 port=3000 

ale w przeglądarce widzę:

500 Internal Server Error

Ktoś ma podobny błąd? jak to rozwiązałeś?

Answer 1

byłem coraz to samo, ale z Rails 4.2.1 i działa na Puma 2.11. 3.

Zauważyłem, że Bundler właśnie ulepszył stojak do wersji 1.6.3. Ustawienie wersji z powrotem na 1.6.2 rozwiązało to dla mnie.

Answer 2

Problem jest tutaj: https://github.com/rails/rails/issues/20624

Aby go rozwiązać, zmiany w Gemfile:

gem 'rack', '1.6.1'
