używać:

• Ruby 1.9.3-p484
• Rails3.2.17
• Wiosna 0.0.10
• OS X 10,9
• rbenv

Próbowałem innych testów. Myślę, że ten problem jest specyficzny dla wersji 1.9.3.

Answer 1

Znalazłem rozwiązanie.

W moim przypadku po zmianie kompilatora c z clang na apple-gcc42 działało idealnie. Oto polecenia, których użyłem.

$ rbenv uninstall 1.9.3-p484 
$ which gcc-4.2 
/usr/local/bin/gcc-4.2 
$ CC=/usr/local/bin/gcc-4.2 
$ rbenv install 1.9.3-p484 
$ rbenv rehash

Answer 2

Problem ten wydaje się być ograniczone do zakresu Ruby 1.9.3 poziomy poprawki, skompilowane na komputerze Mac, używając Apple dostarczany kompilatora.

• Ruby 1.9.3-P125, skompilowany z Apple LLVM, Spring 1.1.3, działa
• Ruby 1.9.3-P547 (najnowszej stabilnej w czasie pisania) LLVM, Wiosna 1.1.3 - nie .

Mam kilka późniejszych łat Ruby (2.0, 2.1.2) na najnowszej stabilnej, LLVM. Oni pracują.

Tak więc, w pewnym momencie serii 1.9.3, po p125, Spring przestaje działać, gdy używana jest LLVM. W pewnym momencie co najmniej wersje 2.0.0-p481, późniejsze wersje Ruby i mniejsze wersje oraz małe wersje, zaczną znowu działać z LLVM. IOW, wygląda na to, że problem z regresem w wersji 1.9.3, prawdopodobnie z regresem w języku Ruby 2.0.0. Udokumentowałem to, co znalazłem na Githubie jako wiosenny numer.

W tej chwili, jeśli potrzebujesz wersji 1.9.3 i potrzebujesz Spring na komputerze Mac ... rozważ Zeus. ;)

Answer 3

Jeśli zmiana kompilatora C nie rozwiąże problemu to łatka pomogła mi: https://github.com/pigoz/spring/commit/11804d2fd3dce75e9b236666739cdf5b40934abd

Wystarczy odszukać plik w systemie (dowiedzieć się, gdzie sprężyna jest zainstalowany poprzez bundle show spring) i ręcznie dokonać zmiany.
