io uso:

• di Ruby 1.9.3-p484
• Rails3.2.17
• Primavera 0.0.10
• OSX 10.9
• rbenv

Ho provato altri test. Penso che questo problema sia specifico per l'1.9.3.

Answer 1

Ho trovato una soluzione.

Nel mio caso, dopo aver modificato il compilatore c da clang a apple-gcc42 ha funzionato perfettamente. Ecco i comandi che ho usato.

$ 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

Questo problema sembra essere limitato a una gamma di Ruby 1.9.3 livelli di patch, compilate su un Mac, utilizzando l'Apple fornito compilatore.

• Rubino 1.9.3-P125, compilato con LLVM di Apple, primavera 1.1.3, funziona
• di Ruby 1.9.3-P547 (ultima versione stabile al momento della scrittura), LLVM, Primavera 1.1.3 - fallisce .

Ho un paio di patch successive di Ruby (2.0, 2.1.2) all'ultima versione stabile, LLVM. Lavorano.

Quindi, ad un certo punto della serie 1.9.3, dopo p125, la molla smette di funzionare quando si utilizza LLVM. A un certo punto, almeno 2.0.0-p481, versioni successive di Ruby e versioni secondarie, e versioni minuscole, riprendono a funzionare, con LLVM. IOW, sembra un problema di regressione di Ruby 1.9.3, probabilmente un problema di regressione di Ruby 2.0.0. Ho documentato ciò che ho trovato su Github come un problema di primavera.

In questo momento, se hai bisogno di 1.9.3 e hai bisogno di Spring su un Mac ... considera Zeus. ;)

Answer 3

Se cambiare il compilatore C non risolve il problema di questa patch mi ha aiutato: https://github.com/pigoz/spring/commit/11804d2fd3dce75e9b236666739cdf5b40934abd

È sufficiente individuare il file sul vostro sistema (trovare dove la primavera è installato tramite bundle show spring) ed effettuare manualmente la modifica.
