春天不起作用。 [未初始化的常量Spring :: SID :: DL]

Question

我無法運行Spring。這是錯誤日誌。

我用：

• 的Ruby 1.9.3-P484
• Rails3.2.17
• 春0.0.10
• OSX 10.9
• rbenv

我試過一些其他的測試。我認爲這個問題具體是1.9.3。

Answer 1

我找到了一個解決方案。

在我的情況下，從鐺改變C編譯器蘋果gcc42後完美工作。 這是我使用的命令。

$ 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

這個問題似乎被限制在一個範圍內的Ruby 1.9.3補丁級別，在Mac上編譯，使用蘋果提供的編譯器。

• 的Ruby 1.9.3-P125，與蘋果的LLVM，春季1.1.3，編譯工作
• 的Ruby 1.9.3-p547（最新穩定在寫作時），LLVM，春季1.1.3 - 失敗。

我有一些最新的穩定的LLVM的Ruby（2.0,2.1.2）補丁。他們工作。

所以，在1.9.3系列的某個時刻，P125之後，春季停止使用LLVM時工作。在某種程度上，至少2.0.0-p481，後來的Ruby版本和次要版本以及微型版本再次開始與LLVM一起工作。 IOW，這看起來像一個Ruby 1.9.3迴歸問題，可能是一個Ruby 2.0.0迴歸問題。我記錄了我在Github上發現的Spring問題。

現在，如果你需要1.9.3，你需要春天在Mac上...宙斯考慮。 ;）

如果改變C編譯器不解決您的問題，這個補丁幫我：https://github.com/pigoz/spring/commit/11804d2fd3dce75e9b236666739cdf5b40934abd

只需找到您的系統上的文件（找到在哪裏彈簧通過bundle show spring安裝）並手動進行更改。
