我用：

Ruby 1.9.3-p484
Rails3.2.17
春季0.0.10
OSX 10.9
rbenv

我尝试了其他一些测试。我认为这个问题具体是1.9.3。

Answer 1

如果更改C编译器无法解决您的问题，那么这个补丁帮助了我：https://github.com/pigoz/spring/commit/11804d2fd3dce75e9b236666739cdf5b40934abd

只需在您的系统上找到该文件（通过bundle show spring查找安装弹簧的位置）并手动进行更改。

Answer 2

我找到了解决方案。

在我的情况下，将c编译器从clang更改为apple-gcc42后效果很好。以下是我使用的命令。

$ 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 3

此问题似乎仅限于使用Apple提供的编译器在Mac上编译的一系列Ruby 1.9.3补丁级别。

Ruby 1.9.3-p125，使用Apple的LLVM编译，Spring 1.1.3，正常工作
Ruby 1.9.3-p547（编写本文时最新稳定版），LLVM，Spring 1.1.3 - 失败。

我在最新稳定的LLVM上有几个后来的Ruby补丁（2.0,2.1.2）。他们工作。

因此，在1.9.3系列中的某个时刻，在p125之后，Spring在使用LLVM时停止工作。在某些时候，至少2.0.0-p481，后来的Ruby版本和次要版本，以及小版本，再次开始使用LLVM。 IOW，这看起来像Ruby 1.9.3回归问题，可能是Ruby 2.0.0回归问题。我已经记录了我在Github上发现的Spring问题。

现在，如果你需要1.9.3并且你需要Mac上的Spring ...考虑Zeus。 ;）
