spring不起作用。
我无法运行Spring。 这是错误日志。

我尝试了其他一些测试。 我认为这个问题具体是1.9.3。

如果更改C编译器无法解决您的问题，这个补丁帮助了我： https ： //github.com/pigoz/spring/commit/11804d2fd3dce75e9b236666739cdf5b40934abd
只需在系统上找到该文件（通过bundle show spring找到bundle show spring ）并手动进行更改。
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。 这是我使用的命令。
$ 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

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，与Apple的LLVM，Spring 1.1.3一起编译，可以工作
- 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系列的某些时候，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，再次使用LLVM开始工作。 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。 ;）
