我用:

• Ruby 1.9.3-p484
• Rails3.2.17
• 春天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,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(找到安装弹簧的位置bundle show spring)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.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
