我使用:

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

我尝试了一些其他测试.我认为这个问题是 1.9.3 特有的.

I tried some other tests. I think this problem is 1.9.3 specific.

推荐答案

我找到了解决方案.

就我而言，在将 c 编译器从 clang 更改为 apple-gcc42 后，效果很好.这是我使用的命令.

In my case, after changing the c compiler from clang to apple-gcc42 worked perfectly. Here are the commands I used.

$ 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
