我在做一个
sudo gem install mysql
在 OS X 上安装 mysql gem。这失败了,输出如下:
Building native extensions. This could take a while...
ERROR: Error installing mysql:

Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/mysql-2.9.1 for inspection.

知道是什么原因造成的吗?如果有什么不同的话,我已经用自制软件安装了 mysql。
最佳答案
From Apple's Xcode/Clang release notes:
The Apple LLVM compiler in Xcode 5.1 treats unrecognized command-line options as errors. This issue has been seen when building both Python native extensions and Ruby Gems, where some invalid compiler options are currently specified. Projects using invalid compiler options will need to be changed to remove those options. To help ?ease that transition, the compiler will temporarily accept an option to downgrade the error to a warning:
-Wno-error=unused-command-line-argument-hard-error-in-future
ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install GemName
