【问题描述】：

在 ruby​​ 版本 1.9.3 (rvm) 上执行 mysql2 版本 0.3.11 的捆绑安装或直接 gem 安装时，我收到以下错误。但是当我安装最新版本 0.3.16 时它可以工作。我还包括了我的 gcc 版本以供参考。

gcc 版本

【问题讨论】：

与***.com/questions/26417431/…相同的错误

针对 gcc 打开错误：gcc.gnu.org/bugzilla/show_bug.cgi?id=61407

@Substantial 似乎不是相同的错误。

【参考方案1】：

因此发生错误：

ld: -rpath can only be used when targeting Mac OS X 10.5 or later

尝试像这样指定 OSX 部署目标：

export MACOSX_DEPLOYMENT_TARGET=10.5

【讨论】：

考虑为您的答案添加解释

只需在运行bundle install 之前添加导出即可解决我的情况。 @steamboy——你能把它标记为接受吗（如果它也解决了你的问题）？谢谢@maikonas！

$ MACOSX_DEPLOYMENT_TARGET=10.5 bundle install 为我工作。非常感谢！
