gem install pg错误：无法理解Yosemite上的kern.osversion`14.0.0'w / Ruby 2.1.5 [英] gem install pg error: couldn't understand kern.osversion `14.0.0' on Yosemite w/ Ruby 2.1.5

问题描述

我使用RVM安装Ruby-2.1.5并再次运行软件包。现在pg gem不会安装，我得到这个错误：

  gem install pg -v'0.17.1' - --with-pg-config = / Applications / Postgres.app / Contents / Versions / 9.3 / bin / pg_config 
使用'--with-pg-config = / Applications / Postgres.app /目录构建原生扩展/Versions/9.3/bin/pg_config'
这可能需要一段时间... 
错误：安装pg时出错：
错误：无法构建gem本机扩展。

我通过App Store更新了XCode到6.1版。我通过自制软件重新安装了gcc和applegcc-4.2。我也重新安装Postgres.app。我已经尝试了建议的解决方案这里和 here 无济于事。

任何人都知道接下来要做什么？现在我只是恢复到Ruby-2.1.4，其中pg安装正常。 如果将<$ c $在编译 pg gem之前，在您的环境中使用c> MACOSX_DEPLOYMENT_TARGET = 10.9 ，共享对象链接应该可以正常工作。

I used RVM to install Ruby-2.1.5 and ran bundle again. Now the pg gem won't install and I get this error:

I've updated XCode to version 6.1 via the App Store. I reinstalled gcc and applegcc-4.2 via homebrew. I also reinstall Postgres.app. I've tried the suggested solutions here and here to no avail.

Anybody have any idea what to try next? For now I'm just reverting to Ruby-2.1.4 where pg installs fine.

解决方案

If you set MACOSX_DEPLOYMENT_TARGET=10.9 in your environment prior to compiling the pg gem, the shared object linking should work properly.
