Mountain Lion上的pg gem'0.14.0'失败了

Question

我刚从OS X Lion升级到OS X Mountain Lion.我的铁路环境大部分都保持着机智.

我必须做的唯一步骤是让事情恢复到良好状态: - 安装XCode 4.4 - 安装XCode 4.4命令行工具 - 安装gcc-4.2

一切顺利.

这是问题,当我运行bundle install时几乎所有的gem都安装正确,除了我需要的最重要的一个 - postgresql gem'pg'.

它特别适用于0.12.2以上的版本.

我正在使用ruby 1.9.3p125.

我可以成功获取0.12.2 pg宝石,以及下面的版本,但它们给我分段错误(我猜是因为我正在使用的ruby版本).

因此,这让我相信它特定于pg gem,而不是我的整体环境看到其他宝石安装正常.

我也尝试重新安装Postgresql以确保我的postgres环境没问题,并且在这方面似乎很好.

有没有人能够安装'pg'宝石版0.13.0或更高版本(更优选0.14.X)？

这是我的堆栈跟踪:

Answer 1

Deefour的评论得到了它!这是我安装PostgreSQL的方式.

我使用PostgreSQL一键安装程序,我猜测它没有为Mountain Lion正确设置libpq.

另一方面,Homebrew将为操作系统正确构建它.

通过自制软件安装postgres后

brew install postgresql

我能够安装我的宝石没问题.

谢谢大家!

Answer 2

问题是pg_config的位置.如果你使用一键安装程序,它在/Library/PostgreSQL/9.2/bin/pg_config中,所以这将构建你的gem就好了:

env ARCHFLAGS =" - arch x86_64"gem install pg - --with-pg-config =/Library/PostgreSQL/9.2/bin/pg_config

Answer 3

重新安装 ruby​​ 解决了升级到 Mountain Lion 后遇到的类似问题

rvm reinstall 1.9.3

注意：还运行以下命令，因为默认版本似乎已重置

rvm --default 1.9.3

作为参考，我发布了我在下面看到的错误

gem install pg
