试图安装pg gem会给我带来错误.
我正在使用使用rbenv / ruby-build构建的Ruby 1.9.3-p125.我使用一键安装程序安装了Postgresql.我可以使用pgAdmin连接到数据库.我的想法已经不多了.
% gem install pg ~

解决方法
不确定以下哪个步骤最终解决了这个问题.但由于提到mu太短,问题在于混合32位和64位二进制文件.
> 1,我安装了这个64-bit version of PostgreSQL
> 2,我卸载了任何旧的Homebrew OpenSSL安装
$brew uninstall openssl
> 3,我用Homebrew安装了64位版本的OpenSSL
$brew install –64-bit openssl
>最后,在安装pg gem时,我将LDFLAGS更改为指向64位版本的OpenSSL
$gem install pg — –with-ldflags=’-L/usr/local/Cellar/openssl/0.9.8s’
