无法安装pg gem
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。

- 1，我安装了这个64位版本的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位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’
