pg gem安装错误 - 狮子osx，bundler和rvm

Question

我花了太多的时间试图解决这个问题。

我重新格式化了我的电脑 - 干净的雪豹，比立即升级到狮子。

的Xcode 4.2.1安装

RVM安装

当我安装我的环境我终于得到了捆绑安装，并且它没有试图创建PG宝石。

我已经安装postgresql使用macports（不知道它预装在狮子）。这里以下说明：HTTP：//benscheirman.com/2010/06/installing-postgresql-for-rails-on-mac-os-x跑进更多的错误尝试安装PG宝石：

Make sure that `gem install pg -v '0.12.0'` succeeds before bundling. 

我不停地搜索了stackoverflow，几乎试过了一切。

我删除了MacPorts的版本，然后决定尝试用自制安装：

“酿造安装PostgreSQL”

pg_config给我：

我尝试了所有的出口rvm_archflags的=“ - arch x86_64”类型的解决方案，但似乎没有任何区别。

任何想法，我应该开始？

Answer 1

我不熟悉Brew，但它看起来像你调用的pg_config不是用来配置pg的。

因此，请尝试包括/usr/local/Cellar/postgresql/9.1.2/bin（希望有pg_config那里）到路径并重试。

实际上，输出显示“使用来自/ usr/local/bin/pg_config的配置值” 它应该是Brew路径中的pg_config。我想这是在/usr/local/Cellar/postgresql/9.1.2/bin。
