【问题描述】：
升级到 Mountain Lion 后，我在使用 Rails 时遇到了很多麻烦。
到目前为止，我尝试解决这些问题并在互联网上搜索了几个小时，以确保我的系统在升级后具有运行 rails 的所有依赖项：
- 我更新了 Homebrew 安装
- 我更新了我的 RVM 安装
- 我安装了 XCode 命令行工具
- 我安装了 GCC as mentioned
- 我将我的 Ruby 版本升级到
ruby 1.9.2p290（2011-07-09 修订版 32553）[x86_64-darwin10.8.0]
- 我的 Rails 版本被验证为 Rails 3.2.6
-
我还发现 Mountain Lion 的 Postgres 存在一些问题，所以我看到 this post 并发现我需要将这一行添加到我的 Bash 个人资料中：
export PATH="/usr/local/bin:/usr/bin:$PATH"
现在我转到我升级之前在 Snow Leopard 上运行良好的 Rails 应用程序，当我在命令行运行 rails s 时出现以下错误：
AM@~/Documents/RailsWS/app0815 >gem install pg

当我转到 Rails 应用程序并尝试 bundle install 时，它在 pg 安装时失败。
【问题讨论】：
-
请注意，您的 Rails 和 Ruby 版本都很旧并且存在已知的安全漏洞。截至目前的最新版本是 Rails 3.2.8 和 Ruby 1.9.2-p320/1.9.3-p194。
-
您是否像我之前在您的（现已删除？）问题中推荐的那样通过自制软件安装了postgres？
-
@Deefour 我不记得看过你的回复。
