启动server-libq.5.dylib时Ruby on Rails/PostgreSQL - Library not Loaded错误

Question

我有运行Ruby 1.9.2,Rails 3和postgreSQL 8.3的应用程序.它最初设置并使用postgreSQL 9.1,但我卸载了9.1并安装并更改为8.3以确保Heroku共享数据库设置的兼容性.它运行正常,但现在不行

现在,在处理这个应用程序时,当我运行数据库升级时,我收到此错误:

dlopen(/Users/michaeljmccoy/.rvm/gems/ruby-1.9.2-p290/gems/pg-0.12.2/lib/pg_ext.bundle, 9): Library not loaded: libpq.5.dylib
  Referenced from: /Users/michaeljmccoy/.rvm/gems/ruby-1.9.2-p290/gems/pg-0.12.2/lib/pg_ext.bundle
  Reason: no suitable image found.  Did find:

当我尝试运行服务器时,我收到以下错误消息:

    from script/rails:6:in `<main>'

我知道它们是非常相似的错误,可能与丢失的路径有关.但是,当我添加路径到我的.profile文件并重新启动终端窗口时,我得到相同的错误.

您可能需要删除并重新安装pggem,因此它是根据Postgres的正确版本编译的.
