ruby-on-rails – Rails上的Ruby / PgSQL错误启动：无法加载此类文件 – pg_ext(LoadError)

我是 Ruby的新手(来自Java背景)并且可以从 Git存储库访问RoR项目.我能够通过自制软件安装rbenv和Postgres构建Ruby,使用正确的标志安装“pg”gem.我在项目上做了“捆绑安装”的任何方式,当我去启动服务器时,它创建了一个捆绑包……任何帮助都将是绝对值得赞赏的！

解决方法

问题也出现在Fedora 17中.

卸载“pg”gem：

gem uninstall pg

运行bundle(假设Gemfile包含“pg”gem)：

bundle
