我想为Heroku构建一个Rails3应用程序。他们使用Postgres作为他们的数据库，所以我通过MacPorts安装了postgres9.0。现在我需要一个postgresgem并且共识是出于性能原因你想要pggem。但是我对我得到的错误感到非常困惑当我尝试在rvm下通过geminstall安装pg时。我已经非常明确地指定了所有postgres目录的位置可以找到但仍然无法完成安装:$envARCHFLAGS='-archx86_64'geminstallpg--\--with-pg-config=/opt/local/var/db/postgresql90/defaultdb/po
我打算为ruby脚本创建一个安装程序，但我希望能够确保机器安装了RVM。有没有一种方法可以完全离线安装RVM并且不引人注目(通过不引人注目，就像创建一个可以做所有事情的脚本而不是要求用户向他们的bash_profile或bashrc添加一些东西)我不是要脚本本身，只是一个关于如何走这条路的快速指针(如果可能的话)。我们还研究了这个很有帮助的问题:RVM-isthereawayforsimpleofflineinstall?但有点误导，因为答案只向我们展示了如何离线在RVM中安装ruby。我们需要能够离线安装RVM本身，并查看脚本https://raw.github.com/wayn

我刚刚为fedora安装了emacs。我想用emacs编写ruby。为ruby提供代码提示、代码完成类型功能所需的工具、扩展是什么？ 最佳答案 ruby-mode已经包含在Emacs23之后的版本中。不过，它也可以通过ELPA获得。您可能感兴趣的其他一些事情是集成RVM、feature-mode(Cucumber)、rspec-mode、ruby-electric、inf-ruby、rinari(用于Rails)等。这是我当前用于Ruby开发的Emacs配置:https://github.com/citizen428/emacs
我的瘦服务器配置了nginx，我的ROR应用程序正在它们上运行。在我发布代码更新时运行thinrestart会给我的应用程序带来一些停机时间。我试图弄清楚如何优雅地重启正在运行的Thin实例，但找不到好的解决方案。有没有人能做到这一点？ 最佳答案 #Restartjustthethinserverdescribedbythatconfigsudothin-C/etc/thin/mysite.ymlrestartNginx将继续运行并代理请求。如果您将Nginx设置为使用多个上游服务器，例如server{listen80;server
