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
