我试图运行brew update,我得到一个错误,如果我合并,我的本地更改将丢失.我尝试了我的本地更改(不记得制作任何,但它已经有一段时间了),这让事情变得更糟.
这是输出:

我有一个.rvmrc文件,每当我cd进入项目目录时自动选择一个Ruby版本和gemset .
安装RVM 1.19.0后,我收到一条消息
您正在使用
.rvmrc,它需要信任,它速度较慢且与其他ruby管理器不兼容,您可以切换到.ruby-version使用rvm rvmrc to [.]ruby-version或忽略此警告rvm rvmrc warning ignore /Users/userName/code/railsapps/rails-prelaunch-signup/.rvmrc,.rvmrc将继续作为RVM 1和RVM 2中的默认项目文件,忽略运行所有文件的警告rvm rvmrc warning ignore all.rvmrcs.
我应该继续使用我的.rvmrc文件还是应该切换到.ruby-version文件?哪个是最佳的?有什么后果?
我知道一个图像可以放在一个MD的MD语法中,或者,但是我很难在MD中放置一个SVG代码托管在Github上.
最终使用rails3,并且现在经常更改模型,因此我使用RailRoady生成模型架构图的SVG.我希望将该SVG放入ReadMe.md并显示.当我在本地打开SVG文件时,它确实有效,那么如何让浏览器在MD文件中呈现SVG?鉴于代码在最终确定之前是动态的(看似永远不会),在一个单独的地方托管SVG似乎有点过分,而且我错过了实现这一目标的方法.
我想包括SVG是这里 Github上:https://github.com/specialorange/FDXCM/blob/master/Rails/fdxcm/doc/models_brief.svg
我尝试了以下内容,使用实际图像来验证语法是否正常,只是没有呈现SVG代码:
