我正在尝试设置我的ubuntu环境，为此我需要安装ruby​​要开始工作，我必须在周五之前拿到：/
我按照指示使用rbenv，我遵循了一步一步的指示，但它不起作用。
我试试看：

git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build

然后

rbenv install rbx-5.0

但我得到了这个错误：

好像一切都坏了。
我已经做到了：https://github.com/rbenv/rbenv/issues/1067
看看我的~/.bashrc

...
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

在ruby构建之前，我还尝试运行此命令： source ~/.bashrc 我怎样才能解决它？
