我在 Ubuntu 17.10 中安装了 RVM，但是当我尝试安装 Ruby 时出现此错误：
$ rvm install 2.5.0
Searching for binary rubies, this might take some time.

如果我尝试安装 libreadline6-dev，apt-get我会收到此错误：
The following packages have mismatched dependencies:
libreadline6-dev: Depends: libreadline6 (= 6.2-9ubuntu1) but 6.3-8ubuntu8 is to be installed
答案1
以下是我在 Ubuntu 17.10 中解决该问题的方法：
首先，逐个安装所需的依赖项，可以通过执行以下命令完成：
sudo apt install libreadline6
sudo apt install libreadline6-dev
sudo apt install libgmp-dev
sudo apt install software-properties-common
然后按照正常安装说明进行操作：
sudo apt-add-repository -y ppa:rael-gc/rvm
sudo apt update
sudo apt install rvm
source /etc/profile.d/rvm.sh
rvm install 2.5.0
如果您愿意，我可以一步一步分享我所遵循的过程的屏幕截图。
希望能帮助到你。
