我正在尝试将我的 ruby 从包管理器2.5（当前）安装的 ruby 升级到2.6using snap. 我就是这样做的
sudo snap install ruby --classic
/usr/bin/ruby符号链接到包管理器安装的 stable ruby。去掉它。
sudo rm /usr/bin/ruby
确保您的 PATH 环境变量包括/snap/bin
现在我要删除包管理器安装的 ruby。
$ sudo apt remove --purge ruby

基本上删除ruby意味着删除整个系统。无论如何以透明的方式替换 ruby，我不会被迫删除所有这些包？如果我用最新的系统推荐的红宝石替换snap系统稳定性会降低多少？
