安装jekyll准备环境

问题1 i386sudo

在准备安装ruby时一直报错，提示apt-get 命令有问题

然后我执行了一下sudo apt-get update 确实出现了如下问题

解决这个问题的过程很艰辛，下面只说最后结果：

去掉软件和更新中的勾选：有版权和合法性问题的软件
在/etc/apt/目录下找到更新源文件，注释掉第三方的源，类似上面“http://dl.google.com/..”的源。
系统架构中删除i386sudo

dpkg –print-foreign-architectures
dpkg –remove-architecture i386sudo

删除sudo 后重新执行命令 sudo apt-get update 成功！

问题2 rvm is not a function

安装jekyll时会提示rvm is not a function 参考 https://ruby-china.org/topics/3705 https://rvm.io/integration/gnome-terminal 在terminal中勾选“以登陆shell方式允许命令”后重启terminal就可以继续了。
