在ubuntu-20.04.3下安装ruby

最近开始学习ruby，ruby基础在此之前已经学习的差不多了，不过都是在windows上操作，但经过来人告诉我，建议我在linux上学习ruby，因为windows上对ruby的依赖很混乱。我选择ubuntu-20.04.3来进行学习。

从 Ubuntu 源仓库安装 Ruby
这个方式相比之下是比较简单的。以 root 或者其他有 sudo 权限的用户身份来运行下面的命令，来升级软件包索引，并且安装 Ruby：

sudo apt update
sudo apt install ruby-full

命令输出如下：

niufei@niufei-Virtual-Machine:~/Desktop$ sudo apt update

安装完成之后，通过打印版本号来验证安装结果：

ruby --version

命令输出如下：

niufei@niufei-Virtual-Machine:~/Desktop$ ruby --version
ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-linux-gnu]

如果出现版本号，说明安装成功，可以使用ruby了。安装版本有差异是正常的。
