无法使用 rbenv 安装 Ruby 2.2.0

我rbenv从 GitHub 安装：

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

我正在尝试安装 Ruby 2.2.0：

sudo /home/vagrant/.rbenv/bin/rbenv install 2.2.0

我该如何修复它？

以下是日志的最后几行：

您没有安装 zlib。要获得正确的构建环境，请运行以下命令：

Ubuntu/Debian：

apt-get install autoconf bison build-essential libssl-dev libyaml-dev libreadline6-dev zlib1g-dev libncurses5-dev libffi-dev libgdbm3 libgdbm-dev

CentOS/Fedora：

yum install -y gcc openssl-devel libyaml-devel libffi-devel readline-devel zlib-devel gdbm-devel ncurses-devel
