使用 rbenv 更改所有用户的默认 Ruby

我rbenv在 vagrant 中安装的方式如下：

apt-get update
apt-get install -y automake bison build-essential git-core libffi-dev libreadline6-dev libgdbm3 libgdbm-dev libncurses5-dev libssl-dev libtool libyaml-dev vim zlib1g-dev
[ -e /bin/rbenv ] || {
    git clone git://github.com/sstephenson/rbenv.git ~/.rbenv
    git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
    ln -s ~/.rbenv/bin/rbenv /bin/rbenv
    rbenv install 2.2.0
    rbenv global 2.2.0
}

问题是：

root@vagrant-ubuntu-trusty-64:~/.rbenv# cat version
2.2.0
root@vagrant-ubuntu-trusty-64:~/.rbenv# ruby -v
ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux]

我如何为所有用户安装 2.2.0 作为默认 Ruby？

我找到了一种解决方法：

apt-get update
apt-get install -y automake bison build-essential git-core libffi-dev libreadline6-dev libgdbm3 libgdbm-dev libncurses5-dev libssl-dev libtool libyaml-dev vim zlib1g-dev

[ -e /opt/ruby-build ] || {
    git clone git://github.com/sstephenson/ruby-build.git /opt/ruby-build
    /opt/ruby-build/bin/ruby-build 2.2.0 /opt/ruby-2.2.0
    echo PATH="/opt/ruby-2.2.0/bin:\$PATH" >> /etc/profile
    PATH="/opt/ruby-2.2.0/bin:$PATH"
}
