Best is to install it using rvm(ruby version manager).
Run following commands in a terminal:

在终端中运行以下命令：
sudo apt-get update
sudo apt-get install build-essential make curl
\curl -L https://get.rvm.io | bash -s stable
source ~/.bash_profile
rvm install ruby-2.1.4
Then check ruby versions installed and in use:
然后检查安装和使用的 ruby 版本：
rvm list
rvm use --default ruby-2.1.4
Also you can directly add ruby bin path to PATH variable. Ruby is installed in

Use RVM(Ruby Version Manager) to install and manage any versions of Ruby. You can have multiple versions of Ruby installed on the machine and you can easily select the one you want.
使用RVM（Ruby 版本管理器）来安装和管理任何版本的 Ruby。您可以在机器上安装多个版本的 Ruby，并且您可以轻松地选择您想要的版本。
To install RVM type into terminal:

\curl -sSL https://get.rvm.io | bash -s stable
And let it work. After that you will have RVM along with Ruby installed.
让它发挥作用。之后，您将安装 RVM 和 Ruby。
