I am pretty sure you don't need to install JDK. For RubyMine to run, all you need is JRE. Unless you are going to do Java development, you don't need JDK.
我很确定你不需要安装JDK。要运行 RubyMine，您只需要 JRE。除非您打算进行 Java 开发，否则您不需要 JDK。
To setup Oracle / Sun JRE on Ubuntu / Mint / Debian, follow the instructions here: https://help.ubuntu.com/community/Java#Oracle_Java_7.
要在 Ubuntu/Mint/Debian 上设置 Oracle/Sun JRE，请按照此处的说明进行操作：https: //help.ubuntu.com/community/Java#Oracle_Java_7。
Personally, I have used the instructions under Script (JRE only)section. Specifically, I installed JRE using the repository mentioned on this site: http://www.duinsoft.nl/packages.php?t=en. Works perfectly.
就个人而言，我使用了Script (JRE only)部分下的说明。具体来说，我使用本站点上提到的存储库安装了 JRE：http: //www.duinsoft.nl/packages.php?t=en。完美运行。

Try installing the Oracle JDK and running RubyMine with that.
