Make sure you have the runtimes associated with java. Since you are working with oracle database. Make sure you have these gems (therubyracer,execjs,rubyrhino(or therubyrhino), also make sure you have nod.js installed in your system. After installing these gems you shouldn't have any runtime error.
确保您具有与java关联的运行时。因为您正在使用oracle数据库。确保你拥有这些宝石（therubyracer，execjs，rubyrhino（或therubyrhino）），同时确保你的系统中安装了nod.js.安装这些宝石后，你不应该有任何运行时错误。
