我已尝试多次安装Sencha命令行工具，但我仍然卡住了。这是我命令行的输出。
$ projects/sencha-touch-2.2.0 → sencha
node.js:201
throw e; // process.nextTick error, or 'error' event on first tick
^

ruby 2.0.0p195 (2013-05-14 revision 40734) [x86_64-linux]
我在不同的论坛上发现我需要SDK工具的3+版本，但我能为Linux获得的唯一下载标记为SenchaCmd-3.1.2.342-linux-x64.run，我希望它是正确的安装文件。
请帮我解决一下我的操作系统问题？ [Linux Mint 14（Ubuntu 12.x）]
