我在已安装的宝石列表中看到了它：

然而，当我尝试使用它时（同样应用程序.js文件在 Windows 7 上对我来说运行良好）——未找到 Node.js 解释器：
# node app.js
-bash: node: command not found
# sudo node app.js
sudo: node: command not found
也没有节点归档于在/usr/本地/bin。
请告知我，如何开始使用已安装的 Node.js？
我感觉这里缺少了一点点。

对于 node.js 项目的所有炒作来说，这个宝石只是一个笑话。
它仅包含 eventmachine gem 并为其添加了一个新别名。

sudo apt-get update
sudo apt-get install nodejs
或者
brew update
brew install node
