在 Mac OSX Yosemite 上我已成功安裝節點：
# sudo gem install node

我在已安裝的 gem 清單中看到它：

但是，當我嘗試使用它時（相同應用程式.js檔案在 Windows 7 上運作良好）- 未找到 Node.js 解釋器：
# node app.js
-bash: node: command not found
# sudo node app.js
sudo: node: command not found
也沒有節點文件下/usr/local/bin。
請告訴我，如何開始使用已安裝的 Node.js？
我有一種感覺，這裡缺少了一點點。

對於 Node.js 專案的所有炒作來說，這個 gem 就是一個笑話。
它只包含 eventmachine gem 並為其新增一個新別名。

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