將Node.js升級到最新版本 - Upgrading Node.js to latest version

問題：

So, I have Node.js installed and now when I tried to install Mongoosejs I got an error telling me that I don't have the needed version of Node.js (I have v0.4.11 and v0.4.12 is needed). 因此，我已經安裝了Node.js，如今當我嘗試安裝Mongoosejs時，出現一個錯誤消息，告訴我我沒有所需的Node.js版本（我須要v0.4.11和v0.4.12）。

How can I upgrade to this version? 如何升級到此版本？ I suppose I just could install it again with the latest version, but I don't want to do it before I'm sure that my project folders in the folder "node" won't be deleted. 我想我能夠再次安裝最新版本，可是在肯定不會刪除「節點」文件夾中的項目文件夾以前，我不想這樣作。
