将Node.js升级到最新版本 - Upgrading Node.js to latest version

问题：

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，我已经安装了Node.js，如今当我尝试安装Mongoosejs时，出现一个错误消息，告诉我我没有所需的Node.js版本（我须要v0.4.11和v0.4.12）。

How can I upgrade to this version? 如何升级到此版本？ 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. 我想我能够再次安装最新版本，可是在肯定不会删除“节点”文件夹中的项目文件夹以前，我不想这样作。
