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).
How can I upgrade to this version? 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.
