I am planned to build a web application based on Node.js. As a common sense I installed the latest version of Node.js (v0.10.0). I was also suggested to use express.js to avoid use low level APIs.
When I was trying to install express.js package, I found it could not be installed becase some dependices are missing. So, I tried to install all missing dependices one by one. All packages are OK for installation except formidable.js which requires node.js version to be less than 0.9.0("node": "<0.9.0")}. I was frustrated, because for my new development I would like to use the newest stalbe version of Node.js rather than choose a very early version (0.9.0).
So, if I still want use express.js, should I really roll back my node.js to an earlier version (<0.9.0)?
Node 0.10.0 is relatively new and many frameworks and libraries do not support this version yet.
Node 0.9.x was an unstable release as every odd-numbered version (every even numbered version is considered stable, e.g., 0.6.x, 0.8.x, 0.10.x, ...).
For starting you might use the latest 0.8.x version and upgrade to 0.10.x later as libraries evolve.
The node versioning schema may be found here: https://github.com/joyent/node/wiki/FAQ#what-is-the-versioning-scheme
Hint: There is the tool Nave which allows you to use several node installations at once.
Meanwhile Node 0.10.x is very stable and should be chosen.
