Which version of Node.js should I choose
express, formidable, node.js
Solution
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.
Problem
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)?
