Same error on ubuntu and node.js 0.10.4

[mscdex]

This module hasn't been updated to use libuv. It is still using libev/libeio directly, which were deprecated in node v0.8.x and now removed in node v0.10.x.

Downgrade to node 0.8 and it works. Module will be updated?

I had the same error after upgrading to node v0.10 from v0.8. Resolved the error by doing the following:

1. upgrade to node v0.10.
2. Do an 'nvm update' to update all installed node modules
3. At this point i was getting some 'module mismatch' errors. Had to do 'npm install' on some of my modules. I believe this reinstalls the modules and their dependendencies.
4. To fix db-mysql module, i then followed the instructions from issue Failure to Install on ArchLinux #98. Make sure you download the latest from the git repository. Doing 'npm install db-mysql' at this point will not pull the latest. After you download the latest source and make the change to package.json as described in Failure to Install on ArchLinux #98, do an npm install from your LOCAL package that you just modified.
