Node v0.8 NODE_PATH not work?

[ysmood]

I try to add some paths to NODE_PATH environment variable. But it seems not work. Is it a bug of node v0.8?

For example, I have a module named A, I put it at /tmp/A, my current NODE_PATH is /tmp/,/b/, the code below won't work on node v0.8, but works fine with v0.10:

require('A');

How to fix the issue?
