os.cpus() undefined

[Hamms]

I'm using the simple example app.js you give; server.js is just var cluster = require('cluster') cluster('./app').listen(8001)

I get the following error:

$ node server.js 

node.js:116
        throw e; // process.nextTick error, or 'error' event on first tick
        ^
TypeError: Cannot read property 'length' of undefined

It looks like os.cpus() is undefined in if (!this.has('workers')) { this.set('workers', os ? os.cpus().length : 1); }

os should be undefined for node 0.2.x, works fine for me with both version of node :s

[Hamms]

I'm on node 0.4.0; is that the problem?

I should clarify; os is definitely defined, and when I sys.inspect os.cpus, I see { [Function]

  [length]: 0,
  [name]: '',
  [prototype]: { [constructor]: [Circular] },
  [caller]: null }

But it returns undefined when called.

I went ahead and also submitted this here

closing since its a node thing
