When running 'jitsu deploy' on my application, I consistently encounter the following error.

Node version: 0.8.9

$ jitsu deploy

I just started experiencing this issue as well. I'll look into it, but I don't have a lot of time or knowledge of the internals of npm/jitsu.

My guess is that the require-analyzer needs to update its npm version.

Getting the same error here

just got this when trying to run deploy for the first time.

running node 0.8.12
and npm 1.1.63

the next time i ran deploy it worked fine.

I then deleted package.json (and the app from nodejitsu) and tried again. Again it worked fine. Not sure how to reproduce this.

Maybe it has something to do with working on windows and OSX with my node_modules checked into git (sometimes I have to do npm rebuild - but i'm pretty sure i did this before trying to deploy the first time)

I resolved this by adding "node" into the "start" in my package.json

"scripts": {
"test": "echo "Error: no test specified" && exit 1",
"start": "node script.js"

@nwkeeley this resolved too

Assuming this got closed by what @thalesfsp said. Feel free to reopen if that's not the case
