I get the following error while running the sample, Please help.

debundle -i bundle.js -o dist/ -c debundle.config.json

@wongchichong I just ran through the example again, it works for me. What's in your debundle.config.json? What node version are you running? Do the md5sums of the files match the md5sums I calculated in the logs below?

Just update the node.js version, still had the same error. PS. I'm running on windows 10.

@wongchichong Ah, you're on windows. Debundle doesn't support windows right now mostly because I don't have a windows machine to try and replicate problems and there are lots of hard-coded forward slashes all over the place.

I ran into this issue on my Mac (both node v6.11.2 and v10.5.0) , and the trouble was a path that started with ../ (it was from this line in my code: var ngApp = require('../_ng/setup');)

The clue was in getModuleLocation.js:

// If a filePath has a bunch of `../`s at the end, then it's broken (it broke out of the dist
// folder!) In this cae, tell the user we need an absolute path of one of the files in order to
// resolve it. Log out each of the paths along the require tree and it's respective module id.

To resolve it, I mapped it to another path in the knownPaths parameter; this was my config file:

{
  "type": "browserify",
  "knownPaths": {
    "61": "./_ng/setup"
  }
}

It is also a massive file (beautified, it's 48796 lines of code!) so the error didn't happen until the very end, after it had run for 20min 😭
