I am trying to set up the basic aurelia app on windows. I have followed instructions from: http://aurelia.io/get-started.html, which includes:

  1. Installed node js
  2. Installed the gulp using: npm install -g gulp
  3. Installed jspn by using: npm install -g jspm
  4. Then downloaded the sample source code from https://github.com/aurelia/skeleton-navigation/releases to the project folder.
  5. Opened a console and changed to project directory ie. navigation-app
  6. Executed the command : npm install
  7. Executed the command: jspm install -y
  8. Finally launched the server using command: gulp watch

All above steps are completed successfully except step 8, which is giving an error :

E:\aurelia\navigation-app>gulp watch
module.js:338
    throw err;
          ^
Error: Cannot find module 'debug/node'
    at Function.Module._resolveFilename (module.js:336:15)
    at Function.Module._load (module.js:278:25)

    at require (module.js:384:17)

    at Object.Module._extensions..js (module.js:478:10)

    at Function.Module._load (module.js:310:12)
    at Module.require (module.js:365:17)
    at require (module.js:384:17)

I am not getting why it can not find modules. If I install that module manually it gives error message for another module when I try to run : gulp watch

I have also been battling this problem since upgrading Aurelia and related tools to the latest versions. It may be related to path length/depth issues on Windows with the native Module.require.

When I uninstalled the following packages from the project's local node_modules folder and instead installed them in the global NPM cache (which lives at a more shallow directory depth in my case), gulp build started working again:

npm uninstall gulp-babel
npm uninstall browser-sync
npm uninstall karma

npm install -g gulp-babel
npm install -g browser-sync
npm install -g karma
