Generator throws error during scaffolding

[bchu]

The generator throws an error mid-way through scaffolding an angular app, then continues on. I'm not sure if that's supposed to happen, and I'm not sure whether that has anything to do with the lack of e2e tests in the resulting app.

yo angular --minsafe
.... (some stuff)
   invoke   karma:app
   create     karma.conf.js
   create     karma-e2e.conf.js

events.js:130
    throw TypeError('listener must be a function');
          ^

Some of your dependencies are outdated. Can you try a fresh install?

[bchu]

I tried a fresh install with:

node v0.8.23, then running npm -g update npm, then npm -g install yo grunt-cli bower, then npm -g install generator-angular, then yo angular. The same error emerges.

Also tried
node v0.10.8, then npm -g install yo grunt-cli bower, then npm -g install generator-angular, then yo angular, and the same result. Same for when I directly try yo karma.

same issue here on node v0.10.8
but, it does work on v0.8.15

[passy]

This is a bug we fixed before, so it must be some stale dependency. Did you run npm cache clean before reinstalling?

[oori]

Yes, it did the trick. npm cache clean. (just in case,uninstalled them before..)
Thanks!

[passy]

@bchu Does this work for you, too?

[bchu]

Very weird. I was running npm cache clean before and it didn't work. But for some reason it is working now. It would seem that it can be important when (at what stage) you run npm cache clean.

But it works now.

[eddiemonge]

at what stage is the correct place to run it? i installed node and npm fresh along with yo, grunt-cli and bower and am getting this on a fresh checkout

[bsphere]

I'm also getting this issue after npm cache clean and fresh install of yo bower grunt-cli and generator-angular

same here the whole day wasted... cleaned all cache and reinstalled eveything just wont work.

events.js:130
throw TypeError('listener must be a function');
^

[bchu]

Try uninstalling the generators and yo/grunt/bower, then npm cache clean, then install yo/grunt/cli, then npm cache clean, then install generator-, then npm cache clean, then yo <whatever>

[bsphere]

doesn't help.. same problem

This was fixed with the v0.3.1 release of generator-karma yesterday.

[islandmanllc]

I've spent 3 hours trying to get this to work but still get the same error.

I've tried with Node 0.8.15, 0.8.25, 0.10.15
npm install -g yo grunt-cli bower
npm install -g angular

events.js:130
throw TypeError('listener must be a function');

I'm about to give up on this because it's quickly becoming very costly. Can anyone please list a valid configuration?

Node version and 32/64 bit?
Installation instructions 1...n including the need for clearing cache

Thanks,

[btford]

[islandmanllc]
