has no method 'init'

[whyvez]

Trying to use with Yeoman 1.0.

1. Installed grunt-s3 via npm .
2. Added s3 config section as per documentation.
3. Registered npm task like grunt.loadNpmTasks('grunt-s3');.

When I run grunt s3 I get:

Loading "s3.js" tasks...ERROR

TypeError: Object #<Object> has no method 'init'

Any suggestions?

What happens when you run with grunt s3 -v --stack?

I followed your steps but couldn't reproduce. I think @NickHeiner's suggestion is a good start.

Hi, I got the same error, here's the relevant log portion:

@pifantastic @whyvez the issue is likely double including grunt-s3

yeoman puts this line in:

  require('matchdep').filterDev('grunt-*').forEach(grunt.loadNpmTasks);

and then if you add:

  grunt.loadNpmTasks('grunt-s3');

You'll be loading it twice. Since https://github.com/pifantastic/grunt-s3/blob/master/tasks/s3.js#L27 overwrites the s3 variable it is not idempotent and will throw the error.

Am also seeing this error when used with AngularJS. Removing the line:

grunt.loadNpmTasks('grunt-s3');

sorted the problem. Thanks @nletourneau
