Template precompiler version mismatch

[timols]

I'm seeing the same issue as the following user on Stackoverflow: http://stackoverflow.com/questions/16894417/handlebar-precompile-version-error-in-ember-rc5

I've upgraded my gems, to use the latest versions as described in the readme (and SO question) and am now consistently seeing the following error:

Uncaught Template was precompiled with an older version of Handlebars than the current runtime. Please update your precompiler to a newer version (>= 1.0.0-rc.4) or downgrade your runtime to an older version (== 1.0.0-rc.3).

I've included the first few lines from the js template that is generated:

Ember.TEMPLATES["document-center/app/templates/documents/document"] = Ember.Handlebars.template(function anonymous(Handlebars, depth0, helpers, partials, data) { this.compilerInfo = [3,'>= 1.0.0-rc.4'];
helpers = helpers || Ember.Handlebars.helpers; data = data || {};
var buffer = '', stack1, hashTypes, hashContexts, options, escapeExpression=this.escapeExpression, self=this, helperMissing=helpers.helperMissing;

Which seems to indicate that the compiler version that my template was precompiled with is revision 3, v1.0.0-rc.4 compatible (which is what I'm including).

Any ideas on what I am doing wrong?

Can you please clear your tmp folder and see if that helpers

[timols]

Tried that and it doesn't help.

@timols do you have alternative runtime in your vendor directory (which would get populated due to the result of a bundle exec rails g ember:install --head)? As those would take precedence.

[timols]

I did use rails g ember:install --head and so have an ember.js and ember-data.js file in my vendor directory, nothing else for handlebars.

[stefanpenner]

@timols when did you last run rails g ember:install --head

@stefanpenner About 15min ago.

For reference, I'm using:

Ember:
// Version: v1.0.0-rc.5-7-g610589a
// Last commit: 610589a (2013-06-01 16:12:43 -0700)

Ember Data:
// Version: v0.13-9-g07fbd58
// Last commit: 07fbd58 (2013-06-01 14:33:06 -0400)

[stefanpenner]

Seems like ember-latest on the builds.emberjs.com is at:

// Version: v1.0.0-rc.4-21-g6f3fc24
// Last commit: 6f3fc24 (2013-05-31 15:44:44 -0700)

@fivetanley the s3 sync stuff is your cup of tea, mind looking into this?
[edit] fixed

[stefanpenner]

@timols are you using master ember-rails? or the latest gem release?

[timols]

@stefanpenner Using the latest gem release. Should I switch to using master?

[stefanpenner]

@timols you should likely switch to master... I apparently don't have maintainership of this gem on rubygems.

(cc @tchak @wagenet )

[timols]

Ok, pointing to master seems to have resolved the problem. I no longer get the error.

Thanks @stefanpenner

[stefanpenner]

@timols i'll try and get a gem release out ASAP. It is long overdue.
