Handlebars precompile type error

问题

I'm getting typeError in my handlebars precompiled templates

After looking around stackoverflow seems the issue is related to compatibility issues between the task compiler and handlebars version.

This is my handlebars version:

$ handlebars -v 2.0.0

$ handlebars postlist.hbs | grep "compiler" },"compiler":[6,">= 2.0.0-beta.1"]

The browser output of : handlebars.compiler_version is 6

I'm guessing this might be my problem but not sure how to upgrade my compiler to drop the beta. (?) [THIS SHOULDN'T BE A PROBLEM SINCE BOTH MATCH]

my grunt tasks doesn't throw any errors and the file is created:

$ grunt handlebars:compile

Running "handlebars:compile" (handlebars) task

1 file created.

Done, without errors.

This is my oneline js: var template = Handlebars.templates['postlist'];

This is the error i'm getting in console.log Uncaught TypeError: Cannot read property 'postlist' of undefined.

Please help!

This is my grunt file:

Found the answer here: https://github.com/gruntjs/grunt-contrib-handlebars/issues/60

handlebars: {
    compile: {
        files: {
            "public/js/templates/templates.js": "public/js/templates/*.hbs"
        },
        options: {
            namespace: 'Handlebars.templates',
            processName: function(filePath) {
                var pieces = filePath.split("/");
                return pieces[pieces.length - 1].replace('.hbs', ''); 
                }
        }
    }
}
