Grunt build error

[fernandofranca]

After an npm install I'm getting this error while trying to build with the provided Grunt file.

$ grunt build
Running "coffee:build" (coffee) task
>> 1 files created.

Running "sass:build" (sass) task
OptionParser::NeedlessArgument: needless argument: --sourcemap=none
  Use --trace for backtrace.
Warning: Exited with error code 1 Use --force to continue.

Aborted due to warnings.

To keep it from crashing due Sass, I've just removed the step from the build array:

    # Tasks
    grunt.registerTask 'build', [
        'coffee:build'
        'concat:build'
        'uglify:build'
        'clean:build'
    ]

Hi @fernandofranca the issue is your version of Sass, I've had the same problem in the past, I recommend you update Sass to the latest version, I'm running Sass 3.4.18 (Selective Steve) currently.

[fernandofranca]

Sure!
I'm with Sass 3.3.0.rc.4 (Maptastic Maple).
Updating right now.
Thanks, @anthonyjb !

No problem - can you confirm that fixes just to be sure :)

[fernandofranca]

Done!
It was my outdated Sass tool.

Thanks for confirming 👍
