Error with 3.3.0.rc.2: NoMethodError: undefined method `tabs' ...

[Fernker]

I recently switched to RC2 and in one of my files I'm getting the following error. Even though this file was working before (with a previous pre version). I have had a question up on StackOverflow without any bites.

NoMethodError: undefined method `tabs' for Sass::Tree::CommentNode:Sass::Tree::CommentNode

Using --trace I get the following:

What's the contents of the Sass file you're trying to compile?

[Fernker]

Do you want me to post the entire thing? (It's 1700 lines long)

[nex3]

Ideally, narrow it down to as small as you can get it where it still produces the error in question.

[Fernker]

Ok I was able to narrow it way down to this chunk of code below. I was able to pull this chunk out and the file compiled fine. I put the chunk in a new file and tried to compile it and got the error mentioned above.

.test{
@at-root{
        #{&}__btns{
            display:block;
            float: right;
            top: 28px;
            margin-top: -28px;
            position: relative;
            z-index: 6;
            .btn.btn--icon{
                margin-left: 7px;
            }
        }
        /* For the Top Chatter Area, it's special */
        #{&}--chatter{
            position: absolute;
            z-index: 9;
            margin-top: 0;
            textarea{
                width: 100%;
            }
        }
    }
}

[Fernker]

Did some more digging. It's the CSS comment in there. I imagine that's because it is in an @at-root without actually being in a declaration. If I switch it from /* to // the problem seems to go away.

[chriseppstein]

I reproduced it. @nex3, the problem is that we need to add a :tabs accessor to the comment node.
