& {} throws unknown error

[nirazul]

I've noticed that a sass file consisting of only &{} throws the following error in node-sass:
{ [Error: unknown] message: 'unknown', status: 5 }

...whereas @{} for example throws:
{ [Error: invalid top-level expression] <...more>

More information about my build:

Executed command:

var sass = require('node-sass');
sass.render({
  file: '/path/to/file/main.scss',
}, function(err, result) {
    console.log(err);
});

Versions:

• node-sass: 3.3.2
• node: 0.12.7
• npm: 2.11.3

Is there anything else I can provide to help?

https://github.com/sass/libsass/wiki/API-Documentation says 5 means "unknown error" :)

Ok, then this is completely libsass related.
What would you propose? File a ticket there as this looks like an error or at least the wrong error code?

I guess it might be sass/libsass#1519 but let me check.

Here's what Ruby Sass says:

Error: Base-level rules cannot contain the parent-selector-referencing character '&'.
        on line 1 of /home/saper/sw/nodes-sass-problems/1120/test.scss
  Use --trace for backtrace.

A kind of fix is in sass/libsass#1524
