Error when building Gulp ohms in the groove?

When you build the project, Gulp, throws the error "Plumber found unhandled error: SyntaxError in plugin 'gulp-autoprefixer'". what hour I am suffering I can not understand in what business. Already checked the whole css code for errors and "nadopasana quotes or colons" all clear... Tell me how to solve this error

Maybe it's the BOM character at the beginning of the file, maybe problem with line-ending.
If so, you can add pipe plug:
1) to normalize line-ending-ov
2) for discarding the BOM character
