Please check your line #1994 at the original css file that generates this problem, it is usually somewhere inside .tmp folder, depends on your configs.

I got the same problem today, the line that causes same error for me is:
.main-container-fixed .course-pref-col .ctn-course-list .course-table td:nth-child(4) .index-btn:not(.btn-success, .select-preview-positive):hover {...
Seems like csso fails at parsing multiple class inside :not, which is a valid css selector (this is a line from a working code of another project I copy into a new project using gulp & gulp-csso as a placeholder to benchmark gulp, suddenly this line throws an error). Try removing that not-multiple-class selector, csso runs fine.

Wondering what your broken line looks like?

Also, it seems like the main devs for this project are quite busy atm, too many opened issues just makes me consider using alternatives for better consistency..

and then �I check #1 in refer to @marani 's comment below:

Please check your line #1994 at the original css file that generates this problem, it is usually somewhere inside .tmp folder, depends on your configs.

Here is my style below:

@charset "UTF-8";
/*------------------------------------*\
    $ANALYTICS
\*------------------------------------*/
/*!*
 *
 *
 *
 */
/**
 *
 * 
 *

 */

@marani Yep, parser don't support for selector list in :not(). This was added in CSS Selectors Level 4 that's still in draft. As I know, only WebKit developers working on it. But I don't know if any released browser support it. If it's an issue, please, fill the separate issue.

@CristianMR Your example parsing ok.
@sotayamashita Your example parsing ok too.

While old - just want to saw thanks here. I was suddenly getting a screwy error with csso and from the notes here alerted me to possible css stuff = in my case, I had an ":ev" instead of ":even" that seemed to be tripping it up
