syntax error in _wvu-slash.scss

[architarious]

Description of problem

I keep getting the following error whenever I try to compile.

Generating JavaScript bundles failed

Parse error on line 1:
-25% + -(1 * 2rem)
--------^
Expecting "SUB", "NUMBER", "LENGTH", "ANGLE", "TIME", "FREQ", "RES", "EMS", "EXS", "CHS", "REMS", "VHS", "VWS", "VMINS", "VMAXS", "PERCENTAGE", "css_value", got unexpected "LPAREN"

How to fix it

I narrowed it down to either line 82 or 92 in scss/utilities/_wvu-slash.scss, and then made the following changes and it worked fine.

Change these lines
82: left: -($i * $spacer) $global-important;
92: top: calc(-25% + -(#{$i} * #{$spacer})) $global-important;

To this:
82: left: ($i * $spacer)*(-1) $global-important;
92: top: calc(-25% + (#{$i} * #{$spacer})*(-1)) $global-important;
