Error while compiling Bootstrap

Question

npm

Recently started twist-twirl Bootstrap. I decided to build it myself from the sources using Grunt.
As a result, when grunting , I get this error.
If I understand correctly, then this does not affect the compilation in any way, but the error simply an eyesore to me, and I would like to understand what it is, why and why.

Terminal
