Bug report

postcss-loader will emit warnning when some css has ambiguity. But it will cause unstoppable yellow warning in terminal. It is because postcss-loader custom defined a Waring object and emit it with this.emitWarning

Firstly

how should we fix it?

Only change options for autoprefixer, if postcss returns warnings we print them

The yellow warnings are really ugly.

Not sure what do you mean, yellow is default color for warnings

Even we solve problems with cache you will have these warnings in console until you fix your configuration

Well, thanks a lot. Anyway I can't use it beacuse I currently use node12🥹. Ofcourse I know the yellow is default color for warnings, it's just bothering when seeing it.
