variable '--van-gray-6' is undefined and used without a fallback #254

When I start webpack compilation, Terminal prompts the error shown in the following image. An error means that CSS variables are not defined. How can I deal with this problem

In our case, we would like to get such errors (when using an undefined variable), but we don't get them... what version of this plugin are you using btw?
