Question

The operation `#e6a23c minus #111` is deprecated and will be an error in future versions.
Consider using Sass's color functions instead.

最近升级了下，webpack版本到4.4,node-sass 4.13

"sass": "^1.5.1",
"sass-loader": "^7.0.3",
"sass-resources-loader": "^1.3.3",
"scss": "^0.2.4",
"scss-loader": "0.0.1"

告警提示颜色运算要废弃了，我去看了sass文档，没有说明啊，是便宜版本问题吗
