Error in plugin "gulp-sass"
Message:
gulp-sass 5 does not have a default Sass compiler; please set one yourself.
Both the `sass` and `node-sass` packages are permitted.
For example, in your gulpfile:
var sass = require('gulp-sass')(require('sass'));
[07:37:06] The following tasks did not complete: styles
[07:37:06] Did you forget to signal async completion?
请教一下老师上面的提示是什么问题？
尝试过的解决方式：
我直接把 “
var sass = require('gulp-sass')(require('sass'));
”
复制粘贴到 gulpfile.js
再运行 nxp gulp scripts 爆出来下面的错误提示
谢谢！
