1、vue-loader报错

报错详情
vue-loader 17.0.0运行webpack打包命令时会报错：

解决方法：
需适配版本：将package.json，vue-loader版本修改为 “vue-loader”: “^15.10.0”，删除本地node_modules文件夹，重新运行即可

2、gulp打包css报错

报错详情

Error in plugin “gulp-sass” Message:

gulp-sass no longer has a default Sass compiler; please set one
yourself. Both the “sass” and “node-sass” packages are permitted. For
example, in your gulpfile:

const sass = require(‘gulp-sass’)(require(‘sass’));

[09:54:33] The following tasks did not complete: sass [09:54:33] Did
you forget to signal async completion?

解决

按报错信息说的将 const sass = require('gulp-sass') 改为

const sass = require('gulp-sass')(require('sass'));
