Problem description:

The following problem is an error I encountered when using sass:

*!!vue-style-loader!css-loader?{“sourceMap”:true}!
../../../../vue-loader/lib/style-compiler/index?{“vue”:t
rue,”id”:”data-v-570115ee”,”scoped”:false,”hasInlineConfig”:false}!../../../../vux-loader/src/after-less-loader.js!less-loader?{“so
urceMap”:true}!../../../../vux-loader/src/style-loader.js!../../../../vue-loader/lib/selector?type=style
s&index=0!./index.vue in ./node_m
odules/vux/src/components/alert
/index.vue

Solution Such problems are generally caused by a lack of related dependencies. For this example, carefully read the error message and grasp the keywords, vue-style-loader! css-loader, which means there is a problem when css is parsed.
Therefore, the solution depends on the situation and depends on the CSS language you use, whether it is regular or less or sass.

1. If encountered in

regular, execute

npm install stylus-loader css-loader style-loader --save-dev

2. If encountered in

less, execute

npm install less less-loader --save-dev

3. If you encounter it in

sass, just execute

npm install sass sass-loader --save-dev

to install the dependencies

or

 $npm intall sass-loader --save ; $npm install node-sass --save

If you don’t know, okay, you three Are you going to execute them all?.

Generally this problem will only occur when initializing the configuration. If the project is already intact, it will have been configured in package.json and can be installed directly.
