Include an external css file in vuejs

Question

I generated a hello-world project with @vue/cli and now I would want to include an external .css file in my App.vue

Then I tried this:

<template>
  <div id="app">
    <div id="nav">
      <router-link to="/">Home</router-link> |
      <router-link to="/about">About</router-link>
    </div>
    <router-view/>
  </div>
</template>

<style>
@import url("../assets/css/bootstrap.min.css");
@import url("../assets/css/panel-rescue.css");
@import url("../assets/css/animate.css");
</style>

But when I run npm run serve this is showing up:

 ERROR  Failed to compile with 3 errors                                                                                                                                                                                                            2:06:05 PM
These dependencies were not found:

To install them, you can run: npm install --save -!../node_modules/css-loader/dist/cjs.js??ref--6-oneOf-1-1!../node_modules/vue-loader/lib/loaders/stylePostLoader.js!../node_modules/postcss-loader/src/index.js??ref--6-oneOf-1-2!../assets/css/animate.css -!../node_modules/css-loader/dist/cjs.js??ref--6-oneOf-1-1!../node_modules/vue-loader/lib/loaders/stylePostLoader.js!../node_modules/postcss-loader/src/index.js??ref--6-oneOf-1-2!../assets/css/bootstrap.min.css -!../node_modules/css-loader/dist/cjs.js??ref--6-oneOf-1-1!../node_modules/vue-loader/lib/loaders/stylePostLoader.js!../node_modules/postcss-loader/src/index.js??ref--6-oneOf-1-2!../assets/css/panel-rescue.css

Then I installed css-loader npm install -D css-loader and I tried a lot of way to setup it in the app with webpack.config.js and vue.config.js , but anyway that I tried fail.

I took a look to the documentation of vuejs and css-loader I'm lost.

Edit solved: @import url("../assets/css/bootstrap.min.css"); by @import url("./assets/css/bootstrap.min.css");

Answer 1

I solved it: Changed

@import url("../assets/css/bootstrap.min.css");

to

@import url("./assets/css/bootstrap.min.css");

The double . led me to one folder above.

Answer 2

You can try to use :

<style lang="sass">
  @import "@/path/file.css";
</style>

@ is an alias to /src

Answer 3

Please try this method. https://github.com/vuejs-templates/webpack/issues/604#issuecomment-287620657 . If its not work

<script>
import '../assets/css/bootstrap.min.css'

export default {
}
</script>

try this.
