我必须在#app 选择器之后添加@import 规则,否则范围样式将被 Bootstrap 导入取消.我认为有更好的方法可以做到这一点,所以我会在弄清楚后更新我的答案.
I'm new to Vue and webpack in general and I'm having a hard time figuring out how to import things.
I created a fresh Vue project through vue init
I added bootstrap 4 with yarn add bootstrap@4.0.0-alpha.6
In main.js I try to import bootstrap and jquery:
import Vue from 'vue';
import jQuery from 'jquery';
import bootstrap from 'bootstrap';
import App from './App';
import router from './router';
But I get:
window.jQuery = window.$ = $;
does not work
Finally, where and how do I load the Sass such that it's available to the whole app?
解决方案
I was having the same issue and this is what I ended up with however, I didn't use Bootstrap alpha since the beta has since been released.
- Install Bootstrap along with its dependencies, jQuery and Popper.js:
npm install bootstrap@4.0.0-beta popper.js jquery --save-dev
- Edit your
/build/webpack.dev.conf.js
file to add a plugin for jQuery and Popper.js to deal with dependencies (you can read more about that in the Bootstrap docs):
plugins: [
// ...
new webpack.ProvidePlugin({
$: 'jquery',
jQuery: 'jquery',
'window.jQuery': 'jquery',
Popper: ['popper.js', 'default'],
// In case you imported plugins individually, you must also require them here:
Util: "exports-loader?Util!bootstrap/js/dist/util",
Dropdown: "exports-loader?Dropdown!bootstrap/js/dist/dropdown",
// ...
})
// ...
]
- Edit
/src/main.js
to import Bootstrap into the app's entry point:
import Vue from 'vue'
import App from './App'
import router from './router'
import 'bootstrap' // ←
- Edit the App.vue' file's
<style>
portion to import Bootsrap into your app's root css:
<template>
<div id="app">
<img src="./assets/logo.png">
<router-view></router-view>
</div>
</template>
<script>
export default {
name: 'app'
}
</script>
<style>
#app {
font-family: 'Avenir', Helvetica, Arial, sans-serif;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
text-align: center;
color: #2c3e50;
margin-top: 60px;
}
@import'~bootstrap/dist/css/bootstrap.css'
</style>
- Run your Vue app from the CLI
npm start
