包含引导程序 3 时出现 Webpack 错误 [英] Webpack Error while including bootstrap 3

问题描述

我在使用 Webpack 将 bootstrap.css 包含到我的入口 js 文件中时遇到问题.

I'm running into a problem while using Webpack to include bootstrap.css into my entry js file.

我有一个入口js文件，名为app.js，用于加载一个外部css名称app.css和bootstrap css

i have a entry js file, named app.js, which is used to load an external css name app.css and bootstrap css

require("../node_modules/bootstrap/dist/css/bootstrap.css");
require("../css/app.css");

所以 bootstrap lib ，我从 npm 得到它并把它放到 node_modules 仓库中.

So the bootstrap lib , i get it from npm and put it into node_modules repo.

这是我的 webpack 配置

So here is my webpack config

var path = require('path');
var webpack = require('webpack');

module.exports = {
    context: path.resolve('js'),
    entry: ["./app.js"], 
    output: {
        path: path.resolve('build/js/'),
        publicPath: '/assets/js/',  
        filename: "bundle.js"
    },
    devtool: "source-map",
    devServer: {
        contentBase: 'public'
    },
    watch: true,
    module: {
        loaders: [
            {
                test: /\.es6\.js$/,
                exclude: /node_modules/,
                loader: 'babel-loader'
            },
            {
                test: /\.css$/,
                loader: "style-loader!css-loader"
            },
            { test: /\.eot(\?v=\d+\.\d+\.\d+)?$/, loader: "file" },
            { test: /\.(woff|woff2)$/, loader:"url?prefix=font/&limit=5000" },
            { test: /\.ttf(\?v=\d+\.\d+\.\d+)?$/, loader: "url?limit=10000&mimetype=application/octet-stream" },
            { test: /\.svg(\?v=\d+\.\d+\.\d+)?$/, loader: "url?limit=10000&mimetype=image/svg+xml" }
        ]
    },
    resolve: {
        extensions: ['', '.js', '.es6.js']
    }
}

当我运行 webpack 时，发生错误

When i run webpack, there is an error happens

ERROR in ../~/bootstrap/dist/css/bootstrap.css

我在谷歌上搜索但找不到解决方案，有人可以帮忙吗?

I searched on google but cannot find not a solution for this, can anyone help ?

提前致谢

推荐答案

我在导入引导程序时也遇到了一些问题，但这个解决方案对我有用...尝试直接从 entry.js 运行 css-loader

I had some problems importing bootstrap too, but this solution works for me... Try running the css-loader straight from your entry.js

require("!style!css!./node_modules/bootstrap/dist/css/bootstrap.min.css");

然后我从 webpack.config.js 中取消选中它.

Then I've unchecked it from the webpack.config.js.

不知道为什么，但是像从配置中那样运行加载程序对我来说也不起作用:

Dunno why but running the loader like you did from the config doesn't worked for me neither:

/*
        {
            test: /\.css$/,
            loader: "style-loader!css-loader"
        },
*/
