css – React-bootstrap元素没有样式

我正在使用react.js和react-router以及webpack开发webapp.

我想使用react-bootstrap进行样式设置,但我的导航栏似乎没有像这里显示的样式

http://react-bootstrap.github.io/components.html#navbars

这是我的react-bootstrap代码

<Navbar inverse fixedTop>

            <Navbar.Collapse>
            <Nav bsStyle="pills">
              <NavItem  href="#"><Link to="/">{this.state.navMenu[0] }</Link></NavItem>
              <NavItem  href="#"><Link to="/utilities">{this.state.navMenu[3] }</Link></NavItem>
              <NavItem  href="#"><Link to="/main">{this.state.navMenu[4] }</Link></NavItem>
            </Nav>             
            </Navbar.Collapse>
          </Navbar>

这些是依赖关系

"devDependencies": {
"babel-cli": "^6.4.0",
"babel-core": "^6.4.0",
"babel-polyfill": "^6.3.14",
"babel-preset-es2015": "^6.3.13",
"babel-preset-react": "^6.3.13",
"babel-preset-stage-0": "^6.3.13",
"css-loader": "^0.23.1",
"file-loader": "^0.8.5",
"history": "^1.17.0",
"react": "^0.14.6",
"react-dom": "^0.14.6",
"style-loader": "^0.13.0",
"webpack": "^1.12.11",
"webpack-dev-server": "^1.14.1"},

  "dependencies": {
    "bootstrap": "^3.3.6",
    "imports-loader": "^0.6.5",
    "react": "^0.14.6",
    "react-bootstrap": "^0.28.2",
    "react-router": "^2.0.0-rc5"
  }

这是webpack.config文件

var webpack = require('webpack');  
module.exports = {  
    entry: [
      'babel-polyfill',
      'webpack/hot/only-dev-server',
      "./app.js",
    ],
    output: {
        path: __dirname + '/build',
        filename: "bundle.js"
    },
    module: {
        loaders: [
            { test: /\.jsx?$/, loaders: ['react-hot', 'babel'], exclude: /node_modules/},
            { test: [/\.jsx?$/, /\.es6$/], exclude: /node_modules/, loader: 'babel-loader'  },
            { test: /\.css$/, loader: 'style!css' },
        ]
    },
     resolve: {
    // you can now require('file') instead of require('file.coffee')
    extensions: ['', '.js', '.json', '.coffee'] 
    },
    plugins: [
      new webpack.NoErrorsPlugin(),

    ]

};

香港专业教育学院试图要求’bootstrap’,但我收到以下错误:未捕获的ReferenceError:jQuery未定义

任何帮助非常感谢请.

最佳答案 你不应该包含bootstrap,因为它将在你的项目中包含所有bootstrap js文件(它们具有依赖性jquery – 因此你会收到错误).您不需要bootstrap js文件,因为您使用的是react-bootstrap.

要包含bootstrap写入的所有css文件:

import style from 'bootstrap/dist/css/bootstrap.css';

之后,您还会遇到其他装载机的问题.这是因为,引导程序样式也使用其他文件.

安装:

npm install --save-dev url-loader

你必须添加到webpack配置加载器:

{
  test: /\.(png|woff|woff2|eot|ttf|svg)$/,
  loader: 'url-loader?limit=100000'
},

在样式加载器文档页面中,作者建议使用带有css-loader的样式加载器.改变这个:

{ test: /\.css$/, loader: 'style!css' },
