在安装了 style-loader 和 css-loader后，在component里面引入css文件，报无法找到模块。webpack的配置文件如下：
context: __dirname+'/src',

entry:"./js/index.js",
module:{
    loaders:[{
        test:/\.js?$/,
        exclude:/(node_modules)/,
        loader: "babel-loader",
        query:{
            presets:['react','es2015'],
            plugins:['react-html-attrs'],
        }
    },
    {
        //test:/\.css$/,
        //loader:'style!css-loader?modules&importLoaders=1&localIdentName=[name]__[local]__[hash:base64:5]'
        test: /\.css$/,
        loader: 'style-loader!css-loader'
    }]
},
output:{
    path:__dirname+"/src/",
    filename:"bundle.js"
}

引入css文件如下：
var footerCss = require("../../css/style.css");
export default class ComponentFooter extends React.Component{
render(){

   console.log(footerCss);
   

报错提示如下：

Uncaught Error: Cannot find module "../../css/style.css"

注：src/css下面有footer.css文件
