only some vue component's style wouldn't extract into css file

[oliver1521314]

this is the code of vue file

<template>
	<div id='userManagePart'>	
		<div>
			<con-title>用户管理</con-title>
		</div>
		<el-row>
			<el-col :span="5">
				<div>
				 <teemTree></teemTree> 	
				</div>		
			</el-col>
			<el-col :span="19">
				<div>
					<userDataList></userDataList>
			    </div>
			</el-col>
		</el-row>
	</div>
</template>

Only the style markup of teemTree component wouldn't be extract into css file ,But the style of userDataList component is ok , I check the two components ,they are just the same.

Below is the code of teemTree component:

<template>
	<div class="teem-tree">
		<div class="teem-tree-title">部门</div>
		<div class="tree">
			<el-tree
			  	:data="treeD"
			  	node-key="deptId"
			  	accordion default-expand-all
			  	:highlight-current="rowSelect"			  	
			  	:expand-on-click-node="false"
			  	@node-click="TreeClick"
			  	:props="defaultTreeProps">
			</el-tree>
		</div>
	</div>
</template>

<script>
	import {vueEle} from '../common/js/vueBus.js'
	export default {
		data() {
			return {
				rowSelect:true,
		        defaultTreeProps:{
		        	children:'childList',
		        	label:'deptName'
		        }
			}
		},
		props:['treeD'],
		methods:{
		    TreeClick(data){
		    	if(data.deptId!=null){
		    		vueEle.$emit('deptChange',data.deptId);
		    		this.rowSelect=true;
		    	}		    
		    }
		},
		filters:{
			formatIndex(_val){
				return 	'2-'+_val
			}
		},
		created(){
			vueEle.$on('ChangeStyle',(changevalue)=>{
				this.rowSelect=changevalue;
			})
		},
		mounted(){
			console.log(this.treeD)
		}
	}
</script>


<style  scoped>
	.teem-tree{
		border-radius: 4px;
	}
	.teem-tree-title{
		padding: 0 15px;
		line-height: 30px;
		background-color: #5f9b69;
		color: #fff;
	}
</style>

the webpack config is below:

 module: {
    rules: [
      {
        test: /\.vue$/,
        loader: 'vue-loader',
        options: {
		  loaders: {
		    css: ExtractTextPlugin.extract({
		        use: loaders,
		        fallback: ['vue-style-loade']
		     })}
		}
      },
      {
        test: /\.js$/,
        loader: 'babel-loader',
        include: [resolve('src'), resolve('test')],
        query: {
          presets: ['es2015']
        }
      },
      {
        test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
        loader: 'file-loader',
        query: {
          limit: 8000,
          name: utils.assetsPath('img/[name].[hash:7].[ext]')
        }
      },
      {
        test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/,
        loader: 'url-loader?limit=10000&name=static/fonts/[name].[ext]',//?limit=10000&'+ urlname
//      query: {
//        limit: 8000,
//        name: utils.assetsPath('fonts/[name].[hash:7].[ext]')
//      }
      }
    ]

I think you have a typo in webpack.config.js:

fallback: ['vue-style-loade']

shouldn't it be vue-style-loader?
