Reactjs 元素未在react中呈现

在名为app.jsx的文件中，我有一个来自组件“atividades”的导入：

从“React”导入React
从“语义ui反应”导入{Container}
从“../atividades/atividades”导入atividades
导出默认道具=>(
睾丸
)

但只有h1正在渲染

这是我的atividades组件：

import React, { Component } from 'react'
import { connect } from 'react-redux'
import { bindActionCreators } from 'redux'

import { Form } from 'semantic-ui-react'
import { addWorkout, searchWorkout } from './workOutActions'
import { Button, Icon } from 'semantic-ui-react'

const workoutOptions = [
    { text: 'correr', value: 'run' },
    { text: 'nadar', value: 'swimming' },
    { text: 'andar de bicicleta', value: 'bike' },
]

class atividades extends Component {

    constructor(props){
        super(props)
    }

    componentWillMount(){
        this.props.searchWorkout()
    }

    render() {

        const { addWorkout, searchWorkout, tempoGasto, tipoTarefa, data} = this.props
        return (
            <div role='form'>
                <h6>Inserir atividade</h6>
                <Form>
                    <Form.Group widths='equal'>
                        <Form.Input fluid placeholder='Tempo gasto' />
                        <Form.Select
                            fluid
                            label='Atividade'
                            options={workoutOptions}
                        />

                        <Button animated='vertical'>
                            <Button.Content hidden>Shop</Button.Content>
                            <Button.Content visible>
                                <Icon name='shop' />
                            </Button.Content>
                        </Button>

                    </Form.Group>
                </Form>
            </div>
        )
    }
}

const mapStateToProps = state => ({tempoGasto: state.workout.tempoGasto, tipoTarefa: state.workout.tipoTarefa, data: state.workout.data})
const mapDispatchToProps = dispatch => 
    bindActionCreators({ addWorkout, searchWorkout }, dispatch)
export default connect(mapStateToProps, mapDispatchToProps)(atividades)

import React，{Component}来自“React”
从“react redux”导入{connect}
从“redux”导入{bindActionCreators}
从“语义ui反应”导入{Form}
从“/workOutActions”导入{addWorkout，searchWorkout}
从“语义ui反应”导入{按钮，图标}
常数工作自动选项=[
{text:'corer'，value:'run'}，
{文本：“纳达尔”，值：“游泳”}，
{文本：'andar de Bicileta'，值：'bike'}，
]
类扩展了组件{
建造师（道具）{
超级（道具）
}
组件willmount（）{
this.props.searchWorkout（）
}
render（）{
const{addcount，searchcount，tempoGasto，tipoTarefa，data}=this.props
返回(
艾维德酒店
商店
)
}
}
const-mapStateToProps=state=>（{tempoGasto:state.workout.tempoGasto，tipoTarefa:state.workout.tipoTarefa，data:state.workout.data}）
const mapDispatchToProps=调度=>
bindActionCreators（{addWorkout，searchWorkout}，dispatch）
导出默认连接（MapStateTrops、mapDispatchToProps）（atividades）

它没有在控制台中显示任何内容，但是元素训练没有渲染，VisualStudio代码表示没有使用导入

React组件的第一个字母必须大写，否则它会认为它是一个内置组件，如div、p或span
