Question

尽管已声明propTypes，但Eslint抛出eslint（react / prop-types）错误。我正在使用eslint-plugin-react

我已经查看了其他两个类似的问题以及lint rule for the proptype，但它们并没有解决我的问题。

import React from 'react';
import { View, Text, TouchableHighlight, StyleSheet } from 'react-native';
import PropTypes from 'prop-types';

const PASTEL_PINK = '#dea5a4';
const PASTEL_BLUE = '#779ecb';

const Buttons = ({ onPressStart, onPressPause, onPressReset, onGoing }) => (
  <View >
    <TouchableHighlight
      onPress={onPressStart}
      disabled={onGoing}
    >
      <Text >{START_TIMER}</Text>
    </TouchableHighlight>
    <TouchableHighlight
      onPress={onPressPause}
      disabled={!onGoing}
    >
      <Text >{PAUSE_TIMER}</Text>
    </TouchableHighlight>
    <TouchableHighlight onPress={onPressReset}>
      <Text >{RESET_TIMER}</Text>
    </TouchableHighlight>
  </View>
);

Buttons.protoTypes = {
  onPressStart: PropTypes.func.isRequired,
  onPressPause: PropTypes.func.isRequired,
  onPressReset: PropTypes.func.isRequired,
  onGoing: PropTypes.bool.isRequired,
};

export default Buttons;

提供道具的家长组件

import React from 'react';

import Container from './components/Container';

        }
      }
      else {

  pauseTimer = () => {

    this.setState({

        second: this.state.initialSecond,
      }
    );
  }

  timesUp = (bool) => {
    this.setState(
      (prevState) => (
        {
          completed: bool,
        }

  optionPressed = () => {

  }

  handleMinuteInput = (text) => {
    // clamp minute between 0 and 60
    // const number = helper.clamp(parseInt(text), 0, 60)
    this.setState(

    this.setState(
      {
        initialSecond: text,
      }
    )
  } 

  render() {
    return (
      <Container>
        <Header onPress={this.optionPressed}/>
          <Logo 
            slogan={'Get studying, the Pomodoro way!'}
            imageSource={'../../assets/pomo-timer-logo-small.png'}
          />
          <Timer 
            minute={this.state.minute}
            second={this.state.second}
            completed={this.state.completed}
            onGoing={this.state.onGoing}
          />
          <Buttons 
            onPressStart={this.startTimer}
            onPressPause={this.pauseTimer}
            onPressReset={this.resetTimer}
            onGoing={this.state.onGoing} // true when not onGoing
          />
          <Inputs 
            inputType={'Work'}
            labelColor={PASTEL_BLUE}
            handleMinuteInput={this.handleMinuteInput}
            handleSecondInput={this.handleSecondInput}
            onGoing={this.state.onGoing}
          />
          <Inputs
            inputType={'Rest'}
            labelColor={PASTEL_PINK}
            // setTimer={this.setTimer}
            handleMinuteInput={this.handleMinuteInput}
            handleSecondInput={this.handleSecondInput}
            onGoing={this.state.onGoing}
          />
      </Container>
    )
  }
}

我不希望这些错误出现，但是确实如此。

道具验证中缺少

'onPressStart' 道具验证中缺少“ onPressPause” 道具验证中缺少“ onPressReset” 道具验证中缺少“ onGoing”

Answer 1

替换

Buttons.protoTypes

使用

Buttons.propTypes

我犯了太多次这个错误

Answer 2

它是propTypes，而不是protoTypes：）

道具验证中缺少功能组件中的道具
