我的反应原生代码我的PropTypes有问题:

import React, { Component, PropTypes } from 'react';
import { Text } from 'react-native';

export default class Star extends Component {
    render() {
        return ( <Text> Hello </Text> );
    }
}

Star.propTypes = {
    fullStar: PropTypes.string.isRequired,
    halfStar: PropTypes.string.isRequired,
    emptyStar: PropTypes.string.isRequired,
    half: PropTypes.bool,
    count: PropTypes.number,
    size: PropTypes.number,
}

Star.defaultProps = {
    fullStar: "",
    halfStar: "",
    emtyStar: "",
    half: 'true',
    count: 5,
    size: 30,
}

我的错误是undefined不是一个对象(评估'_react2.PropTypes.string')

谢谢你的阅读;)

两个问题，如果我这样绑定我的函数：

deleteTag = (id) => {
  console.log(id);
  id = 0;
  tabTag.splice(id, 1);
  --tabSize;
}

  componentTag() {
   return tabTag.map(function(item, id){
      return(
        <View key={id} style={styles.componentView}>
          <Icon name="ios-reorder"></Icon>
          <Text>{item.name}</Text> 
          <Slider style={styles.sliderBar} maximumValue={3} step={1} />
          <TouchableHighlight onPress={() => this.deleteTag.bind(this)}>
            <Icon name="close-circle"/>
          </TouchableHighlight>
        </View>
      );
    });
  }

我的错误是'无法读取未定义的属性'bind'

其他

如果我将函数绑定到构造函数中，则不会发生任何事情

 constructor(props) {
     this.deleteTag = this.deleteTag.bind(this);
  }

deleteTag = (id) => {
  console.log(id);
  id = 0;
  tabTag.splice(id, 1);
  --tabSize;
}

  componentTag() {
   return tabTag.map(function(item, id){
      return(
        <View key={id} style={styles.componentView}>
          <Icon name="ios-reorder"></Icon>
          <Text>{item.name}</Text> 
          <Slider style={styles.sliderBar} maximumValue={3} step={1} …

自从上次柯南（1.23.0）以来，我无法安装某些软件包，例如我想安装 mysql-connectorc

mysql-connector-c/6.1.11@bincrafters/stable

但我收到了这个错误：
