未定义的对象不是_react.PropTypes.array。

Question

我正在使用React本地(世博会CLI)。由于我重新安装了npm，所以当我尝试运行npm start时，我发现了一些与react-native-snap-carousel相关的类似错误(我正在使用它)。

TypeError: undefined is not an object (evaluating '_react.PropTypes.array')    
at node_modules\expo\build\environment\react-native-logs.fx.js:27:4 in error   
at node_modules\react-native\Libraries\Core\ExceptionsManager.js:95:4 in reportException
at node_modules\react-native\Libraries\Core\ExceptionsManager.js:141:19 in handleException

因此，在它的主文件中导入{PropTypes} from "react";并更改为import PropTypes from "prop-types"; (以前安装)。还将propTypes.items: PopTypes.array.isRequired更改为propTypes.items:PropTypes.array，也更改为slideStyle (因为我开始获得与items和slideStyle相关的新错误是必需的)，但现在我收到了这样的新错误

。所有错误都与react-native-snap-carousel相关

这是我的package.json

下面是我如何使用react-native-snap-carousel

import React, { useState, useEffect } from "react";
import {
  View,
  StyleSheet,
  Image,
  Dimensions,
  TouchableWithoutFeedback,
} from "react-native";
import { getBannersApi } from "../../Api/HomeBanner";
import Carousel, { Pagination } from "react-native-snap-carousel";
import { size } from "lodash";
import { useNavigation } from "@react-navigation/native";

import { SERVER_RESOURCERS } from "../../Utils/Constans";

const width = Dimensions.get("window").width;
const height = 160;

export default function Banner() {
  const [banners, setBanners] = useState(null);
  const [banneActive, setBanneActive] = useState(0);
  const navigation = useNavigation();

  useEffect(() => {
    (async () => {
      const response = await getBannersApi();
      setBanners(response.data);
    })();
  }, []);

  const goToProduct = (id) => {
    navigation.push("product", { idProduct: id });
  };

  if (!banners) return null;

  const renderItem = ({ item }) => {
    return (
      <TouchableWithoutFeedback
        onPress={() => goToProduct(item.attributes.product.data.id)}
      >
        <Image
          style={styles.carousel}
          source={{
            uri: `${SERVER_RESOURCERS}${item.attributes.banner.data[0].attributes.formats.small.url}`,
          }}
        />
      </TouchableWithoutFeedback>
    );
  };

  return (
    <View style={styles.container}>
      <Carousel
        layout="default"
        data={banners}
        sliderWidth={width}
        itemWidth={width}
        renderItem={renderItem}
        loop={true}
        onSnapToItem={(i) => setBanneActive(i)}
        autoplay={true}
        autoplayInterval={5000}
        autoplayDelay={2000}
      />
      <Pagination
        dotsLength={size(banners)}
        activeDotIndex={banneActive}
        inactiveDotOpacity={0.6}
        inactiveDotScale={0.6}
        containerStyle={styles.dotsContainer}
        dotStyle={styles.dot}
        dotColor={styles.dot.backgroundColor}
        inactiveDotColor={styles.dot.backgroundColor}
      />
    </View>
  );
}

我注意到不再支持react-native-snap-carousel了，所以我迁移到了react-native-reanimated-carousel
