对于您的场景，现在不推荐使用旧 WebView 以获得更好的性能并减少包大小。您可以在此处找到有关此的更多信息

解决方案

使用此命令安装新的 WebView 包

npm install --save react-native-webview 

您可以从此处找到有关软件包安装的更多信息

安装上述软件包后，现在删除旧的导入并像这样重新导入 WebView

import { WebView, } from 'react-native'; //Remove this from your imports

import { WebView } from 'react-native-webview'; //Add this to your imports

您的最终代码应如下所示：

import React, { Component } from 'react';
import { Text, Button, View, ScrollView } from "react-native";
import Chart from "react-native-f2chart";
import { WebView } from 'react-native-webview';  // New changed import
import { Container, Title } from "../components";
import { basePie, labelPie } from "./scripts";

type Props = {}; class PieChartScreen extends PureComponent {

render() {

return (

  <ScrollView>

    <Container>

      <View>

        <Title title="基础饼图" />

        <View style={{ height: 250 }}>

          <Chart initScript={basePie} webView={WebView} />

        </View>
      </View>

      <View>
        <Title title="带文本饼图" />
          <Chart initScript={labelPie} webView={WebView} />

        </View>

      </View>

      <View style={{ height: 20 }} />

    </Container>

  </ScrollView>

);
}

}

export default PieChartScreen;
