victory-native可以和expo一起使用吗?

Can victory-native be used with expo?

我正在玩 Victory Native chart library in an app where I'm using Expo。然而,我遇到了一些胜利组件导致应用程序崩溃的问题,例如<VictoryChart> 这对于使用该库非常重要。有谁知道是否可以使用 victory-nativewith Expo?

我了解到 Expo 不允许使用 Victory Native 可能使用的原生元素?

这是我所做的:

  1. exp init expo-victory-native-demo
  2. cd expo-victory-native-demo(来自here
  3. npm install --save victory-native react-native-svg
  4. npm install
  5. react-native link react-native-svg

然后我试玩了找到的演示 here,即将一些 Victory 组件放入 App.js,但是当我 运行 exp start 之后应用程序立即崩溃例如 <VictoryChart> 存在时启动,如果我只使用 <VictoryBar>.

则不是问题

有一个将 Victory Native 与 Expo 结合使用的演示(请参阅 here),但我需要将其与现有的大型项目一起使用 Expo 并尝试在此演示之外使用 Victory Native 失败,如前所述多于。这也使用旧版本的 Expo 和 Victory Native。

为了完整起见,这是我的 App.js 崩溃了:

import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
import { VictoryBar, VictoryChart, VictoryTheme } from "victory-native";

const data = [
  { quarter: 1, earnings: 13000 },
  { quarter: 2, earnings: 16500 },
  { quarter: 3, earnings: 14250 },
  { quarter: 4, earnings: 19000 }
];

export default class App extends React.Component {
  render() {
    return (
      <View style={styles.container}>
        <VictoryChart width={350} theme={VictoryTheme.material}>
          <VictoryBar data={data} x="quarter" y="earnings" />
        </VictoryChart>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#fff',
    alignItems: 'center',
    justifyContent: 'center',
  },
});

移除 <VictoryChart> 后它不会崩溃:

import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
import { VictoryBar, VictoryChart, VictoryTheme } from "victory-native";

const data = [
  { quarter: 1, earnings: 13000 },
  { quarter: 2, earnings: 16500 },
  { quarter: 3, earnings: 14250 },
  { quarter: 4, earnings: 19000 }
];

export default class App extends React.Component {
  render() {
    return (
      <View style={styles.container}>
        <VictoryBar data={data} x="quarter" y="earnings" />
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#fff',
    alignItems: 'center',
    justifyContent: 'center',
  },
});

这里是 package.json:

{
  "main": "node_modules/expo/AppEntry.js",
  "private": true,
  "dependencies": {
    "expo": "^25.0.0",
    "react": "16.2.0",
    "react-native": "https://github.com/expo/react-native/archive/sdk-25.0.0.tar.gz",
    "react-native-svg": "^6.3.1",
    "victory-native": "^0.17.2"
  }
}

这个问题可能与 VictoryChart does not work with EXPO 23.0.0 有关。

通过执行以下操作解决了问题:

  1. rm -rf node_modules/
  2. package.json 中删除 react-native-svg(参见 here
  3. npm install --save lodash
  4. yarn install

然后在 exp start 之后我得到了以下信息:

App.js 看起来是这样的:

import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
import { VictoryBar, VictoryChart, VictoryTheme } from "victory-native";

const data = [
  { quarter: 1, earnings: 13000 },
  { quarter: 2, earnings: 16500 },
  { quarter: 3, earnings: 14250 },
  { quarter: 4, earnings: 19000 }
];

export default class App extends React.Component {
  render() {
    return (
      <View style={styles.container}>
        <VictoryChart width={350} theme={VictoryTheme.material}>
          <VictoryBar data={data} x="quarter" y="earnings" />
        </VictoryChart>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#fff',
    alignItems: 'center',
    justifyContent: 'center',
  },
});

package.json

  "main": "node_modules/expo/AppEntry.js",
