为什么组件反应原生打字机不起作用?

标签: react-native

我按照了here指示,但它仍然不起作用。

我正在尝试这个外部组件:https://www.npmjs.com/package/react-native-typewriter

所以,我已经安装了它:

  

npm install --save react-native-typewriter

然后我写了这段代码:

index.android.js

'use strict';

import {AppRegistry} from 'react-native';
import TypingText from './app/textanimation.js';

AppRegistry.registerComponent('AwesomeProject', () => TypingText );

textanimation.js

import React, {Component} from 'react'
import TypeWriter from 'react-native-typewriter';

class TypingText extends Component {
  render() {
     return <TypeWriter typing={1}>Hello World!</TypeWriter>
  }
}

export default TypingText;

的package.json

{
  "name": "AwesomeProject",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "react": "15.4.2",
    "react-native": "0.41.2",
    "react-native-push-notification": "^2.2.1",
    "react-native-sound": "^0.9.0",
    "react-native-typewriter": "^0.3.0",
    "react-native-vector-icons": "^4.0.0"
  },
  "devDependencies": {
    "babel-jest": "18.0.0",
    "babel-preset-react-native": "1.9.1",
    "jest": "18.1.0",
    "react-test-renderer": "15.4.2"
  },
  "jest": {
    "preset": "react-native"
  },
  "rnpm": {
    "assets": [
      "assets/fonts/04b03"
    ]
  }
}

但我收到以下错误:

  

似乎你正试图从中获取'ReactNative.Component'   'react-native'包。也许你打算访问'React.Component'   而来自'react'包呢?

For example, instead of:

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

You should now do:

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

好的,我终于得到了react-native-typewriter包问题的解决方案。

导航到node_modules&gt;反应天然-打字机&GT; index.js 从

编辑以下标题
import React, {
  Component,
  Text,
  PropTypes,
} from 'react'

import React, {
  Component,
  PropTypes,
} from 'react'

import {
  Text,
} from 'react-native'

简短示例

import React,{Component} from 'react';
import{AppRegistry,} from 'react-native';
import TypeWriter from 'react-native-typewriter';
export default class HelloWorld extends Component{
    constructor(){
    super();
    }
    render() {
           return <TypeWriter typing={1}>Hello World!</TypeWriter>
        }
}
AppRegistry.registerComponent('HelloWorld', () => HelloWorld);
