无法从'ReactFiberTreeReflection.js'中找到模块'react / lib / ReactCurrentOwner'

Question

我尝试在本地jest tutorial的反应原生中开始单元测试。但是当我运行npm test时，我收到错误Cannot find module 'react/lib/ReactCurrentOwner' from 'ReactFiberTreeReflection.js'

我的组件尽可能简单

// /SimpleComp.js
import React, { Component } from 'react';
import {
    View,
} from 'react-native';

export default class SimpleComp extends Component {
    constructor(props){
        super(props);
        this.state = {}
    }

    render() {
        return (
            <View></View>
        );
    }
}

这是我的测试文件

// /__tests__/SimpleComp-test.js
import 'react-native';
import React from 'react';
import SimpleComp from '../SimpleComp';

// Note: test renderer must be required after react-native.
import renderer from 'react-test-renderer';

test('renders correctly', () => {
    const tree = renderer.create(
        <SimpleComp />
    ).toJSON();
    expect(tree).toMatchSnapshot();
});

完整测试输出

解决我自己的问题。

我没有创建项目，我把项目放在中间，所以我安装了一个新版本的react-native 0.45，我的项目正在使用，我发现{{1}中的开玩笑版本是不匹配的。

以下是我的项目package.json devDependencies

devDependencies

这里是全新安装的"devDependencies": { "react-test-renderer": "16.0.0-alpha.6", "babel-preset-react-native": "1.9.1", "babel-jest": "19.0.0", "jest": "19.0.2", },

devDependencies

似乎项目已更新。

之后我再次安装所有内容"devDependencies": { "react-test-renderer": "16.0.0-alpha.12", "babel-preset-react-native": "4.0.0", "babel-jest": "21.0.2", "jest": "21.1.0" },

按预期再次运行rm -rf node_modules && yarn install测试通道。
