从'ReactFiberTreeReflection.js'找不到模块'react/lib/ReactCurrentOwner'

我试图在这个jest tutorial的react-native中开始单元测试。但是当我运行npm test我得到的错误Cannot find module 'react/lib/ReactCurrentOwner' from 'ReactFiberTreeReflection.js'从'ReactFiberTreeReflection.js'找不到模块'react/lib/ReactCurrentOwner'

我的分量是最简单越好

// /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> 
     ); 
    } 
}

这里是我的测试文件

// /__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(); 
});

全部测试输出

    ● Test suite failed to run

我假设你已经运行'npm install'，对吧？如果有，请尝试删除'node_modules'文件夹并重新运行'npm install'。 –

已经做了几次，结果相同 –

尝试在GitHub上引用[this issue]（https://github.com/dalcib/jest-expo-ts/issues/1）。可以有一些有用的信息。 –

解决我自己的问题。

我没有创建项目，我在中间得到项目，所以我安装了新版本的react-native 0.45，与我的项目一样，我发现package.json devDependencies中的笑话版本不匹配。

这里是我的项目devDependencies

"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", 
},

这里新鲜的devDependencies安装

"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" 
},

似乎该项目已更新。

之后，我安装一切再次rm -rf node_modules && yarn install

再次运行npm test测试通过预期。
