從'ReactFiberTreeReflection.js'找不到模塊'react/lib/ReactCurrentOwner'

我試圖在這個jest tutorial的react-native中開始單元測試。但是當我運行npm test我得到的錯誤Cannot find module 'react/lib/ReactCurrentOwner' from 'ReactFiberTreeReflection.js'從'ReactFiberTreeReflection.js'找不到模塊'react/lib/ReactCurrentOwner'

我的分量是最簡單越好

// /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> 
     ); 
    } 
}

這裏是我的測試文件

// /__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(); 
});

全部測試輸出

我假設你已經運行'npm install'，對吧？如果有，請嘗試刪除'node_modules'文件夾並重新運行'npm install'。 –

已經做了幾次，結果相同 –

嘗試在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。 –

解決我自己的問題。

我沒有創建項目，我在中間得到項目，所以我安裝了新版本的react-native 0.45，與我的項目一樣，我發現package.json devDependencies中的笑話版本不匹配。

這裏是我的項目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", 
},

這裏新鮮的devDependencies安裝

"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" 
},

似乎該項目已更新。

之後，我安裝一切再次rm -rf node_modules && yarn install

再次運行npm test測試通過預期。
