React native 不能开玩笑；反应自然工作

试图让Jest v12.1.1与React Native v0.26.2一起使用时，我在运行npm测试时遇到此错误：

错误：无法从“env.js”中找到模块“ErrorUtils”

这是我的

package.json

。我正在尝试使用默认的

react native init AwesomeProject

starter来实现这一点

我的package.json中是否缺少某些内容？（这里有我不需要的线路吗？）

示例1:

package.json

{
  "name": "AwesomeProject",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start"
  },
  "dependencies": {
    "react": "^15.0.2",
    "react-native": "^0.26.2"
  },
  "devDependencies": {
    "babel-jest": "^9.0.0",
    "babel-preset-es2015": "*",
    "babel-preset-react": "*",
    "jest-cli": "^12.1.1"
  },
  "scripts": {
    "test": "jest"
  },
  "jest": {   
    "scriptPreprocessor": "node_modules/react-native/jestSupport/preprocessor.js",
    "setupEnvScriptFile": "node_modules/react-native/jestSupport/env.js",        
    "testPathIgnorePatterns": [
      "/node_modules/",
      "/android/",
      "/ios/",
      "/.idea/"
    ],    
    "testFileExtensions": [
      "js"
    ],
    "unmockedModulePathPatterns": [
      "<rootDir>/node_modules/react/",
      "<rootDir>/node_modules/react-dom/",
      "<rootDir>/node_modules/react-addons-test-utils/"
    ],    
    "verbose": true
  }
}

{
  "name": "AwesomeProject",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start"
  },
  "dependencies": {
    "react": "^15.0.2",
    "react-native": "^0.26.2"
  },
  "devDependencies": {
    "babel-jest": "^9.0.0",
    "babel-preset-es2015": "*",
    "babel-preset-react": "*",
    "jest-cli": "^12.1.1"
  },
  "scripts": {
    "test": "jest"
  },
  "jest": {   
    "haste": {
      "defaultPlatform": "android",
      "platforms": [
        "ios",
        "android"
      ],
      "providesModuleNodeModules": [
        "react-native"
      ]
    },    
    "testPathIgnorePatterns": [
      "/node_modules/",
      "/android/",
      "/ios/",
      "/.idea/"
    ],    
    "testFileExtensions": [
      "js"
    ],
    "unmockedModulePathPatterns": [
      "<rootDir>/node_modules/react/",
      "<rootDir>/node_modules/react-dom/",
      "<rootDir>/node_modules/react-addons-test-utils/"
    ],    
    "verbose": true
  }
}

示例2:

当我将“haste”添加到

package.json

并删除

scriptPreprocessor

&

setupEnvScriptFile

时，会出现另一个错误。

错误：无法从“index.android test.js”中找到模块“AwesomeProject”

我不知道为什么我会在以下方面走得更远。我前面的示例1如下所示： 带有“haste”的示例2如下所示：

真的很困惑为什么Ex 1不起作用

在react native GitHub上发现Jest和RN v0.26存在类似问题：使用Jest@11.x.x对你有用吗？您使用的是示例1还是示例2（您已经列出）方法？
