    该错误是因为您的本机项目版本反应 .

    你现在必须通过这个版本创建这样的项目--->

    react-native init ProjectName --version 0.55.4

    只需等待React Native的下一个版本让他们解决这个问题 .

    如果你的find发现像本机版本0.56那样，请参阅package.json文件的依赖关系和devDependencies ---->

    "react-native":"0.56.0"

    在依赖项中然后将其更改为

    "react-native":"0.55.4"

    并在devDependencies中更改

    "babel-preset-react-native": "5",

    至

    "babel-preset-react-native": "4.0.0",

    最后跑

    npm install

    似乎降级react-native版本将解决问题 . 你使用的是最新的0.56.1吗？新版本非常不稳定，尤其是在运行Windows时 .

    降级到0.55.4应该可以解决您的问题： npm install react-native@0.55.4

    你可以看看这个非常类似的问题：https://github.com/facebook/react-native/issues/14209

    我假设您使用的是Windows . 我最近得到了同样的错误，当我在github上搜索本地的反应问题时，看到人们改变了他们的 package.json 文件 . 对我的案例有用的是，你可以根据自己的需要进行调整;

    {
  "name": "AwesomeProject",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "react": "16.3.1",
    "react-native": "0.55.4"
  },
  "devDependencies": {
    "babel-jest": "22.4.4",
    "babel-preset-react-native": "4.0.0",
    "jest": "22.4.4",
    "react-test-renderer": "16.3.1"
  },
  "jest": {
    "preset": "react-native"
  }
}

    不要忘记先删除你的 node_modules 文件夹，然后改变你的 package.json ，类似于上面，然后最后运行 npm install .
