javascript - 开发服务器返回响应错误码：500 react native

问题描述

我只是想react-native app.在 ubuntu 上使用 android 运行一个。现在，在这里我使用了react-native init. 在这里，我刚刚创建了一个项目，并尝试使用命令

react-native run-android

在此之后，我在模拟器上遇到错误，

所以，我不理解这个错误。

我的package.json

{
  "name": "AwesomeProject",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest",
    "android": "react-native run-android"
  },
  "dependencies": {
    "react": "16.6.1",
    "react-native": "0.55.4"
  },
  "devDependencies": {
    "babel-jest": "23.6.0",
    "jest": "23.6.0",
    "metro-react-native-babel-preset": "0.50.0",
    "react-test-renderer": "16.6.1"
  },
  "jest": {
    "preset": "react-native"
  }
}

我的.bablerc

{
  "presets": ["module:metro-react-native-babel-preset"]
}

有人可以帮我解决这个问题吗？
