Question

说明

我在运行项目时遇到了一个非常模糊的错误（之前有效），我猜这点与项目无关。

在昨天大部分时间都在努力解决这个问题之后，我意识到本土的反应已经自我更新了。

我尝试过的事情：

使用各种工具清理项目后，我摆脱了另一个错误，导致项目在构建过程中失败（react-native run-ios）。

yarn upgrade
yarn cache clean
react-native upgrade
rm -rf ios/build/; kill $(lsof -t -i:8081); react-native run-ios

但是，我仍然遇到同样的问题

babel github上提到的问题似乎也在谈论类似的问题：

问题

为什么我得到一个模糊的错误，说我有一个未处理的js异常？

要解决这个问题，我必须将我的react和react-native依赖项升级到最新版本，这解决了这个问题。

{
  "name": "FluxRN",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "moment": "^2.22.0",
    "native-base": "^2.5.2",
    "react": "^16.3.1",
    "react-native": "0.55.4",
    "react-native-vector-icons": "^4.6.0",
    "react-navigation": "^1.5.9"
  },
  "devDependencies": {
    "babel-jest": "23.0.1",
    "babel-preset-react-native": "4.0.0",
    "jest": "23.1.0",
    "react-test-renderer": "^16.3.1"
  },
  "jest": {
    "preset": "react-native"
  }
}

未处理的JS异常：意外的标识符＆＃39; _Object $ defineProperty＆＃39;。导入只需要一个参数
