reactjs - React Native 升级到 0.56 版本后崩溃。可能是 Babel 问题？

Question

使用 react-native-git-upgrade 升级我的 React Native 项目后，出现以下错误:

error: bundling failed: TypeError: Cannot read property 'bindings' of null
    at Scope.moveBindingTo (/Users/jan/Startup/react-native/ordersome/node_modules/@babel/traverse/lib/scope/index.js:978:13)

这个问题好像和babel有关系。我重新启动了地铁和模拟器，但这并没有改变什么。这里还有我安装的所有与 babel (package.json) 有关的软件包:

"babel-eslint": "^8.2.5",
"babel-jest": "23.2.0",
"babel-preset-react-native": "4.0.0",

这是我的 .babelrc:

{
  "presets": ["react-native"]
}

当项目还处于 0.55 时，我使用 react-native init 生成了该项目。

尝试更新 package.json 中 babel-preset-react-native 的版本，如下所示:

“babel-preset-react-native”:“^5”。
