运行 Jest/Enzyme 在 React Native 上测试时出现 Babel 错误

Question

在一个巨大的包升级之后，当运行ning Jest 测试我们的应用程序时，我们有这个错误：

TypeError: [BABEL] /home/grubshka/devel/project/src/engine/models/Hive.ts: Cannot add property 1, object is not extensible
  at Array.push (<anonymous>)

  at node_modules/@babel/core/lib/config/full.js:314:26
  at Function.<anonymous> (node_modules/@babel/core/lib/gensync-utils/async.js:25:3)
  at evaluateSync (node_modules/gensync/index.js:251:28)
  at Function.sync (node_modules/gensync/index.js:89:14)
  at sync (node_modules/@babel/core/lib/gensync-utils/async.js:68:25)
  at sync (node_modules/gensync/index.js:182:19)
  at onFirstPause (node_modules/gensync/index.js:210:24)

错误的第一个路径非常随机，有时它来自 react-native 文件...

在本地计算机上，如果我们随机运行测试特定文件，在一些测试之后它开始工作，并且在这之后所有测试都工作，似乎某处有一些缓存... 在 CI 上，它永远不起作用。

这是我们的主要配置文件：

// babel.config.js

module.exports = {
  presets: [
    'module:metro-react-native-babel-preset',
    '@babel/preset-typescript',
    '@babel/preset-flow'
  ],
  plugins: [
    ['@babel/plugin-transform-flow-strip-types'],
    ['@babel/plugin-proposal-decorators', { legacy: true }],
    ['@babel/plugin-proposal-class-properties', { loose: true }]
  ],
  env: {
    production: {
      plugins: ['react-native-paper/babel']
    }
  }
}

// jest.config.js

const { defaults: tsjPreset } = require('ts-jest/presets')

module.exports = {
  ...tsjPreset,
  preset: 'react-native',
  globals: {
    'ts-jest': {
      tsconfig: 'tsconfig.jest.json',
      babelConfig: true
    }
  },

    ...tsjPreset.transform,

        ".eslintrc.js"

    ],
    "include": [
        "**/*.ts",
        "**/*.tsx",
        "**/*.js",
        "**/*.jsx"
    ]
}

如果需要，我可以提供更多配置文件。

谢谢！

更新 Jest 和 Babel（以及我们所有的模块）修复了错误...
