我不知道为什么突然不工作了，但这是我的jest.config.js：

module.exports = {
  preset: 'react-native',
  verbose: true,
  moduleFileExtensions: ['ts', 'tsx', 'js', 'jsx', 'json', 'node'],
  setupFiles: ['./jestSetup.js'],
  transformIgnorePatterns: [
    'node_modules/(?!(jest-)?react-native|@react-native-community|@react-navigation)',
  ],
  moduleNameMapper: {
    '.+\\.(css|styl|less|sass|scss|png|jpg|ttf|woff|woff2)$': 'jest-transform-stub',
  },
};

我的jestSetup.js：

我已经看过了正确的文档，无法弄清楚这是如何突然失败的，下面是完整的错误消息：

node_modules/@react-native/polyfills/error-guard.js:14
    type ErrorHandler = (error: mixed, isFatal: boolean) => void;
         ^^^^^^^^^^^^

    SyntaxError: Unexpected identifier
