C:/../react-native/jest/mockComponent.js: Unexpected token (20:23)

  Jest encountered an unexpected token
  This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.
  By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".
  Here's what you can do:
   • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
   • If you need a custom transformation specify a "transform" option in your config.
   • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.
  You'll find more details and examples of these config options in the docs:
  https://jestjs.io/docs/en/configuration.html

这对我有用

我认为问题在于为我安装了jest和jest expo，这很有效：

"transformIgnorePatterns": [
    "/node_modules/(?!sentry|react-native).+\\.js$",
],

请注意，您必须在此处列出所有节点模块

静态显示名称='组件'

我也有同样的问题，在react native应用程序中运行纱线测试App-test.js时，我也面临同样的问题。你有什么解决办法吗@Christis对我不起作用我还是会犯这个错误
