我在我自己的功能组件中使用react-native-paper。我想为我的组件编写 Jest 测试。

问题：当我将组件导入 Jest 测试文件时，我收到此错误：

TypeError: Cannot assign to read only property 'name' of function 'function () {for (var _len2 = arguments.length, args = new Array(_len2), _key2 = 0; _key2 < _len2; _key2++) {ar...<omitted>... }'
at node_modules/react-native-paper/src/core/withTheme.js:136:46
   at Array.forEach (<anonymous>)
at withTheme (node_modules/react-native-paper/src/core/withTheme.js:124:5)
at Object.<anonymous> (node_modules/react-native-paper/src/components/Typography/Text.js:46:24)
at Object.<anonymous> (node_modules/react-native-paper/src/components/BottomNavigation.js:16:48)`

试图缩小错误范围，我发现即使是这个简单的 Jest 文件也会导致错误。
