我有一个使用 React Ui-Material 管理模板构建的 React 项目。它与 webpack 和一些附加功能捆绑在一起，但由于某种原因，在尝试映射数组时使用箭头函数时会引发错误。我在项目的其他模型中使用箭头函数，它工作正常。似乎只是在尝试在我的组件中进行映射时。
我已经尝试在我的 webpack 配置文件中查看事物的顺序，研究并尝试了其他人在我的 babelrc 和 eslintrc 文件中找到修复它的添加，但是在这一点上，我可以用一双新的眼睛，什么都没有已经奏效了。
这是我的文件。我会发布我能做的一切，只是为了彻底。
控制台错误：
./src/containers/CrimeWatch.js 中的错误模块构建失败：SyntaxError: Unexpected token, expected : (79:90)
我的组件抛出错误：

export default CrimeWatch;
地图部分中的箭头TableBody是引发错误的原因。
