ReferenceError: 初始化前无法访问 {variable name}

如何解决ReferenceError: 初始化前无法访问 {variable name}

我将 react-scripts@^4.0.3 和 typescript@~3.7.2 更新到最新，但是当我运行 npm run start 时，我收到以下错误：

ReferenceError: 初始化前无法访问{variable name}

我知道“临时死区”，但是这个应用程序在为这样的箭头函数声明导出时没有问题，事实上，我们用这种语法声明了大部分/所有函数：

export const someFunc = () => {}

现在只允许我像这样声明后导出：

function someFunction(){} -or- const someFunction = () => {}

export { someFunction }

问题：如何通过这些新的包更新允许导出速记函数表达式语法？
