我正在从Typescript文件导入函数：
第一个月
myExportedFunction函数调用同一文件中的非导出函数：

const myNonExportedFunction = () => {
    ... code ...
}

export const myExportedFunction = () => {
    myNonExportedFunction();

    ... more code ...
}

字符串
当我运行它时，我得到：Uncaught Reference error: 'myNonExportedFunction' is not defined。如果我用myNonExportedFunction内部的代码替换函数调用，一切都正常。
为什么我得到这个错误？上下文：这段代码是一个Chrome插件。
tsconfig：
