Why does this error appear? "TypeError: mkdirp is not a function"

问题

以下是您提供的代码的翻译部分：

上述错误发生在我运行代码时，因此文件创建过程不起作用。请告诉我解决方案。

此代码用于基于Naver Trend API和Naver Advertising API计算结果，然后创建图形。它分为两个文件，服务器和插件，密钥在另一个文件中创建并发送。整个代码似乎没有问题，但似乎模块未正确安装或文件路径错误。我一直在寻找解决方案，但找不到。

// 代码部分已删除

我在本地服务器上运行了此代码，但在输出结果后未完成后续任务。

请注意，我已删除了代码中的敏感信息，如密钥等。如果您需要进一步的帮助或解决问题，您可以提出具体的问题或补充信息。

英文:

The above error occurred when I was running the code, so the process of creating the file is not working. Please let me know the solution.

This code is used to calculate the results based on the Naver Trend API and Naver Advertising API, and then create a graph. It is written in two files, server and addon, and the keys are created in another file and sent. The entire code seems to be fine, but it seems that the module is not installed properly or the file path is wrong. I've been looking for a solution, but I can't find it.

let server = app.listen(port, function () {

I ran this code on my local server, but the subsequent tasks were not completed after the output of the result.

得分: 1

查看文档：

// 混合模块，import 或 require() 都可以工作
import { mkdirp } from 'mkdirp'
// 或：
const { mkdirp } = require('mkdirp')

导出是一个对象。mkdirp 函数是该对象的属性。

您试图调用该对象本身，就好像它是一个函数一样。

英文:

Look at the documentation:

> // hybrid module, import or require() both work
> import { mkdirp } from 'mkdirp'
> // or:
> const { mkdirp } = require('mkdirp')

The export is an object. The mkdirp function is a property of that object.

You are trying to call the object itself as if it were a function.
