nodejs'文件类型'和'mime'：不支持ES模块的require()；将 index.js 更改为 CommonJS 模块中可用的动态 import()

Question

import mime from 'mime';
// import { mime } from 'mime'; // this is also tried

const determineFileType = async (filePath) => {
  const type = mime.getType(filePath);
  if (type) {
    logger.info(`File type is: ${type.mime} and the extension is: ${type.ext}`);
  } else {
    logger.info(`Could not determine the file type for ${filePath}`);
  }
  return type;
};

给出了这个错误：

我也尝试过这段代码：

import { fileTypeFromFile } from 'file-type';

...
const type = await fileTypeFromFile(filePath);
...

这给出了这个错误：

这里真的很困惑。

这个错误是什么？我找不到线索......

Answer 1

尝试使用 mime 版本 2.5.2。反而。我在使用 mime 4.0.4 时遇到了同样的错误，之后错误就消失了。
