ERR_REQUIRE_ESM Problem

[ghost]

This happened to me when i'm using mem in Typescript. Can anybody resolve this issue:

internal/modules/cjs/loader.js:1102
      throw new ERR_REQUIRE_ESM(filename, parentPath, packageJsonPath);
      ^

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: C:\Users\Tyo\Desktop\eemoji\node_modules\mem\dist\index.js
require() of ES modules is not supported.
require() of C:\Users\Tyo\Desktop\eemoji\node_modules\mem\dist\index.js from C:\Users\Tyo\Desktop\eemoji\dist\utils\Client.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from C:\Users\Tyo\Desktop\eemoji\node_modules\mem\package.json.

thank you for your response.

Unfortunately, I can't use the package in React Native. There's no ESM support out of the box.

There's nothing else to add here and the module will stay ESM-only. The previous version of mem can still be used as a CJS module like before.
