已配置ES模块相关设置仍无法加载，寻求技术解决方案

Hey there, let's work through this pesky error—you've already updated Node.js and set type="module" in your package.json, so let's dig into the edge cases that often cause this issue to stick around:

• Double-check your package.json details
  First, make sure your package.json lives in your project's root folder (not a subdirectory) and the type field is spelled perfectly—no typos like types instead of type. It should look exactly like this:

  {
    "type": "module"
  }
  

  JSON is super strict, so even a missing comma or mismatched quote elsewhere in the file can make Node ignore the type setting entirely.

• Ditch the --experimental-modules flag
  That flag was only needed for early ES module support back in Node.js 13 and earlier. Starting from Node.js 14.13.0, ES modules are fully stable—using this flag now can actually cause conflicts with modern Node versions. Just run node index.js directly instead.

• Confirm your updated Node.js version is active
  It's easy to update Node but still have an old version running in your terminal (especially if you use tools like nvm or nvs). Run node -v to check your active version—if it's not the latest stable release, switch to the updated one before running your script.

• Check for conflicting file extensions or subfolder configs

  • If you have files with .cjs extensions, those are treated as CommonJS modules by default. If you're trying to import an ES module into a .cjs file, you'll hit this error. Either convert that .cjs file to use ES module syntax (and rename it to .js) or use dynamic import() instead of static import statements.
  • Make sure no subfolders in your project have their own package.json with a conflicting type field (like "type": "commonjs")—that would override the root setting for all files in that subfolder.

• Ensure your module syntax is consistent
  In a type="module" project, you can't use require() or module.exports—you have to stick with ES module syntax: import and export. If any file in your project (or even a dependency) is mixing these incorrectly, it can trigger this error. Double-check all your imports and exports across every file.

• Reset Node's module cache
  Sometimes Node hangs onto old module settings in its cache. Try deleting any node_modules/.cache folder if you have one, restart your terminal, and run your script again.

If none of these fix it, create a minimal test project to isolate the issue: make a new folder, add a simple package.json with "type": "module", create an index.js that imports a tiny utility file (like import './utils.js' where utils.js has a basic export), and run node index.js. If that works, the problem is likely in your main project's dependencies or hidden configuration quirks.
