npm run build error: Could not load unenv/dist/runtime/npm/whatwg-url.mjs/webidl2js-wrapper: ENOENT

Hi everyone, I've been struggling with a build issue for the past week when running the command npm run build. Despite my efforts, I haven't been able to resolve it. I’ve tried multiple solutions, including removing and reinstalling modules and updating to Nuxt 3.16.1, but nothing has worked so far. At this point, I'm exhausted from troubleshooting on my own, so I’d really appreciate any insights or suggestions. I've attached my dependencies for reference. Note: when I tried to build using "npm run generate" it generates the website without issues. Thank you in advance for your help!

Hi @Abdulrahman. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the knowledge sources provided, I can see that you're encountering a build error related to unenv when running npm run build with Nuxt 3.16.x. This appears to be a known issue with Nuxt 3.16.0 and related to the unenv dependency. Several similar errors have been reported in the GitHub issues, particularly after upgrading to Nuxt 3.16.0. Here are some potential solutions: 1. Add unenv as a dev dependency: One user reported that manually adding unenv as a dev dependency resolved the issue:

   npm add -D unenv

   npm add -D unenv

or if you're using pnpm:

   pnpm add -D unenv

   pnpm add -D unenv

2. Clean your project and reinstall dependencies: As mentioned in this GitHub issue, deleting certain folders and the lockfile before reinstalling can help:

   # Remove these directories and files
   rm -rf .nuxt .output node_modules package-lock.json
   # Then reinstall
   npm install

   # Remove these directories and files
   rm -rf .nuxt .output node_modules package-lock.json
   # Then reinstall
   npm install

3. Downgrade Nitro version: One user mentioned that using Nitro 2.10.4 instead of the latest version worked as a temporary fix. 4. Update to the latest patch version: Make sure you're on the very latest patch version of Nuxt 3.16.x, as some issues might have been fixed in patch releases. It's interesting that npm run generate works without issues. This suggests that the problem might be specific to the server-side rendering build process, which is more heavily used in the standard build compared to static site generation. The root cause appears to be related to changes in the unenv package, which handles environment compatibility in Nuxt. In Nuxt 3.16.0, there was a transition to using unenv v2, which has different implementations and requirements than the previous version. If none of these solutions work, you might want to consider temporarily downgrading to Nuxt 3.15.4, which several users reported as stable in the knowledge sources. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai i tried the first solution installing the unenv and it's same error, regrading the second solution "downgrading nitro" how to downgrade the nitro version?

kapa.ai•2w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on the knowledge sources, you can downgrade Nitro by adding an override in your package.json file. This approach was mentioned by a user in one of the GitHub issues who faced similar problems with Nuxt 3.16.0. Here's how you can downgrade Nitro to version 2.10.4:

"overrides": {
  "nitropack": "2.10.4",
  "h3": "1.15.0"
}

"overrides": {
  "nitropack": "2.10.4",
  "h3": "1.15.0"
}

Add this to your package.json file, then delete your node_modules folder and lockfile (package-lock.json, yarn.lock, or pnpm-lock.yaml depending on what package manager you use), and reinstall your dependencies. As mentioned in this GitHub issue, a user reported:

"I believe the issue is very related to whats discussed in the discord thread, related to Nitro, h3 and the oHash methods. Until a stable version is released my solution is to use this since I've already wasted an entire work day:
"nuxt": "3.13.2",
},
"overrides": {
  "nitropack": "2.10.4",
  "h3": "1.15.0"
}
"nuxt": "3.13.2",
},
"overrides": {
  "nitropack": "2.10.4",
  "h3": "1.15.0"
}
"

This approach forces your project to use the specified versions of these packages, which might help resolve the build error you're experiencing. After making these changes, try running npm run build again to see if the issue is resolved. If you're still experiencing issues, you might also want to try completely cleaning your project by removing the .nuxt and .output directories as mentioned in the second solution you referenced. Let me know if this helps! ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai unfortunately this is not worked for me. even downgrading the nuxt to 3.10 not worked with me also, same error

kapa.ai•2w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- I'm sorry to hear that downgrading Nitro and Nuxt didn't resolve your issue. Based on the knowledge sources, there are a few more specific issues and solutions we can try. Let's look at some of the more detailed problems that have been reported with similar error messages in Nuxt 3.16.0: 1. Complete cleanup and reinstall: Make sure you're doing a thorough cleanup before reinstalling:

   rm -rf .nuxt .output node_modules package-lock.json
   npm install

   rm -rf .nuxt .output node_modules package-lock.json
   npm install

2. Check Node.js version: Some users reported that specific Node.js versions helped resolve similar issues. According to this GitHub issue, one user mentioned:

"I picked Node v23.9, and it solved the problem for me."

3. Check for Cloudflare compatibility: If you're deploying to Cloudflare, you might need to add compatibility flags to your configuration:

   compatibility_flags = ["nodejs_compat"]

   compatibility_flags = ["nodejs_compat"]

4. Try overriding ohash: Another user in this GitHub issue mentioned:

   "overrides": {
     "ohash": "1.1.5"
   }

   "overrides": {
     "ohash": "1.1.5"
   }

5. Check for conflicting dependencies: Run npm why unenv or equivalent for your package manager to see if you have conflicting versions of unenv. The error you're experiencing seems to be related to the transition to unenv v2 in Nuxt 3.16.0, which has different implementations and requirements than the previous version. The fact that npm run generate works but npm run build doesn't suggests it might be related to the server-side rendering process. If none of these solutions work, you might want to consider creating a minimal reproduction of your issue and sharing it on the Nuxt GitHub repository, as the maintainers have requested reproductions for similar issues to help diagnose the root cause. Let me know if any of these additional approaches help with your build error. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
