Nuxt Generate Failing in Deployment

I am attempting to deploy a nuxt site and have deployed it at least twice before. However, after updating a few items builds are failing in netfliy but succeeding locally.

Last thing changed in the repo, outside some html, was the addition of sass, sass-loader@10, and fibers. After reverting these changes the site deploys fine.

Local version of Node is 15.0.1 and npm is 7.0.3.


Changed the build version of Node to match local and it is deploying correctly.

So you fixed it?
What was the problem?

I had a similar issue with Nuxt. I just had to update both node and npm to the latest and it worked.

Hi @wildbeard

Thanks for coming back with an update on how you solved this for yourself. This information may assist others in the future.

It ended up being a node version mismatch.

I could dig into it further but I think it is either sass or sass-loader on node v16. I tried uninstalling fibers and it didn’t work so went ahead and rolled back the addition of sass and sass-loader and it deployed. Added all three back and set NODE_VERSION to 15.0.1 and it deployed successfully.
