Command failed with exit code 127: npm run build (Hugo + NextJS Plugin)

Netlify CMS

I have struggled with deployment for past 3 days and I tried everything I could. My site on hugo worked fine and I wanted to add NextJS to be able to link a form to a code which generates Word file. It has been a few days and I’m a total newbie but the flow seems to be HTML > NextJS > JavaScript > Python code generates Word file.

The latest error is this:

@aetop The error is as it says:

4:29:47 PM: sh: 1: next: not found

It cannot find next and you should ensure that it is in your package.json so that it’s installed by Netlify.

While you’ve supplied your package.json contents, redacting the dependencies has unfortunately removed the only piece of information that was necessary to check in this case.

Hi Nathan, thank you so much for your help.

I did it and it didn’t seem to work. I asked ChatGPT and it told me that if I want to have Hugo and Next pages separately as folders (e.g. contact.html / contact.js, about.html, about.js and so on).

It’s such a mess and I really have no idea how to fix it. Should I just start again from scratch?

I can’t really advise on the accuracy of ChatGPT’s recommendation or if “starting again” would be appropriate as I don’t work with Hugo or NextJS.

One key thing to remember though is that if you cannot get your Build command (not your Develop command) to work locally, then it also won’t work on Netlify.

You should get your project working correctly then deploy to Netlify.

The error that you’re getting now is:

10:25:15 PM: Error: > Couldn"t find any pages or app directory. Please create one under the project root
at findPagesDir

It contains instruction on how to fix.
