I was trying to deploy my Hugo blog to Neltify and deploy failed with the following error:

11:38:08 AM: Command failed with exit code 255: hugo --gc --minify
I spent about 48 hours to resolve this error and even created a PR for the Hugo theme I use. The repo’s maintainer helped me.
Hugo cannot find Bulma, because Bulma is submodule.
To resolve this issue we need:
Step 1: I have added the following lines to netlify.toml in Hugo project:
[build]
publish = "public"
command = "git submodule update --force --recursive --init --remote && hugo --gc --minify"
Step 2: I changed the Build command in Build settings on Netlify. I set it to:
hugo --gc --minify --buildFuture
The fix was appearing immediately on Netlify:
