Netlify doesn't install dependencies, build script only works by manually adding `npm install`

codemacabre · August 8, 2022, 6:33pm

I’m running a fairly standard Eleventy site but for some reason it’s started failing to build on Netlify since I’ve started using the markdown-it and markdown-it-attrs packages. It builds fine locally.

They are listed in package.json:

"dependencies": {
  "markdown-it": "^13.0.1",
  "markdown-it-attrs": "^4.1.4",
  "sass": "^1.53.0"
}

But when running my build command, I get the error:

6:50:27 PM: [11ty] 1. Error in your Eleventy config file '/opt/build/repo/.eleventy.js'. You may need to run `npm install`. (via EleventyConfigError)
6:50:27 PM: [11ty] 2. Cannot find module 'markdown-it'

I’ve tried tweaking my eleventy.js config and my build script and the only thing that seems to work is by prepending my build command with npm install.

I thought Netlify automatically ran npm install so I’m unsure why I need to do this. Anyone have any insight?

My build settings:

Base directory: _site
Build command: npm run build
Publish directory: Not set
Builds: Active

My build script:

"build": "npx sass style:_site/style && npx @11ty/eleventy"

Bump, as I’ve tried pulling the build image and debugging on Docker (as detailed in [Support Guide] Debugging Netlify site builds) and still can’t figure this out.

Hi,

I got a similar issue, I got a hint by setting an environment variable in netlify UI
NPM_FLAGS to --verbose

It shows me that I was trying to install via our private repository, so I did update by updating my .npmrc.

Does your package.json and package-lock.json are at the root of your repo or in _site.
If it is at the root of your repo, you should consider using npm workspaces.

Hey there, @codemacabre

Thanks for reaching out! Can you share your site so that we can look into your specific case further?

codemacabre · August 11, 2022, 4:15pm

Thanks, @hillary. My site is https://codemacabre.com and the repo is at GitHub.

EDIT: I tried setting node version in the environment variables, as I noticed it was using 12.18.0 on Netlify. Now it uses 16.16.0 (the same as I’m using locally), but I’m getting the same issues.

I also tried creating a fresh package.json using npm init and added only the essential dependencies (@11ty/eleventy and sass). That built on Netlify, no problem. As soon as I added markdown-it, it failed again (on Netlify; local is fine), with the same issues as above.

hrishikesh · August 12, 2022, 3:05pm

The problem is due to your build cache: Netlify App as compared to Netlify App.

We save the SHA of your package.json in the build cache. If the SHA doesn’t change, we restore Node Modules from cache and skip installing them again. If the SHA doesn’t change, we simply restore the cache.

The problem in your case is that, somehow either your package.json’s SHA is not changing, or we’re not detecting it and thus, the “cached” version of Node Modules doesn’t contain the newly added dependencies.

Could you confirm that if you clear cache and deploy, it works every time?

codemacabre · August 12, 2022, 3:22pm

Hi @hrishikesh, unfortunately I’ve tried using the ‘clear cache and deploy’ option several times (and just tried again) but still get the same error when it attempts to access markdown-it.

codemacabre · August 12, 2022, 3:27pm

Well I’ve fixed it.

Based on what you suggested, @hrishikesh, that it was a cache issue, I just unlinked my entire repo, then re-linked it. That appears to have solved the problem. No idea why.
