Npm workspaces build with cache fails

Support

I have a build issue with a monorepo application that uses npm workspaces. The initial build succeeds but subsequent builds fail. If I clear cache and build again it succeeds. I’ve included the build log and my netlify.toml at the bottom.

As you can see, the build fails because of a missing dependency (rimraf).

Here’s my abbreviated root package.json:

{
    "private": true,
    "type": "module",
    "workspaces": ["./backend", "./common", "./frontend"],
    ...
}

And here is my abbreviated package.json from the frontend package which is what’s is failing to build:

{
    "private": true,
    "type": "module",
    "scripts": {
        "prebuild": "rimraf dist",
        "build": "parcel build src/index.html src/connector.html"
    },
    "devDependencies": {
        "rimraf": "^3.0.2",
        ...
    },
    ...
}

In the build log there’s No npm workspaces detected even though I’m using npm workspaces. Maybe that’s causing the issue but I have no idea how to get the build image to detect workspaces.

Hey @EmilEriksen,

Our docs show how to work with npm workspaces: Monorepos | Netlify Docs

One thing that stands out is, you’re using relative paths ./, maybe try without that?

Thank you @hrishikesh. That worked! Workspaces are now correctly detected (npm workspaces detected) and the build no longer fails :slight_smile:
