Deploying to netlify fails with error: [vite]: Rollup failed to resolve import..., but it works when I build locally using npm run build (same as netlify). The package that fails to resolve is installed directly from github, as opposed to the other packages.

package.json:

    "dependencies": {
        "@tailwindcss/line-clamp": "^0.2.2",
        "focus-visible": "^5.2.0",
        "just-throttle": "^4.0.1",
        "lrud": "github:bbc/lrud#master",
        "sapper-environment": "^1.0.1"
    }

netlify logs:

10:10:52 PM: This is most likely unintended because it can break your application at runtime.
10:10:52 PM: If you do want to externalize this module explicitly add it to
10:10:52 PM: `build.rollupOptions.external`

keyNavigation.ts:

import { Lrud } from 'Lrud';

Why does deployment fail at netlify, but not locally?

The LRUD documentation says

const { Lrud } = require('Lrud')

and the following works locally:

import { Lrud } from 'Lrud';

That is probably because the Mac environment doesn't care about upper/lower case in file references in this context. However, on Netlify it makes a difference. Changing the import statement to the following made the Netlify deployment pass:

import { Lrud } from 'lrud';
