${path.relative('.', input)} does not exist

Error message

${path.relative('.', input)} does not exist

What it means

`do_build` validates the resolved input directory (from normalize_options) with `fs.existsSync` before scanning/packaging. If the input directory is missing, it throws an error showing the input path relative to the current directory.

Solutions

1. Create the expected directory or fix the path: ensure `src/lib` exists (default input).
2. Pass the correct input explicitly: `svelte-package -i <dir>`.
3. Run the command from the package root so relative input paths resolve correctly.
4. Remove a stale `svelte` field in package.json if it points to a non-existent directory.

Example fix

// before (package.json)
"svelte": "./src/Lib/index.js"

// after
"svelte": "./src/lib/index.js"

import fs from 'node:fs';
if (!fs.existsSync('src/lib')) throw new Error('src/lib missing: set -i to your source dir');

try {
  await run(['svelte-package']);
} catch (e) {
  if (String(e.message).endsWith('does not exist')) {
    throw new Error('Check the svelte-package -i input path and your cwd');
  }
  throw e;
}

When it happens

Trigger: Running `svelte-package` (or `build`/`watch`) when the configured `input` directory (default `src/lib`, or `-i`/package.json `svelte` field value) does not exist on disk.

Common situations: Wrong cwd when invoking the CLI; typo'd `-i` path; renamed source folder (e.g. `src` instead of `src/lib`); config in package.json pointing at an old layout.
