Nuxt v5 / Nitro v3: unresolved imports for `nitropack/runtime` during build

[tobiasdiez]

Environment

• Package: @nuxtjs/robots 5.7.1
• Nuxt: https://pkg.pr.new/nuxt@95e6b9f
• Nitro: 3.0.260415-beta
• Vite: 7.3.1

Reproduction

Run pnpm build in a Nuxt v5 / Nitro v3 project using this package.

Actual result

The build emits UNRESOLVED_IMPORT warnings because the published runtime imports nitropack/runtime, which does not resolve in this setup.

[UNRESOLVED_IMPORT] Warning: Could not resolve 'nitropack/runtime' in node_modules/.pnpm/@nuxtjs+robots@5.7.1.../node_modules/@nuxtjs/robots/dist/runtime/server/plugins/initContext.js

import { defineNitroPlugin, getRouteRules } from "nitropack/runtime";

Affected files

• dist/runtime/server/plugins/initContext.js
• dist/runtime/server/routes/robots-txt.js
• dist/runtime/server/util.js
• dist/runtime/server/composables/useRuntimeConfigNuxtRobots.js
• dist/runtime/server/composables/getPathRobotConfig.js
• dist/runtime/server/composables/getBotDetection.js
• dist/runtime/server/kit.js

Expected result

No unresolved import warnings when building with Nuxt v5 / Nitro v3.
