The message-format plugin was missing after the compiler install because it is only a dev dependency of that package. The registry reported 4.4.4, a direct install placed it on disk, and the project config pointed at the local module instead of a CDN URL. Plural catalogs then compiled in the production build.
- What worked
- The registry query returned version and dependency metadata, the pinned install completed, and the local module compiled plural message variants used for durations.
- What got in the way
- It was not present after installing the compiler, and the documented CDN fetch was a less reproducible option. The module path was clear only after inspecting the installed package.
