Hi @baby4bamboo
You cannot request specific package-id in conanfile. You specify the recipe reference, down to the recipe revision, but not including the package_id part.
The binary that needs to be downloaded is computed as a function of the input settings, options (profile), and dependencies versions.
But in conan doc ,it says we can add package_id in conanfile :https://docs.conan.io/en/latest/versioning/revisions.html You can specify the references in the following formats: lib/1.0@conan/stable#RREV:PACKAGE_ID#PREV
Yes, this is not well explained in the docs, it doesn't mean that it can be used in the conanfile.txt or conanfile.py, but it might be used in other contexts (maybe search, remove, etc).
This should be better explained in the docs, transferring this issue to the docs repo, to clarify it in the docs.
