Is there a possibility to install a conan package without requirements? I build a metapackage, which only contains some configurations and depends on other binary packages in the requires section.
Now I want to access only the configurations w/out downloading all dependencies, Is there a possibility to do so?
conan download downloads a package, but won’t install it, e.g. there is no info, where it’s downloaded, conan install offers the --json option for that. It’s not configurable with -s, too.

Yes, conan download command. It ignores settings.

Not really, it’s installed as equal in conan data folder. To obtain any package path, you can run conan info --paths (see info), but info command will download package dependencies.
You have few options:
- Run
conan downloadand copy what you need:
conan download spdlog/1.8.5@:ff8d59d47be9cd9bef245bc941640efed49089de -r conan-center
cp ${HOME}/.conan/data/spdlog/1.8.5/_/_/package/ff8d59d47be9cd9bef245bc941640efed49089de/licenses/LICENSE new_folder/LICENSE
SpdLog requires fmt package, but we don’t want to download it too. Thus, we can’t run conan install --paths
- Run
conan install -g deployand copy what you need.
conan install spdlog/1.8.5@ -r conan-center -g deploy cp spdlog/licenses/LICENSE new_folder/LICENSE
The deploy generator will download all dependencies, but they will be copied to the current folder too.
Also, partial download was requested some time ago: https://github.com/conan-io/conan/issues/6508, but was denied.
