What is your suggestion?

conan download (version>2.x) shows an import error message when downloading a conan 1.x recipe.

The error message should be omitted or clarified because it seems that the command has failed, although the recipe has been downloaded.

Current output:

conan download --only-recipe tinydir/1.2.4 -r conancenter
Downloading recipe 'tinydir/1.2.4#cc72af24237f34698122f8b87eea32e9'
ERROR: Error loading conanfile at '/Users/anonymous/.conan2/p/tinyddab41e98996fb/e/conanfile.py': Unable to load conanfile in /Users/anonymous/.conan2/p/tinyddab41e98996fb/e/conanfile.py

ImportError: cannot import name 'ConanFile' from 'conans' (/Users/anonymous/venv/lib/python3.9/site-packages/conans/__init__.py)

Suggested output.

Show that conan has downloaded the recipe successfully but it seems that it is not compatible with the installed conan client.
