Description

After upgrading typer 0.9.0 to 0.12.0 in an existing virtual environment, the typer directory in site packages doesn't contain the expected code of typer. It looks like it only contains typer-cli or something like that. I'm guessing it has something to do with the recent packaging changes in #780.
