[BUG] Auto-completion not work in pwsh

[dysuby]

Describe the bug

I try to install auto completion by running python main.py --install-completion pwsh and it executes successfully. But I only get path hint but not command hint.

To Reproduce

• Create a file main.py with:

import typer


def complete_name():
    return ["Camila", "Carlos", "Sebastian"]


def main(
    name: str = typer.Option(
        "World", help="The name to say hi to.", autocompletion=complete_name
    )
):
    typer.echo(f"Hello {name}")


if __name__ == "__main__":
    typer.run(main)

• Run python main.py --install-completion pwsh

Expected behavior

just help me complete commands

Screenshots

Environment

• OS: Windows10
• Typer Version: 0.3.2
• python version: 3.9.0

I have run the test case below:
https://github.com/tiangolo/typer/blob/c3a4c72a4f1a18b7f16addb508862ec63411fa63/tests/test_completion/test_completion_install.py#L140-L147

I am not sure this test case can work as we expected, because it write expected output into the profile and assert it is in the profile directly 😂

I think you must execute the script with typer after installing typer-cli, or install your project as a package, for autocomplete to work. That way it can customize the autocomplete for your command, rather than generic python .... See https://typer.tiangolo.com/typer-cli/
