kedro --version isn't working

[ankatiyar]

Description

Reported by @noklam, since adding lazy loading of Kedro subcommands, the --version/-V option isn't working.

Context

This bug is originating in Kedro 0.19.7 -> #3883

[noklam]

Usage: kedro [OPTIONS] COMMAND [ARGS]...
Try 'kedro -h' for help.

Error: No such option: -v

This is the stack trace when run kedro -V, kedro -v or kedro --version

[noklam]

While investgating this issue, I think it's worth checking why CI didn't catch this error, we have this test inplace.

    def test_print_version(self):
        """Check that `kedro --version` and `kedro -V` outputs contain
        the current package version."""
        result = CliRunner().invoke(cli, ["--version"])

        assert result.exit_code == 0
        assert version in result.output

how to reproduce the error? the command works well for me

[noklam]

@DimedS kedro -V,r kedro --version as mentioned. Are you using the main branch? Can you copy the terminal log when you do kedro?

I confirm kedro -V and kedro --version both give No such option errors with 0.19.9

I figured out what the problem is:

kedro/kedro/framework/cli/cli.py

Line 220 in a1fae50

return [*load_entry_points("global"), cli, global_commands]

Due to the changes in lazy loading PR, I re-ordered the global commands list to consider

• first the commands loaded from plugins,
• then cli which is the group with info and the version_option decorator
• and then the global_commands group which contains the new and starter lazy commands.

So if any plugin with global commands (eg. Kedro-Viz) is installed in your env, the --version option doesn't work. It works when you uninstall Kedro viz. Which is why it must be working in the CI and for @DimedS

The solution is simply to re-order the command groups to [cli, *load_entry_points("global"), global_commands] but that would mean that users can't overwrite kedro info which I think is acceptable.
