Click: No such option
Question:
I am trying to alter an existing framework having 18 flags to have 2 more flags. Every single time I try to use the flag, it says that the flag is not existing.

That is the given code. I tried to "realtime" and "interval".

Error: no such option: --interval
However, if I run the –help command, the commands are actually listed.
Is there anything I am doing wrong?
Answers:
click groups with subcommands are picky about argument ordering. Since what you’re attempting to modify is indeed a Click group, you’ll need to pass --interval before the subcommand name.
A simplified example:
import click
import dataclasses
@dataclasses.dataclass
class Config:
interval: int = 0
pass_config = click.make_pass_decorator(Config, ensure=True)
@click.group()
@click.option('--interval', default=1)
@pass_config
def cli(config, interval):
config.interval = interval
@cli.command()
@click.option('--toughness', default=8)
@pass_config
def mangle(config, toughness):
print(f"Mangling at {config.interval} interval and {toughness} toughness")
if __name__ == '__main__':
cli()
Passing --interval after mangle: no go.
$ python3 so73649041.py mangle --interval=8
Usage: so73649041.py mangle [OPTIONS]
Try 'so73649041.py mangle --help' for help.
Error: No such option: --interval
Passing --interval before mangle: go.
$ python3 so73649041.py --interval=3 mangle
Mangling at 3 interval and 8 toughness
Passing a subcommand’s option before its name: no go.
$ python3 so73649041.py --toughness=7 mangle
Usage: so73649041.py [OPTIONS] COMMAND [ARGS]...
Try 'so73649041.py --help' for help.
Error: No such option: --toughness
Passing everything: go.
$ python3 so73649041.py --interval=42 mangle --toughness=110
Mangling at 42 interval and 110 toughness
