brownie run is designed to be run without any extra arguments besides the ones listed in
brownie run -h.
All arguments are passed into the
docopt function which parses the options based on the docstring. Any extra arguments that are not listed causes the parser to throw the error you are seeing.
You can still use brownie to deploy your contract. But you will need to perform the brownie setup and argument parsing inside your python script. Then just call
python create_myToken.py with your arguments.
The main things to setup for brownie are connecting to a network and loading your project.
myproject = brownie.project.load('path/to/project')
Then you can either call your python project contracts on your
myproject object, or you could go the next step of importing everything, similar to having an active project in the directory. Just be aware that to import, you'll need to either use the resolved name of the project or pass a name in while loading the project.
from brownie.project.<ResolvedNameProject> import *
myproject = brownie.project.load('path/to/project', 'my_project')
from brownie.project.my_project import *
