TypeError while running deploy.py script in brownie

Question

I initialized a new brownie project via the terminal by

$ brownie init

I wrote the following script in python:

def simple_print():
    print("Hello World!")

def main():
    simple_print()

saved it as deploy.py in the srcipts folder and then ran the following command in the terminal:

$ brownie run scripts/deploy.py

and got the following error:

INFO: Could not find files for the given pattern(s).
Brownie v1.18.1 - Python development framework for Ethereum

BrownieSimpleStorageProject is the active project.

Been at this for 4 days now, cannot find a solution. Please advise.

Answer 1

Check that the port numbers are the same between GUI and CLI. I was able to fix by going into Ganache (GUI) settings -> server and reset the port to 8545. Save and restart. Brownie should attach next time you run your deploy script.
