Issue Brownie setup, not sure if ganache installed properly - chainlink hackathon

Question

I am new to this space and having an issue getting brownie to run my first deploy script. I am learning through the Chainlink Hackathon and following the brownie tutorial by Patrick Collins. I think the problem is with ganache. Any help would be appreciated.

When I ask for the version of ganache - it says not found (see below). when I try to install via npm, I receive error no 13. Is this related to Mac OS?

Error message when trying to deploy script:

brownie run scripts/deploy.py

This is the deploy script provided by chainlink hackathon. Error message in visual studio code that highlights brownie ("Import "brownie" could not be resolved pylance...")

from brownie import SimpleStorage, accounts

def main():
    account = accounts[0]
    simple_storage_contract = SimpleStorage.deploy({"from": account})
    print(simple_storage_contract.number())

Answer 1

The error isn't actually to do with Ganache (the fact that Ganache gets stuck there is supposed to happen; that means it is running at that IP address and port).

What is happening is you have a syntax error in your deploy.py file at line 8. It is saying you have simple.storage when what you want is simple_storage (with the underscore instead of the period). Make sure you fix line 8 in the script and save the file.

Answer 2

Write terminal

sudo strong textnpm install -g ganache-cli
