Lesson 6: Error Creating mainnet-fork?

[hai-yr]

I am trying to add the development mainnet-fork using the following command:

hai-yr-MacBook-Pro smartcontract-lottery % brownie networks add development mainnet-fork -dev cmd=ganache-cli host=http://127.0.0.1 fork=https://eth-mainnet.alchemyapi.io/v2/ALCHEMY_PROJECT_ID accounts=10 mnemonic=brownie port=8545

the response I see on terminal:

Brownie v1.17.2 - Python development framework for Ethereum

Usage: brownie networks <command> [<arguments> ...] [options]

and when I check networks I see this:
─Ganache-CLI (Mainnet Fork) │ ├─id: mainnet-fork │ ├─cmd: ganache-cli │ ├─host: http://127.0.0.1 │ └─timeout: 120 │ ├─accounts: 10 │ ├─evm_version: istanbul │ ├─fork: mainnet │ ├─gas_limit: 12000000 │ ├─mnemonic: brownie │ └─port: 8545

But when I run networks --delete mainnet-fork -dev I get Usage: brownie networks <command> [<arguments> ...] [options] again... and can still see the "mainnet fork" shown above. Is this an error message? The cli is definitely not giving the success response that is shown in the tutorial.

I'm seeing a space in "mainnet-fork -dev" Were you intending to do "mainnet-fork-dev" (no space)? The command that worked for me was:
brownie networks add development mainnet-fork cmd=ganache-cli host=http://127.0.0.1 fork=https://eth-mainnet.alchemyapi.io/v2/[MYKEY] accounts=10 mnemonic=brownie port=8545

Yes @hai-yr have a space on "mainnet-fork -dev" so brownie is not recognizing it as a real command. You are awesome @NathanPtrs !!
