Deploying ganache-local w/brownie: VM Exception while processing transaction: invalid opcode about brownie_fund_me HOT 12 CLOSED

Closing for now, if it's an issue with the M1... I won't be much help here sorry :/

from brownie_fund_me.

Thanks for the kind words!

This is likely due to the function you're calling... it doesn't like what you're doing. What happens when you use just the regular development network? Like brownie run scripts/deploy.py?

Or... did you install with pipx or pip?

from brownie_fund_me.

I am getting the same error after adding

`def withdraw():
fund_me = FundMe[-1]
account = get_account()
fund_me.withdraw({"from": account})

def main():
fund()
withdraw()`

@PatrickAlphaC I installed with pipx. This was initially in the discussion here if you want to see all of the things we have tried. One user got it working. A few others have this same issue

from brownie_fund_me.

There might be something wrong with your local network... what happens when you remove the network flag?

from brownie_fund_me.

If I import deploy_fund_me() and run it prior to running fund() & withdraw() to ganache-cli it works properly. If I don't do that it can't find an instance of FundMe[-1]. I believe that happens because ganache-cli isn't persistent.

from brownie_fund_me.

Right, that makes sense. I'm thinking it's something wrong with your local chain... what happens when you try it on a testnet?

from brownie_fund_me.

If I run deploy.py and then fund_and_withdraw.py (w/o redeploying the mocks) I get the same error:

I also have ~17.5 ETH in my Rinkeby test account.

from brownie_fund_me.

ValueError: Gas estimation failed: 'execution reverted: You need to spend more ETH!'

This means you're not sending enough ETH, and your entrance fee is off. How are you getting the entrance fee?

from brownie_fund_me.

I cloned your repo and added my .env file. Same code.

from brownie_fund_me.

Do you have ETH in your metamask?

from brownie_fund_me.

I have Rinkeby eth as well. I was able to get this to work on ganache-local when I reinstalled on old machine. This appears to be a conflict with my installation/environment. @cromewar suggested I uninstall my versions of Python and try to reinstall them.

I was excited getting a new MacBook Pro M1 Max Pro next week, but I've heard that there are some issues with web3 and the new silicon. :/

I do appreciate your help @PatrickAlphaC. If you can suggest how I might be able to diagnose - that would be great. If not, please feel free to close this ticket.
