Lesson 6: Brownie compiling error

[markreni]

Hi,

I'm having some problems when compiling FundMe.sol. I'm getting this kind of error message in my terminal:

File "brownie/_cli/main.py", line 64, in main

AttributeError: 'dict' object has no attribute 'decode'

Would anybody have any idea what is wrong with compiling?

Thank you in advance,

on withdraw function funderIndex++ you have missing a ;, also please don't use anaconda for web3 development it's not full compatible yet, use plain python with pip instead, or WSL. additionally don't forget to install ganache-cli, as It seem is not running.
