Lesson 4: File is not a zip file

[AmiyoKC]

When I run python deploy.py in the terminal window, I get the following error message. Any ideas how to get past this?
I've been through most of the discussion items but haven't been able to solve this.

this comes from the first line of the code (from solcx import compile_standard, install_solc)

PS C:\Users\amiyo\demos\web3_py_simple_storage> python deploy.py
Cannot find solc, installing...
Downloading solc v0.8.11 from https://github.com/ethereum/solidity/releases/download/v0.8.11/solidity-windows.zip

Hello @AmiyoKC this is a rare error on python but also well known, this means your zip file which contains Solcx is corrupted (may be due to a network failure) the solution is complicated actually, you should do a rfind of the package and then add \x00\x00 on this line zipFileContainer.write('\x00\x00') which is a pain to do.

My suggestion is you to reinstall python, and also choose version 3.8 is the most stable for brownie development.

Hi @cromewar - thanks so much! I re-installed Python as you suggested and now it works perfectly! I however, just installed the latest python - 3.10 so I hope I don't run into issues later when I get to Brownie.
