Lesson 7: Brownie compile issue - Invalid version of this package

[AmiyoKC]

I'm trying to run brownie compile and am getting the error below. Been stuck with this for quite a few days. Am not sure what's going wrong. I read through other responses to a similar issue but wasn't quite able to fix this issue. It's not clear to me which package's version the error message below is talking about

PS C:\Users\amiyo\demos\smartcontract-lottery> brownie compile

Hello @AmiyoKC this a problem due to the python version you are using, python 3.10 have been reported as not 100% compatible yet with some of web3 dependencies, I strongly suggest you to use python 3.8, and also on a virtualenv ;)

@AmiyoKC can you use markdown in ur posts? makes reading the code a lot more readable. Use three ` before and after your code.

code goes here

I think the problem is with the chainlink version, you have 1.3.1 and the correct version is:

@cromewar I made this change and happy to note that I'm past this error :) I don't know how I missed that. Thanks a ton again for reviewing the errors and pointing this out.

I'm glad it worked, feel free to make any other question ;)
