brownie compile
Brownie v1.17.2 - Python development framework for Ethereum

New compatible solc version available: 0.6.0
Compiling contracts...
  Solc version: 0.6.0

CompilerError: solc returned the following errors:

I tried the solution from https://githubhelp.com/PatrickAlphaC/brownie_fund_me/issues/3
and changed my solc remappings from version 1.1.1
"@chainlink=smartcontractkit/[email protected]"
to version 0.2.2
"@chainlink=smartcontractkit/[email protected]"
and compiled again

but it throws this error

Any help would be appreciated

Hello @InsidTrifl
That's weird as the AggregatorV2V3Interface.sol does exists on the 0.2.2 version as you can see here

My recommendation on this case is:

1. use the latest version which is 0.4.0.
2. Delete your .brownie folder located in: /home/insidtrifl/.brownie
3. Restart all your terminals (preferably your computer) before proceed.

Does this help you?

I did what you said and it still was causing problems so...
I deleted the whole fund_me folder and restarted again and it compiled on the 1.1.1 version
thanks for your help
