Getting an error when working with Brownie

Question

When I want to run the reputation .sol file and use brownie compile, I get the following error (using a PowerShell window).

cd C:\Users\s\Documents\project\reputationproject
brownie compile

Output:

How can I fix it?

Answer 1

• Have you checked the Solidity compiler version?
• install pip3 install solc-select
• solc-select install <version mentioned in the Solidity files>
• solc-select use <the same version>
