I'm doing the second step from the quickstart of the repo. But this is my output.

How can I fix it?

EDIT 1:

There was an error raised when I ran brownie run ./scripts/1_deploy_token.py, and I have figured it out the reason why it raised the exception.

The OurToken.sol' solidity version was inconsistent with ERC20.sol of [email protected] solidity version. refer the details below

The OurToken.sol solidity version specify

While ERC20.sol of [email protected] solidity version was

They were consistent. So when you ran the command as above. There is no suitable version of solidity for compile those files.

am getting this error when i run my deploy script
