Getting the following error when compiling.....

CompilerError: solc returned the following errors:

Do not forget to set up your brownie-config.yaml and set the oppenzepelin replacement for the solc compiler, something like this:

dependencies:
  - OpenZeppelin/openzeppelin-contracts@3.4.0
compiler:
  solc:
    remappings:
      - '@openzeppelin=OpenZeppelin/openzeppelin-contracts@3.4.0'

If no thing works you can always install the npm module for openzeppelin using:

npm install @openzeppelin/contracts

Thankyou @cromewar . I had done that, but your message prompted me to double check...found a spelling error.

@toddabraham so was that the issue?

[toddabraham]

@PatrickAlphaC see the screen shot, under remappings, I had misspelled @openzeppelin.
