Failed to compile contracts with TypeError: Function needs to specify overridden contract "GovernorVotes"

[wuminqi]

Failed to run npm run compile on OSX 12.6 with Node.js v16.4.2.

The message says TypeError: Function needs to specify overridden contract "GovernorVotes".

It appears that override(Governor, IGovernor) should be override(GovernorVotes, IGovernor) to pass the compilation according to the message tip.
