An error occurred while installing mysql2 (0.5.5), and Bundler cannot continue.

In Gemfile:
  mysql2

Someone can help me or give an advice?

This happened to me too after brew updated mysql to 8.3. Seems like Percona Tools have the same issue:
https://perconadev.atlassian.net/jira/software/c/projects/PT/issues

As a workaround for now i downgraded MySQL to 8.0:

brew uninstall mysql
brew install mysql@8.0

Afterwards mysql2 installed without issues.

This looks like a duplicate of #1346
