      Webpacker::VersionChecker - #{check_failed}

      You are currently not checking for consistent versions of shakapacker gem and npm package. A version mismatch or usage of semantic versioning wildcard (~ or ^) without a lockfile has been detected.

      Version mismatch can lead to incorrect behavior and bugs. You should ensure that both the gem and npm package dependencies are locked to the same version.

      You can enable the version check by setting `ensure_consistent_versioning: true` in your `webpacker.yml` file.

      Checking for gem and npm package versions mismatch or wildcard will be enabled by default in the next major version of shakapacker.
