      This lockfile specifies a lockfile_version of #{version} which is
      lower than the minimum supported version #{MINIMUM_SUPPORTED_VERSION}.
      Please create a new lockfile for this project by running:
          inspec vendor
    EOF
  elsif version > CURRENT_LOCKFILE_VERSION
    raise <<~EOF
      This lockfile claims to be version #{version} which is greater than
      the most recent lockfile version(#{CURRENT_LOCKFILE_VERSION}).
      This may happen if you are using an older version of inspec than was
      used to create the lockfile.
