遠く離れたDBとローカルDBの間の移行を急いで行いますか？
オンラインD6ウェブサイトとローカルD8ウェブサイトの間で移行を設定しようとしています。だから私はこのようにD6 DBに接続したいと思います：
drush @vmdevd8ce migrate-upgrade --legacy-db-url=mysql://d6dbuser:d6dbpass@d6server/d6_distantdb --legacy-root=http://www.d6url.com --configure-only
drush @vmdevd8ce migrate-upgrade --legacy-db-url=mysql://d6dbuser:d6dbpass@d6serverdistantdb --legacy-db-prefix=dbpref_ --legacy-root=http://www.d6url.com --configure-only --debug
私の遠いDBにはプレフィックス名がありますが、プレフィックステーブル名はありません。しかし、私はPHPエラーを受け取ります：
PHP Fatal error: Call to undefined method Drush\Sql\SqlBase::dbSpecFromDbUrl() in /var/www/drupal-8/modules/contrib/migrate_upgrade/src/MigrateUpgradeDrushRunner.php on line 131
Drush command terminated abnormally due to an unrecoverable error. [error]
Error: Call to undefined method Drush\Sql\SqlBase::dbSpecFromDbUrl() in /var/www/drupal-8/modules/contrib/migrate_upgrade/src/MigrateUpgradeDrushRunner.php, line
131

ローカルのD6DBに接続しようとすると、機能します。それで、私のコマンドには何が欠けていますか？ドラッシュの制限ですか？
ありがとう
さて、問題はMigrate更新モジュール8.x-3.0-rc5から発生しているようです。8.x-3.0-rc4にロールバックして修正してください。接頭辞付きDBには接頭辞情報は必要ありません。
