Doctrine表migrations_versions列长度

Question

在带有 Doctrine Migrations 2.2.0 的 Symfony 5 上，我想执行自定义的 Doctrine 迁移文件。我的实体是使用 InnoDB utf8mb4_unicode_ci （doctrine.yaml 中的默认值）创建的。

当我执行时bin/console doctrine:migrations:status --show-versions我得到：

An exception occurred while executing 'CREATE TABLE migration_versions (version VARCHAR(1024) NOT NULL, executed_at DATETIME NOT NULL COMMENT '(DC2Type:datetime_immutable)', PRIMARY KEY(version)) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci ENGINE = InnoDB':
SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 3072 bytes

所以我修改doctrine_migrations.yaml并将version_column_length的值更改为255，但现在使用相同的命令我得到

In BaseNode.php line 425:                                                                                                                                
Invalid configuration for path "doctrine_migrations.storage.table_storage.version_column_length": The minimum length for the version column is 1024.  
                                                                                                                                                        
In ExprBuilder.php line 187:
The minimum length for the version column is 1024.  

可以将自动创建的实体表的 varchar 长度更改为 1024，因此这不是我的数据库的限制。如何自动创建具有适当列长度的migrations_versions表？

我的同事通过简单地注释该行找到了解决方案 version_column_length: 1024
