Laravel：请求的列类型 "timestamp" 未知

Question

我正在尝试执行迁移，但遇到了以下问题。

Unknown column type "timestamp" requested. Any Doctrine type that you use has to be registered with \Doctrine\DBAL\Types\Type::addType(). You can get a list of all the known types with \Doctrine\DBAL\Types\Type::getTypesMap(). If this error occurs during database introspection then you might have forgotten to register all database types for a Doctrine Type. Use AbstractPlatform#registerDoctrineTypeMapping() or have your custom types implement Type#getMappedDatabaseTypes(). If the type name is empty you might have a problem with the cache or forgot some mapping information.

我的代码如下：

Schema::table('XXXXXXXX', function (Blueprint $table) {
        $table->timestamp('start')->change();
        $table->timestamp('end')->change();
    });

奇怪的是我已经用那种类型的数据执行了迁移：

Schema::create('XXXXXX', function (Blueprint $table) {
        ...
        $table->timestamp('date_expired')->nullable();
        ...

    });

有谁知道如何修复它或看到我正在做的错误。

谢谢

更新

In the end I have deleted the migration, I have modified it putting timestamp in the necessary columns and I have executed it again. (Having deleted the table before from the database)

在 laravel 文档页面上，您可以找到一条警告，告诉您某些类型不能与 ->change() 方法一起使用。

Link to laravel docs

它还说：

To modify a timestamp column type a Doctrine type must be registered.
