Laravel 5 时间戳更改字段上的迁移错误
在laravel 5.7/mysql 5应用程序中,我想将默认值设置为timestamp字段(创建时未设置): 但我有一个错误:Laravel 5 时间戳更改字段上的迁移错误,laravel-5,migration,Laravel 5,Migration,在laravel 5.7/mysql 5应用程序中,我想将默认值设置为timestamp字段(创建时未设置): 但我有一个错误: Unknown column type "timestamp" requested.

通常情况下,我对时间戳字段没有任何问题,我认为method->change引起了这个问题。
如何修复它
修改块#1:
我已经把它填好了
my composer.json:

],

}
}
通过谷歌搜索,我发现我还需要安装marktopper/dbal时间戳类型
我安装了它,运行迁移时并没有错误,但并没有定义默认时间戳处的created_,所以添加的新行在created_中为null
$ php artisan --version
Laravel Framework 5.7.21
$ node -v
v10.15.0
$ npm -v
6.5.0
谢谢 无法更改/修改时区列类型的状态
只能“更改”以下列类型:bigInteger、binary、boolean、date、dateTime、dateTimeTz、decimal、integer、json、longText、mediumText、smallInteger、string、text、time、unsignedBigInteger、unsignedInteger和unsignedSmallInteger
最好使用原始sql查询更新列,如下所示:
DB::statement('ALTER TABLE `table_name` CHANGE `column_name` `column_name` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP;');
您是否添加了依赖性原则?在使用change()时需要安装此选项;作曲家要求条令/D请查看修改的块#1
DB::statement('ALTER TABLE `table_name` CHANGE `column_name` `column_name` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP;');
