Laravel 迁移 - 创建时间戳时的问题

Laravel Migrations - Issues while creating timestamps(Laravel 迁移 - 创建时间戳时的问题)

问题描述

I am trying to run migrations on my Laravel instance. They are just the default migrations (users and password resets) but when it tries to make the timestamps it throws this error:

 [IlluminateDatabaseQueryException]
 SQLSTATE[42000]: Syntax error or access violation: 1067 Invalid default value for 'created_at' (SQL: create table `
 users` (`id` int unsigned not null auto_increment primary key, `name` varchar(255) not null, `email` varchar(255) n
 ot null, `password` varchar(60) not null, `remember_token` varchar(100) null, `created_at` timestamp default 0 not
 null, `updated_at` timestamp default 0 not null) default character set utf8 collate utf8_unicode_ci)

as well as a PDOException:

SQLSTATE[42000]: Syntax error or access violation: 1067 Invalid default value for 'created_at'

How can I fix this?

Thanks.

This is due to MySQL not accepting zero as a valid default date and thus the table creation fails a constraint check on creation.

You probably have NO_ZERO_DATE enabled in your MySQL configuration. Setting this to off will allow you to create the table or alternatively remove the default 0 value or change it to CURRENT_TIMESTAMP.

You can find out more about this exact issue here: https://github.com/laravel/framework/issues/3602
