Laravel Artisan 可以与 MySQL 对话，但 Laravel 网页不能？

【问题标题】：Laravel Artisan can talk to MySQL but Laravel web page cannot?Laravel Artisan 可以与 MySQL 对话，但 Laravel 网页不能？
【发布时间】：2020-04-25 09:45:31
【问题描述】：

我有一个运行 ubuntu(16.04)/apache(2.4)/php(7.2)/mysql(5.7) 的新 VM，并且我已经安装了 Laravel 5.5.latest。

我已经在 .env 文件中设置了数据库连接详细信息。 （这是正确的，因为我可以使用它们在命令行上连接 mysql）

Laravel artisan 可以与 DB 对话，因为我的迁移已经成功（我可以在命令行上看到来自 mysql 的表）

但是 Laravel 网页无法访问 db，抱怨表 db_name.table_name 不存在。

我在页面中进行了一些调试，它转储了正确的 .env db 设置。

知道为什么数据库在 CLI 上由 Artisan 工作，而不是通过网页工作吗？

【问题讨论】：

  • 显示堆栈跟踪
  • 在 Laravel 中执行此操作的命令？
  • 是的，并附在问题上
  • 已添加，但格式有点乱，抱歉
  • 您是否验证了property_types 表已在 artisan 命令中使用并且确实存在于 db 中？

【解决方案1】：

我们今天遇到了这个问题，解决方法是更改​​.env文件后重新启动php artisan serve。

如果还是不行，你也可以试试：

php artisan config:clear
php artisan config:cache
