使用命令时，Laravel Lightning\Database\QueryException（无此类文件或目录）"；“php artisan迁移”；

我已经在VPS上安装了Laravel。我通过SSH与计算机连接

“php artisan migrate”命令返回以下错误：

   Illuminate\Database\QueryException

还要检查许多其他事项：

如果mysql容器已使用正确的数据集启动。sql脚本（在卷映射下）为空。因为如果不保存脚本，VSCode会将其保留为空


您还可以使用：docker compose exc container name登录容器，以检查init数据库文件是否存在


然后，尝试建立到mysql的连接，例如使用命令行：mysql-u username-D database-p。检查数据是否存在。如果上面的查询返回任何内容，请尝试该查询


在修复了所有这些之后。要检查的另一件事是.env文件中的变量DB_HOST。我的看法是：



DB_HOST=localhost
DB_HOST=127.0.0.1

然后改为：


DB_HOST=DB#DB是mysql映像的容器名

最后但并非最不重要的一点是，以下docker compose命令非常有用（app是您的容器名称或app名称）：

docker compose exec应用程序编写器安装
docker compose exec应用程序php artisan密钥：生成
docker compose exec应用程序php artisan配置：清除
