无法在 Laravel 8 中运行迁移：SQLSTATE[HY000] [2002] php_network_getaddresses：getaddrinfo 失败：名称或服务未知

Question

我不明白为什么我的迁移在 Laravel 8 的全新安装中失败。这就是我得到的：

 Illuminate\Database\QueryException 

  SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Name or service not known (SQL: select * from information_schema.tables where table_schema = bunny and table_name = migrations and table_type = 'BASE TABLE')

  at vendor/laravel/framework/src/Illuminate/Database/Connection.php:678
    674?         // If an exception occurs when attempting to run a query, we'll format the error
    675?         // message to include the bindings with SQL, which will make this exception a
    676?         // lot more helpful to the developer instead of just the database's errors.
    677?         catch (Exception $e) {
  ? 678?             throw new QueryException(
    679?                 $query, $this->prepareBindings($bindings), $e
    680?             );
    681?         }
    682? 

      +33 vendor frames 
  34  artisan:37
      Illuminate\Foundation\Console\Kernel::handle()

我真的尝试过寻找解决方案，但没有成功。我在完美的 Laravel 环境中使用 Kali linux，但版本 8 不起作用。

只是在 .env 文件中将 DB_HOST 的值更改为 127.0.0.1

“DB_HOST=mysql改为DB_HOST=127.0.0.1”
