【问题描述】：

我已经尝试了很多我在谷歌搜索这个问题时看到的东西，但没有任何东西对我有用。

我正在运行带有 MAMP 的 Mac OS 10.13.4。此命令适用于我的带有 XAMPP 的 Windows 机器。

我尝试过的事情：

将 `.env` 中的 `127.0.0.1` 更改为 `localhost`
更改：`.env` 中的 `DB_PORT` 从 `3306` 到 `8889`
添加：`'unix_socket' => '/tmp/mysql.sock'`，到`config\database.php`

这是在终端输入php artisan migrate -v 时返回的内容。

SQLSTATE[HY000] [2002] No such file or directory (SQL: select * from information_schema.tables where table_schema = b_rowland and table_name = migrations)

  at /Users/blazerowland/Documents/Sites/Personal/Portfolio/vendor/laravel/framework/src/Illuminate/Database/Connection.php: 664
  660:         // If an exception occurs when attempting to run a query, we'll format the error
  661:         // message to include the bindings with SQL, which will make this exception a
  662:         // lot more helpful to the developer instead of just the database's errors.
  663:         catch (Exception $e) {
  664:             throw new QueryException(
  665:                 $query, $this->prepareBindings($bindings), $e
  666:             );
  667:         }
  668: 
  669:         return $result;

【问题讨论】：

使用MAMP的网页在.env中显示的配置。希望它会起作用。

标签： php laravel macos mamp

【解决方案1】：

在您的 .env 文件中，关于您的数据库配置，您是否填写了所有设置？

这是环境变量：

DB_CONNECTION=
DB_HOST=
DB_PORT=
DB_DATABASE=
DB_USERNAME=
DB_PASSWORD=

另外，如果你使用 mysql sock，你需要 DB_SOCKET=/mysql.sock

【讨论】：

【解决方案2】：

尝试使用改变环境。

 php artisan migrate --env=dev

【讨论】：

【解决方案3】：

尝试在您的终端中执行此操作：

 php artisan migrate --env=dev

【讨论】：

【解决方案4】：

我使用 XAMPP 在 MacOS 上工作，必须将其添加到 .env 文件中： DB_SOCKET=/Applications/XAMPP/xamppfiles/var/mysql/mysql.sock

【讨论】：

【解决方案5】：

愚蠢的答案，但仍然是一个答案。
跨 MAMP 和 Laravel .env 将我的服务器端口从 3306 更改为 4444。
对我来说很奇怪，我尝试过的所有其他端口都不起作用。希望这对其他人有帮助。

【解决方案6】：

这对你应该没问题！

转到位于项目中 app 文件夹的 Providers 目录中的 AppServiceProvider.php 文件。例如C:\xampp\htdocs\projectName\app\providers\AppServiceProvider.php。

然后输入以下内容：

use Illuminate\Support\Facades\Schema;

同样在同一个文件中，将引导函数编辑成这种格式。

public function boot()
{
    `Schema::defaultStringLength(255);
}

【讨论】：

您能否添加一些解释，为什么您的答案可以解决 OP 的问题？

【解决方案7】：

遇到类似问题，我无法执行 artisan 命令，并且 composer Update 和 dump-autoload 命令返回错误“Script @php artisan package:discover --ansi handling the post-autoload-dump event返回错误代码 255 "

在我的情况下，问题既不是作曲家也不是工匠命令，而是在处理 Exceptions/Handler.php 文件时由于 } 放错位置而导致的错误。我建议检查对默认 Laravel 文件的任何最近修改。希望这可以帮助某人。编码愉快。
