[英]I want to run the php artisan migrate command but I get an error
我有一個項目,我想遷移數據庫文件,但是當我嘗試運行 PHP artisan migrate 命令時出現錯誤
我搜索了很多,但我沒有得到任何有用的結果,請幫助我
這是我的數據庫文件代碼:
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateBlogTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('blogs', function (Blueprint $table) {
$table->id();
$table->integer('user_id');
$table->string('name');
$table->string('text');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('blogs');
}
}
這是一條錯誤消息

與錯誤狀態一樣,該表已經存在。
當您第一次運行遷移時,在創建表后遇到錯誤時,可能會發生這種情況。
解決此問題的最簡單方法是登錄數據庫並手動刪除表,然后再次運行遷移。
您可以運行“php artisan migrate:fresh”現有表將被自動刪除並重新生成表
我認為您的錯誤的解決方案是“學習 laravel”。
