Laravel 9 -不能声明类CreateUsersTable，因为名称已经在使用中

我删除了用户Laravel之后的迁移文件然后创造了一个新的。血已经干了，我干这行太久了。迁移文件中的类名是CreateUsersTable我把它改成了CreateUserTable．我删除了数据库，从一开始…我清除了Laravel的缓存，但是…文学真的什么都没有……它在哪里缓存?1-2小时前我删除了另一个迁移文件，但Laravel并不真正关心它的信息在哪里?

错误信息:

这是我的2022_06_21_124328_user.php":

<?php
use IlluminateDatabaseMigrationsMigration;
use IlluminateDatabaseSchemaBlueprint;
use IlluminateSupportFacadesSchema;
class CreateUserTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->id();
$table->string('username');
$table->string('name');
$table->string('email')->unique();
$table->timestamp('email_verified_at')->nullable();
$table->string('password');
$table->timestamp('account_verified')->nullable();
$table->integer('level')->default(0); // 0 - member, 1 - moder, 2 - admin
$table->string('bio')->nullable();
$table->string('avatar')->nullable();
$table->string('cover')->nullable();
$table->integer('audience')->default(0); // 0 - public, 1 - private
$table->timestamp('birth_date')->nullable();
$table->string('location')->nullable();
$table->string('website')->nullable();
$table->integer('disabled')->default(0);
$table->rememberToken();
$table->timestamps();
});
}
/**

*
* @return void
*/
public function down()
{
Schema::dropIfExists('users');
}
}

您可以使用anonymous migration，因为Laravel开始推荐它如下:

<?php

use IlluminateDatabaseMigrationsMigration;
use IlluminateDatabaseSchemaBlueprint;
use IlluminateSupportFacadesSchema;

return new class extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('flights', function (Blueprint $table) {
$table->id();
$table->string('name');
$table->string('airline');
$table->timestamps();
});
}

/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::drop('flights');
}
};

参考:https://laravel.com/docs/9.x/migrations migration-structure

希望我的解决方案能帮到你:使您的迁移名称与类名称相同。因此，如果您的类名为CreateUserTable，那么迁移名称应该与以下内容完全相同:

CreateUserTable => create_user_table.php
