Windows 下使用 phpunit 执行的时候一直提示报错，麻烦指点一二

这是我的代码

namespace Tests\Feature;
use Illuminate\Foundation\Testing\RefreshDatabase;
use Illuminate\Foundation\Testing\WithFaker;
use Tests\TestCase;
class TbTokenTest extends TestCase
{
    public function testExample()
    {
        $data = '{"my_account":"ihouxin"}';
        $response = $this->json('POST', '/hs/save_friend_message', ['data'=>$data]);
        $response->dumpHeaders();
        $response->dump();
        $response->assertJson(['code'=>200]);
    }
}

我使用的windows下的"phpunit.phar"工具。
在cmd命令行里面运行“phpunit”的情况下，提示报错
下面是错误截图

There was 1 error:

1) Tests\Feature\ExampleTest::testBasicTest
ErrorException: Declaration of Illuminate\Foundation\Testing\Assert::assertArraySubset($subset, $array, bool $checkForObjectIdentity = false, string $message = ''): void should be compatible with PHPUnit\Framework\Assert::assertArraySubset($subset, $array, $strict = false, $message = '')

ERRORS!

头部和内容是可以正常打印的 。就是最后会这样报错 ，是不是哪里配置错了？
