Apcu在webman里边的Cache怎么使用??

return [
    'default' => 'apcu',
    'stores' => [
        'file' => [
            'driver' => 'file',
            'path' => runtime_path('cache')
        ],
        'redis' => [
            'driver' => 'redis',
            'connection' => 'default'
        ],
        'array' => [
            'driver' => 'array'
        ],
        'apcu' => [
            'driver' => 'apcu'
        ]
    ]
];

InvalidArgumentException: cache.store.apcu.driver=apcu is not supported. in /www/wwwroot/webman-pay/vendor/webman/cache/src/support/Cache.php:96

Cache::set();Cache::get(); 正常调用
