我尝试使用scrapy-playwright从动态加载的javascript网站中提取一些数据，但我停留在一开始。
从我在www.example.com文件中遇到的麻烦settings.py如下：

剧作家

DOWNLOAD_HANDLERS = {
        "http": "scrapy_playwright.handler.ScrapyPlaywrightDownloadHandler",
        "https": "scrapy_playwright.handler.ScrapyPlaywrightDownloadHandler",
    }

#TWISTED_REACTOR = 'twisted.internet.asyncioreactor.AsyncioSelectorReactor'
#ASYNCIO_EVENT_LOOP = 'uvloop.Loop'

当我注入下面的杂剧作家汉德勒：

DOWNLOAD_HANDLERS = {
    "http": "scrapy_playwright.handler.ScrapyPlaywrightDownloadHandler",
    "https": "scrapy_playwright.handler.ScrapyPlaywrightDownloadHandler",
}

然后我得到：

scrapy.exceptions.NotSupported: Unsupported URL scheme 'https': The installed reactor 
(twisted.internet.selectreactor.SelectReactor) does not match the requested one (twisted.internet.asyncioreactor.AsyncioSelectorReactor)

当我注入TWISTED_REACTOR时”

TWISTED_REACTOR = 'twisted.internet.asyncioreactor.AsyncioSelectorReactor'

然后我得到：

raise TypeError(
TypeError: SelectorEventLoop required, instead got: <ProactorEventLoop running=False closed=False debug=False>

毕竟，当我注入ASYNCIO_EVENT_LOOP时
然后我得到：

ModuleNotFoundError: No module named 'uvloop'

最后，无法安装“uvloop”

pip install uvloop
