pyspider在python3.7中使用async关键字，到底如何解决？？？

Question

在python3.7中，pyspider使用了关键字async,到底该怎么解决？？？
不希望降级python版本。我把pyspider包中的async全部改为了async_，但是还是报错，具体如下：

Answer 1

async大写
CurlasyncHTTPClient → CurlAsyncHTTPClient

from tornado.curl_httpclient import CurlAsyncHTTPClient

Answer 2

批量替换注意勾选 全字符匹配words 和 大小写匹配 match case.你这是替换了多余的async导致的.
