出现Type Error

[SmartOinker]

当我输入 scrapy crawl HotSearchSpider 时，出现了 builtins.TypeError: expected string or bytes-like object

(VirtualEnv) D:\Documents\HCI\Sec 4\CSC\Research Paper\WeiboSpider-master\WeiboSpider>scrapy crawl HotSearchSpider

请问这问题怎么解决呢？谢谢。

请将setttings.py中第63行'WeiboSpider.middlewares.RetryMiddleware': 544,改为'WeiboSpider.middlewares.RetryMiddleware': None,，即禁用RetryMiddleware，这个中间件有点问题，最近太忙了没时间改，后续会陆续跟进，也可以直接提PR。
