您好！换了cmder运行，运行结果还是和之前一样（如下），是要再尝试别的运行工具吗？

SyntaxError: invalid syntax
没有修改，我看现在的代码已经把search.py中的parse_by_hour修改成 这个了： def parse_by_hour(self, response): """以小时为单位筛选""" keyword = response.meta.get('keyword') is_empty = response.xpath( '//div[@class="card card-no-result s-pt20b40"]') if is_empty: print('当前页面搜索结果为空') else: # 解析当前页面 for weibo in self.parse_weibo(response): self.check_environment() yield weibo next_url = response.xpath( '//a[@class="next"]/@href').extract_first() if next_url: next_url = self.base_url + next_url yield scrapy.Request(url=next_url, callback=self.parse_page, meta={'keyword': keyword})
我看到search.py157行的报错是这样的（如下），我看不太懂 Statement expected,found Py:COLON Statement expected,found Py:ELSE_KEYWORD Unexpected indent Expected type 'str',got 'object'instead start_date =datetime.strptime(start_date_str,%Y-%m-%d-%H) start date str:object date +'-0'
