换个cmd工具看看。

[zhanglu19970326]

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？ D:\weibo\weibo-search-master

修改过search.py吗？

[zhanglu19970326]

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'

猜测没有对齐，您增删下附近的空格试试。

[zhanglu19970326]

好的，我自己再摸索摸索，谢谢你~

[zhanglu19970326]

我直接重新下载了代码，很顺利爬出来了，谢谢你！
