刮擦：属性错误：模块'OpenSSL.SSL'

Question

我正在Window 10 OS上的pipenv虚拟环境中运行Scrapy。

我的代码：

# QuoteSpider.py
import scrapy

class QuoteSpider(scrapy.Spider):
name = 'quotes'
start_urls = [
'http://quotes.toscrape.com/'
]
def parse(self, response):
title = response.css('title').get()
yield {'titletext': title}

运行Scrapy后，我收到以下错误：

我已经阅读了与这个问题有关的其他一些答复；它们都不起作用。这就是我再次询问的原因。我也尝试过以下方法，但没有成功：

1. 卸载和安装pyopenssl
2. 升级pyopenssl

pip install pyOpenSSL~=22.1.0

3. 升级requests

pip install pyOpenSSL~=2.28.1

感谢的帮助

Answer 1

遇到了同样的问题。我降级到pyOpenSSL==22.0.0，现在我又开始工作了。我怀疑这是一个兼容性问题，scratch会赶上。

Answer 2

我也尝试了上述步骤，但没有成功，最终修复了它：其中一个错误指向Scrapys"tls.py"；。在那里你可以找到以下代码：

openssl_methods = {
METHOD_TLS: SSL.SSLv23_METHOD,                      # protocol negotiation (recommended)
# METHOD_SSLv3: SSL.SSLv3_METHOD,                     # SSL 3 (NOT recommended)
METHOD_TLSv10: SSL.TLSv1_METHOD,                    # TLS 1.0 only
METHOD_TLSv11: getattr(SSL, 'TLSv1_1_METHOD', 5),   # TLS 1.1 only
METHOD_TLSv12: getattr(SSL, 'TLSv1_2_METHOD', 6),   # TLS 1.2 only
}

我评论了包含"；"METHOD_SLv3"；现在又开始工作了。

我知道已经太晚了，但你应该升级你的旧版本。查看此处的发布文档：https://docs.scrapy.org/en/2.6/news.html.上面说他们已经更新了
