Answer 1

参考GPT和自己的思路：

你好，根据你提供的信息，该问题是由于OpenSSL模块内部的一个错误导致的。具体来说，NoReturn类在该模块的_typing.py文件中被导入，但无法被正确识别。为了解决这个问题，你可以尝试升级Anaconda和OpenSSL，并确保你的Python版本与你的OpenSSL版本兼容。或者，你可以尝试手动卸载并重新安装OpenSSL模块，或者使用Python虚拟环境来避免类似的问题。另外，你还可以在Anaconda的命令行环境中尝试安装Scrapy的依赖包来解决这个问题，比如 pip install Twisted pyOpenSSL。希望这个回答对你有帮助。
