Scrapy - AttributeError: type object 'SettingsFrame' has no attribute 'ENABLE_CONNECT_PROTOCOL'
Scrapy - AttributeError: type object 'SettingsFrame' has no attribute 'ENABLE_CONNECT_PROTOCOL'
我在 Windows 上使用 Conda 环境。
刚安装完scrapy，我就在试用了。我在启动 scrapy shell 时遇到问题。
我输入scrapy shell "url"。我收到此错误消息：

有人向我解释这个错误吗？我在 SOF 看到一些帖子，很多人建议升级版本。遇到这种情况，我该怎么办？
我也遇到过。
首先尝试升级 h2，conda install -c conda-forge h2，
或者用 pip
pip uninstall h2
pip install h2==3.2.0
如果它不起作用，您可以这样做（这样做需要您自担风险，但这是我所做的并且它起作用了）：
打开“C:\Users\jjang\anaconda3\envs\first_scrapy\lib\site-packages\hyperframe\frame.py”
在“class SettingsFrame(Frame)”中添加以下行：
ENABLE_CONNECT_PROTOCOL = 0x01
保存文件并重新启动 IDE/terminal。
