我尝试从github存储库进行安装，在编写!pip install -r requirements.txt时得到了相同的输出，我使用的是官方文档

Answer 1

查看日志错误是关于webkit-server库的，并查看GitHub发布的webkit-server库收到拉取请求，这帮助我安装webkit-server，然后安装dryscrape按照以下命令在Colab中安装它

命令1： !pip install git+https://github.com/niklasb/webkit-server.git@refs/pull/35/head

命令2： !pip install dryscrape

这将成功安装dryscrape
