我正在使用python-scrappy模块

执行示例报废

我用这个例子执行它http://doc.scrapy.org/en/0.14/intro/tutorial.html#intro-tutorial

Answer 1

Debian或Ubuntu（9.04或更早版本）

如果您正在运行Debian Linux，请以root身份运行以下命令：

apt-get install python-twisted python-libxml2 python-pyopenssl python-simplejson

然后：

easy_install -U w3lib

然后按照Install Scrapy中的说明进行操作。

Answer 2

我认为您需要安装twisted，因为找不到的conch模块可能是twisted.conch。
