Scrapy - 找不到名为mail.smtp的模块

Question

系统：Ubuntu 14.04

我使用命令sudo pip install scrapy安装了Scrapy。

我正在按照这里的教程进行操作。

当我在此步骤运行命令scrapy crawl dmoz时，出现以下错误:

你是否已经安装了Twisted？ - TheGeorgeous

尝试更新或重新安装Twisted。 - Artur Gaspar

@TheGeorgeous 看起来我没有它。请将其提供为答案，以便我可以接受并关闭问题。 - callmekatootie

Scrapy 依赖于 Twisted。奇怪的是它没有被安装。 - Artur Gaspar

Answer 1

我遇到了同样的问题。 安装twisted解决了这个问题。

sudo apt-get install python-twisted

我必须做的事情完全正确。谢谢你。 - Nabin

有没有一种使用 pip 安装它的方法？ - Batandwa

可能不行，因为python-twisted在pip上不可用。 - THIS USER NEEDS HELP

当安装Scrapy时，为什么这个不作为依赖项安装呢？Pip应该管理依赖关系，对吧？ - Jon Carter

Scrapy突然停止工作并抛出了这个邮件错误...但上述建议起作用了。 - larrywgray

Answer 2

Scrapy使用twisted.mail.smtp模块。安装twisted应该可以解决这个问题。
