Question

我是最近对使用scrapy感兴趣的linux转换器。

jeremy@jeremy-Lenovo-G580:~/Dropbox/projects/scrapy_stuff$ uname -a
Linux jeremy-Lenovo-G580 3.5.0-52-generic #79~precise1-Ubuntu SMP Fri Jul 4 21:03:49 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

为此目的，我安装了python 2.7

$ python -V
Python 2.7.3

然后安装pip（使用sudo easy_install pip）然后使用它来安装scrapy0.24

sudo pip install scrapy

scrapy工作了一段时间，我在http://doc.scrapy.org/en/latest/intro/tutorial.html处完成了教程。每当scrapy运行时就会出现关于service_identity的抱怨，所以我用pip install安装了它（除非它在某个日志中，否则没有输出）。出于某种原因（也许是service_identity？），scrapy破了 -

$ scrapy -V
Traceback (most recent call last):

    class AttributeValue(univ.Any): pass

所以从http://doc.scrapy.org/en/latest/topics/ubuntu.html#topics-ubuntu我尝试首先卸载（sudo pip uninstall scrapy）然后

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 627220E7
echo 'deb http://archive.scrapy.org/ubuntu scrapy main' | sudo tee /etc/apt/sources.list.d/scrapy.list
sudo apt-get update && sudo apt-get install scrapy-0.24

并尝试使用pip install / uninstall卸载/ resintalling scrapy几次，也尝试了easy_install scrapy，然后尝试使用

进行更新

 sudo pip install -U scrapy

似乎与

同义

sudo pip intall --upgrade scrapy

（虽然第一次尝试安装我发现scrapy的旧版本正在运行，已经安装了更新的版本，并且在它被删除之后是唯一一次我让scrapy运行，所以我怀疑可能更新会修复事情再次）

$sudo pip install -U scrapy

所以，我会尝试安装libxml2和libxslt的开发包，但在这一点上并不乐观 - 我宁愿陷入一个兔子洞而且还不清楚是什么打破了工作scrapy的第一个位置..任何帮助表示赞赏，我的棕色头发变灰，灰色变白，白色燃烧。

也许我应该尝试在我设置的Windows虚拟机上运行python和scrapy（这非常简单顺便说一句）但它有点挫败了切换到linux的目的（这是我更接近源码很多我感兴趣的项目，以及开放的方面）

好的，所以我试过了

sudo apt-get install libxml2-dev
sudo apt-get install libxslt1-dev 
sudo apt-get install python2.7-dev

但scrapy仍然因为属性错误而死亡：模块对象没有属性'any'

Answer 1

重新安装ubuntu会照顾它，也许是极其有效的。我安装了ubuntu14LTS而不是我开始使用的12LTS。

之后才打嗝

$sudo apt-get install python-pip
$sudo pip install scrapy
...
twisted/runner/portmap.c:10:20: fatal error: Python.h: No such file or directory

但是

 sudo apt-get install build-essential python-dev

照顾它。希望这次scrapy可以工作一个多小时。花了2天好吗？

Answer 2

我在Ubuntu 14.04上遇到过这个问题。我确定已为 service_identity 16.0.0 安装了所有要求;列出here。我错过了 pyasn1 ， pyasn1-modules （通过pip安装），但忽略了 attrs 。删除 service_identity 并重新安装它选择了该程序包：

yes | pip uninstall service_identity; pip install service_identity

但是，使用pip＆service_identity的升级功能无法解决问题。
