Question

我之前使用过Anaconda来处理python，但是我开始使用虚拟环境。

我设置了virtualenv和virtualenvwrapper，并且一直在尝试为我想尝试的项目添加模块，特别是scrapy和lxml。

每次点击安装时，我都会遇到错误。

对于scrapy：

File "/home/philip/Envs/venv/local/lib/python2.7/site-packages/setuptools/command/easy_install.py", line 1003, in run_setup
    raise DistutilsError("Setup script exited with %s" % (v.args[0],))

distutils.errors.DistutilsError: Setup script exited with error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

对于lxml：

In file included from src/lxml/lxml.etree.c:346:0:

/home/philip/Envs/venv/build/lxml/src/lxml/includes/etree_defs.h:9:31: fatal error: libxml/xmlversion.h: No such file or directory

 include "libxml/xmlversion.h"

                               ^

compilation terminated.

我尝试在scrapy's documentation之后安装它，但是当我调用python的已安装模块时，scrapy仍未列出。

有什么想法吗？谢谢 - 非常感谢！

如果重要的话，请关注Ubuntu 13.10。我试过的其他模块安装得很好（虽然我只是为了少数人而去）。

Answer 1

我在Ubuntu 14.04中遇到了同样的问题。我已经用@jdigital链接的页面和@ user3115915指向的openssl-dev库解释了它。只是为了帮助别人：

sudo apt-get install libxslt1-dev libxslt1.1 libxml2-dev libxml2 libssl-dev
sudo pip install scrapy

Answer 2

就我而言，我解决了安装Manuel所提及的所有库以及额外库的问题：libffi-dev

Answer 3

更新自@Mario C.和@Manuel，

这是命令：

sudo apt-get install libxslt1-dev libxslt1.1 libxml2-dev libxml2 libssl-dev libffi-dev
sudo pip install scrapy

反复无法安装scrapy和lxml
