Question

做的时候：

$ sudo pypy -m easy_install lxml

回复是：

Searching for lxml

[...snip...]

ERROR: /bin/sh: 1: xslt-config: not found

** make sure the development packages of libxml2 and libxslt are installed **

Using build configuration of libxslt 
/usr/lib/pypy/lib-python/2.7/distutils/dist.py:267: UserWarning: Unknown distribution option: 'bugtrack_url'

compilation terminated.
error: Setup script exited with error: command 'cc' failed with exit status 1

与此同时，sudo pip install lxml工作正常。

发生了什么？

感谢。

Answer 1

sudo apt-get install python-dev在ubuntu 13.04上为我修复了

Answer 2

$yum install python-lxml或apt-get install python-lxml 这解决了我的问题

Answer 3

我偶然发现了这个问题。

简短回答

Python2: $ python2.7 setup.py clean build --with-cython install
Python3: $ pip-3.3 install lxml

答案很长

假设pip install lxml应该适用于每个环境，无论您使用的是Python2还是Python3。

还需要考虑Cython：由于相关的效果提升，您肯定会喜欢lxml编译Cython。

由于我不知道的原因，Python2上的编译找不到Cython。为了更准确和绝对明确这个问题，下面的两个命令都不要使用Cython：

# DO NOT use these commands. I repeat: DO NOT use these commands.
$ pip-2.7 install lxml
$ easy_install-2.7 install lxml

所以，当我使用Python2时，你只有一个选择，据我所知，这是：从源代码编译，Luke！

# install build environment and dependencies
$ kernel_release=$( uname -r )
$ sudo apt-get install linux-headers-${kernel_release} build-essential -y
$ sudo apt-get install libxml2-dev libxslt1-dev -y

# Download from github and compile from sources
$ git clone --branch lxml-3.2.4 https://github.com/lxml/lxml
$ python2.7 setup.py clean build --with-cython install

Answer 4

我已通过安装的Ubuntu软件包pypy-dev处理此问题。

lxml不会使用easy_install在pypy下安装
