如何在Ubuntu上安装lxml

Question

我在Ubuntu 11上使用easy_install安装lxml时遇到了困难.

当我输入时,$ easy_install lxml我得到:

Searching for lxml
Reading http://pypi.python.org/simple/lxml/
Reading http://codespeak.net/lxml
Best match: lxml 2.3
Downloading http://lxml.de/files/lxml-2.3.tgz
Processing lxml-2.3.tgz
Running lxml-2.3/setup.py -q bdist_egg --dist-dir /tmp/easy_install-7UdQOZ/lxml-2.3/egg-dist-tmp-GacQGy
Building lxml version 2.3.
Building without Cython.
ERROR: /bin/sh: xslt-config: not found

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

Using build configuration of libxslt 
In file included from src/lxml/lxml.etree.c:227:0:
src/lxml/etree_defs.h:9:31: fatal error: libxml/xmlversion.h: No such file or directory
compilation terminated.

似乎libxslt或libxml2没有安装.我已尝试按照http://www.techsww.com/tutorials/libraries/libxslt/installation/installing_libxslt_on_ubuntu_linux.php和http://www.techsww.com/tutorials/libraries/libxml/installation/installing_libxml_on_ubuntu_linux上的说明进行操作. PHP没有成功.

如果我尝试wget ftp://xmlsoft.org/libxml2/libxml2-sources-2.6.27.tar.gz我得到

<successful connection info>
==> SYST ... done.    ==> PWD ... done.
==> TYPE I ... done.  ==> CWD (1) /libxml2 ... done.
==> SIZE libxml2-sources-2.6.27.tar.gz ... done.
==> PASV ... done.    ==> RETR libxml2-sources-2.6.27.tar.gz ... 
No such file `libxml2-sources-2.6.27.tar.gz'.

如果我先尝试另一个,我会到达,./configure --prefix=/usr/local/libxslt --with-libxml-prefix=/usr/local/libxml2最终会失败:

checking for libxml libraries >= 2.6.27... configure: error: Could not find libxml2 anywhere, check ftp://xmlsoft.org/.

我试过两个版本2.6.27和2.6.29的libxml2没什么区别.

不遗余力,我已成功完成sudo apt-get install libxml2-dev,但这没有任何改变.

Answer 1

由于您使用的是Ubuntu,请不要理会这些源包.只需使用apt-get安装这些开发包.

apt-get install libxml2-dev libxslt1-dev python-dev

如果您对可能较旧的lxml版本感到满意,可以尝试一下

apt-get install python-lxml

并完成它.:)

Answer 2

我还必须在lxml编译之前安装lib32z1-dev(Ubuntu 13.04 x64).

sudo apt-get install lib32z1-dev

或者所有必需的包裹在一起:

sudo apt-get install libxml2-dev libxslt-dev python-dev lib32z1-dev

Answer 3

正如@Pepijn评论@Druska的答案,在ubuntu 13.04 x64上,没有必要使用lib32z1-dev,zlib1g-dev就足够了:

sudo apt-get install libxml2-dev libxslt-dev python-dev zlib1g-dev

Answer 4

我在Vagrant中使用pip安装了lxml,使用Ubuntu 14.04并遇到了同样的问题.即使安装了所有要求,我也会一次又一次地得到同样的错误.原来,我的VM默认只有很少的内存.1024 MB一切正常.

将此添加到您的VagrantFile和lxml应正确编译/安装:

config.vm.provider "virtualbox" do |vb|
  vb.memory = 1024
end

感谢sixhobbit的提示(参见:无法在Ubuntu 12.04上安装lxml).

Answer 5

对于Ubuntu 14.04

sudo apt-get install python-lxml

为我工作.

Answer 7

安装AKX提到的包后,我仍然遇到了同样的问题.解决了它

apt-get install python-dev

Answer 8

对于Ubuntu 12.04.3 LTS(精确穿山甲)我必须这样做:

apt-get install libxml2-dev libxslt1-dev

(注意libxslt1-dev中的"1")

然后我用pip/easy_install安装了lxml.
