如何在linux上没有管理权限的情况下安装lxml for python？

Question

我只需要一些不在主机上的软件包（以及我和linux ......我们......我们没有花太多时间在一起......）。

我用来安装他们像：

# from the source 
python setup.py install --user 

或

# with easy_install 
easy_install prefix=~/.local package 

但它不与LXML工作。我在生成过程中得到了很多的错误：

x:~/lxml-2.3$ python setup.py build

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

http://lxml.de/installation.html说，它有一定的相关性。但如何在没有管理权限的情况下安装它们

Answer 1

如果你没有管理员权限，无法说服安装相关的包，为你的管理员，你有两个选择：

选项1 - 下载源libxml2 and libxslt和编译你的$HOME下进行安装在某个地方，然后针对这些副本构建python-lxml。

这是一个非常相关的例子，因为如果你错过了更多的依赖关系，你可能会长时间下载/编译。

选项2 - 下载与服务器上使用的Linux相同发行版的二进制包，并将内容解压缩到您的主目录下。

例如，如果你正在运行Ubuntu清醒，你会先找出你的操作系统正在使用的版本，然后下载你缺少的包：

% uname -m 
x86_64 
% aptitude show libxml2 | grep Version 
Version: 2.7.6.dfsg-1ubuntu1.1 

下一页下载您需要的软件包

% mkdir root ; cd root 
% wget http://us.archive.ubuntu.com/ubuntu/pool/main/libx/libxml2/libxml2_2.7.6.dfsg-1ubuntu1.1_amd64.deb 
% wget http://us.archive.ubuntu.com/ubuntu/pool/main/libx/libxslt/libxslt1.1_1.1.26-6build1_amd64.deb 
% wget http://us.archive.ubuntu.com/ubuntu/pool/main/l/lxml/python-lxml_2.2.4-1_amd64.deb 

将内容提取和合并的LXML天然和纯Python代码和移动至共享库到顶部，然后取出所提取的内容：

从Ubuntu服务器直接0

% dpkg-deb -x libxml2_2.7.6.dfsg-1ubuntu1.1_amd64.deb . 
% dpkg-deb -x libxslt1.1_1.1.26-6build1_amd64.deb . 
% dpkg-deb -x python-lxml_2.2.4-1_amd64.deb . 
% mv ./usr/lib/python2.6/dist-packages/lxml . 
% mv ./usr/share/pyshared/lxml/* lxml 
% mv ./usr/lib . 
% rm *.deb 
% rm -rf usr 

最后，要使用这些文件，您需要将LD_LIBRARY_PATH和PYTHONPATH环境变量设置为指向$HOME/root。将这些在你~/.bashrc（或同等），所以它们是永久的：

% export LD_LIBRARY_PATH=$HOME/root/lib 
% export PYTHONPATH=$HOME/root 

您可以验证共享库正在使用中发现ldd（如果它安装）：

% ldd $HOME/root/lxml/etree.so | grep $HOME 
libxslt.so.1 => /home/user/root/lib/libxslt.so.1 (0x00007ff9b1f0f000) 
libexslt.so.0 => /home/user/root/lib/libexslt.so.0 (0x00007ff9b1cfa000) 
libxml2.so.2 => /home/user/root/lib/libxml2.so.2 (0x00007ff9b19a9000) 

那么你准备测试Python：

% python 
>>> from lxml import etree
