如何在linux上安装lxml for python而不具有管理权限？

我只需要一些主机上没有的软件包（我和linux…我们…我们没有花太多时间在一起…）

我以前安装它们的方式如下：

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

或

但它不适用于lxml。我在构建过程中遇到很多错误：

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

表示它有一些依赖项。但是如何在没有管理权限的情况下安装它们呢？

如果您没有管理权限，并且无法说服管理员为您安装相关软件包，那么您有两种选择：

选项1-下载源代码，编译并安装在

$HOME

的某处，然后根据这些副本构建python lxml

这是一个非常复杂的例子，因为如果您缺少更多的依赖项，您可能需要下载/编译很长时间

选项2-下载服务器上使用的相同Linux发行版的二进制软件包，并提取主目录下的内容

例如，如果您运行的是UbuntuLucid，您首先会发现您的操作系统正在使用的版本，然后下载您丢失的软件包：

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

接下来直接从Ubuntu服务器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

提取内容并合并lxml本机和纯python代码，将共享库移到顶部，然后删除提取的内容：

% 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

。将它们放在您的

~/.bashrc

（或等效文件）中，以便它们是永久性的：

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

您可以使用

ldd

（如果已安装）验证是否找到共享对象：

然后，您就可以测试Python了：

% python
>>> from lxml import etree

你在virtualenv上试过吗？我在debian上。谢谢，我试试看。

% 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)

% python
>>> from lxml import etree
