lxml我正在尝试在运行 RHEL 的超级计算机上安装调用我的帐户的 python 模块。
我愿意不是具有 root 访问权限或超级用户身份。
lxmllibxml2需要和的 dev/devel 版本，因为它们包含需要构建的libxslt头文件。lxml但是超级计算机已将非开发版本安装到其根目录中，因此我通过从源代码构建它们/usr将开发版本安装到我的目录中。home
两者都构建顺利，没有抛出任何错误，并且所有必需的头文件都在$HOME/usr/local/include/libxml2/libxml等中。
但是，每当我尝试时，它都会尝试在根目录中pip install lxml使用非 dev libxml2& ：libxslt/bin
[myusername@q0144 ~]$ pip install --install-option="--prefix=$HOME/python_modules" lxml
... (some unimportant messages) ...

还有几十行表明开发包未正确安装，因为它正在查找错误的包。
如何让系统使用我安装的libxml2/版本？libxslt
我什至$HOME/bin首先$HOME/usr在.cshrc.
为了确保涵盖所有基础，我还尝试按照源 tarball 中包含的文档lxml中的说明从源代码构建：build.txt
[myusername@q0144 lxml-3.3.5]$ python setup.py build_ext -i -I $HOME/usr/include/libxml2/libxml --without-cython --with-xslt-config=$HOME/usr/local/bin/xslt-config

所以我基本上遇到了同样的问题，/user/local/lib而不是我的$HOME/user等目录。
我该如何解决这个问题？
答案1
确保bin两个包 (libxml2/libxslt) 的子目录都位于您的PATH.它们包含*-config在编译 lxml 期间使用的脚本来查找 libxml2/libxslt 的安装位置。
[pdobrogost@host /]$ echo $PATH
(...):/opt/libxslt-1.1.27/bin:/opt/libxml2-2.6.32/bin:(...)
[pdobrogost@host /]$ which xml2-config && which xslt-config
/opt/libxml2-2.6.32/bin/xml2-config
/opt/libxslt-1.1.27/bin/xslt-config
