lxml我正在嘗試在運行 RHEL 的超級電腦上安裝調用我的帳戶的 python 模組。
我願意不是具有 root 存取權或超級使用者身分。
lxmllibxml2需要和的 dev/devel 版本，因為它們包含需要建置的libxslt頭檔。lxml但是超級電腦已將非開發版本安裝到其根目錄中，因此我透過從原始程式碼建置它們/usr將開發版本安裝到我的目錄中。home
兩者都構建順利，沒有拋出任何錯誤，並且所有必需的頭文件都在$HOME/usr/local/include/libxml2/libxml等待中。
但是，每當我嘗試時，它都會嘗試在根目錄中pip install lxml使用非 dev libxml2& ：libxslt/bin
[myusername@q0144 ~]$ pip install --install-option="--prefix=$HOME/python_modules" lxml
... (some unimportant messages) ...

還有幾十行表示開發包未正確安裝，因為它正在尋找錯誤的套件。
如何讓系統使用我安裝的libxml2/版本？libxslt
我甚至$HOME/bin首先$HOME/usr在.cshrc.
為了確保涵蓋所有基礎，我還嘗試按照來源 tarball 中包含的文件lxml中的說明從原始碼建置：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樣的問題，/user/local/lib而不是我的$HOME/user等目錄。
我該如何解決這個問題？

確保bin兩個套件 (libxml2/libxslt) 的子目錄都位於您的PATH.它們包含*-config在編譯 lxml 期間使用的腳本來尋找 libxml2/libxslt 的安裝位置。
[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
