未定義的符號：xmlMemDisplayLast誤差LXML

我收到通過PIP安裝LXML這些錯誤：未定義的符號：xmlMemDisplayLast誤差LXML

假設有些包不符合要求，我試圖通過yum更新它們：

已安裝的軟件包libxml2-2.6.26-2.1.25.el5_11.i386和最新版本

包裝的libxslt-1.1.17-4.el5_8.3.i386已經安裝了最新版本

我在CentOS上用Python 3.5.1。有沒有簡單的方法來安裝它？

也許值得尋找另一個百勝回購？

如果我嘗試通過這兩個軟件包的https://serverfault.com/questions/266927/install-libxml2-2-7-x-on-centos-5-x#305682手動安裝（libxslt 1.1.23和libxml 2-2.7.2）以使它們保持最新，那麼在嘗試在Python 3.5中使用lxml時會出現此錯誤：

>>> from lxml import html 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "/usr/local/lib/python3.5/site-packages/lxml/html/__init__.py", line 54, in <module> 
    from .. import etree 
ImportError: /usr/local/lib/python3.5/site-packages/lxml/etree.cpython-35m-i386-linux-gnu.so: undefined symbol: xmlMemDisplayLast

怎麼樣'libxslt'？這是你應該安裝的其他庫。 – schwobaseggl

@schwobaseggl是的，已經安裝了'Package libxslt-1.1.17-4.el5_8.3.i386已安裝並且最新版本' – Zeno

鑑於消息「錯誤最低要求版本的libxml2是2.7.0'且錯誤最低要求版本的libxslt是1.1.23'，你是說你的問題是你不知道如何獲得滿足安裝在CENTOS上的這些要求的軟件包？這有助於：http://serverfault.com/questions/266927/install-libxml2-2-7-x-on-centos-5-x#305682？ – snakecharmerb

src/lxml/includes/etree_defs.h:19:4: error: #error minimum required version of libxml2 is 2.7.0 
src/lxml/includes/etree_defs.h:28:4: error: #error minimum required version of libxslt is 1.1.23

的libxml2-devel的&的libxslt-devel的的版本不滿足要求。

嘗試yum install libxml2-devel libxslt-devel

*假設有些軟件包不符合要求，我嘗試通過yum *更新它們，然後是太舊的軟件包版本。他們需要幫助尋找新的軟件包。 –

這給了我「已安裝和最新版本」 – Zeno
