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>

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
