無法在Windows上安裝python lxml（和libxml2）

Question

我正在嘗試在Windows上安裝lxml（pip install lxml）但我一直收到以下錯誤：

*****
Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?
****************************************************************************

Command "C:\Python34\python.exe -c "import setuptools, tokenize;__file__='C:\\Us
ers\\meme\\AppData\\Local\\Temp\\pip-build-m_doxfaj\\lxml\\setup.py';exec(comp
ile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __fi
le__, 'exec'))" install --record C:\Users\meme\AppData\Local\Temp\pip-ekkhc0id
-record\install-record.txt --single-version-externally-managed --compile" failed
 with error code 1 in C:\Users\meme\AppData\Local\Temp\pip-build-m_doxfaj\lxml

我試圖從這里下載 Windows的二進制文件（ ftp://ftp.zlatkovic.com/libxml/ ）並將它們添加到路徑但它似乎沒有幫助。

嘗試使用以下錯誤日志安裝時，手動下載lxml wheel（ http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml for cp34）文件也會失敗：

    return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x88 in position 2193: character maps to <undefined>

我在x64 win7機器上使用python34 32bit。

您可以從這里嘗試二進制文件。 首先執行pip install wheel然后pip install <filename.whl>來安裝下載的二進制文件。
