Python pandalarıyla ilgili sorunlar: read_html ve python3-lxml yüklemesi

Question

Aşağıdaki kodu çalıştırmaya çalışıyorum, boşuna. Benim bilgime göre, herhangi bir sözdizimi hatası yoktur. Bunun gerçekleşmesini niçin çok emin

Traceback (most recent call last):

File "C:/Users/Dave/Documents/Python Files/helloworld.py", line 15, in fiddy_states = pd.read_html(' http://simple.wikipedia.org/wiki/List_of_U.S._states ')

File "C:\Python35\lib\site-packages\pandas\io\html.py", line 874, in read_html parse_dates, tupleize_cols, thousands, attrs, encoding)

File "C:\Python35\lib\site-packages\pandas\io\html.py", line 726, in _parse parser = _parser_dispatch(flav)

File "C:\Python35\lib\site-packages\pandas\io\html.py", line 685, in _parser_dispatch raise ImportError("lxml not found, please install it")

ImportError: lxml not found, please install it

değil tüm paketler bu kodu çalıştırmak için gerekli olan (olmalı) gibi: Bu kodu çalıştırdığınızda

import quandl 
import pandas as pd 

fifty_states =pd.read_html('https://simple.wikipedia.org/wiki/List_of_U.S._states') 
print(fifty_states) 

aşağıdaki hatayı alıyorum. Paketler yüklenemediğinden, lxml ve python3-lxml yükleme sorunlarım var. Ben LXML için uygun bir alternatiftir okudum 'html5lib', ilaveten

python-dev libxml2-dev libxslt1-dev zlib1g-dev

: yedek olarak, aşağıdaki monte ettik.

Bu noktada başka ne yapacağını bilmiyorum, çünkü benzer düzeltmeleri ararken (yani lxml'yi yükledikten sonra) benim için geçerli değil (komut satırında pip aracılığıyla herhangi bir biçimde lxml yükleyemiyorum).

Herhangi bir yardım çok takdir edilmektedir.

Düzenleme: Bilgisayarımda hiç lxml'un yüklü olmadığı anlaşılıyor. Bu garip çünkü pip install lxml aracılığıyla yükleyemiyorum. çalışırken alıyorum hata günlükleri Here're bir yükleme: Anlıyorum ve read_html()lxml kullanmak başarısız olursa docs göre, bu html5lib geri düşmesi gerektiğini kadarıyla
