Pandas: read_html

Running Python 3.4 on a mac

New pyvenv

pip install pandas
pip install lxml
pip install html5lib
pip install BeautifulSoup4

Then run your example and it should work:

import pandas as pd
import html5lib
f_states=   pd.read_html('https://simple.wikipedia.org/wiki/List_of_U.S._states') 

Also consider conda installing your required packages at https://www.continuum.io/downloads. Instead of pip installing, you would conda install your packages.

$ conda install html5lib
