Question

我正在通过有关udemy的jupyter笔记本进行工作，此主题是关于熊猫的，关于以下问题之一，我会收到此错误消息：ImportError                               Traceback (most recent call last)<ipython-input-6-dc8b64eb545d> in <module>()----> 1 df = pd.read_html('http://www.fdic.gov/bank/individual/failed/banklist.html')c:\users\phillip.desktop-did4ci8\appdata\local\programs\python\python37-32\lib\site-packages\pandas\io\html.py in read_html(io, match, flavor, header, index_col, skiprows, attrs, parse_dates, tupleize_cols, thousands, encoding, decimal, converters, na_values, keep_default_na, displayed_only)    985                   decimal=decimal, converters=converters, na_values=na_values,    986                   keep_default_na=keep_default_na,--> 987                   displayed_only=displayed_only)c:\users\phillip.desktop-did4ci8\appdata\local\programs\python\python37-32\lib\site-packages\pandas\io\html.py in _parse(flavor, io, match, attrs, encoding, displayed_only, **kwargs)    791     retained = None    792     for flav in flavor:--> 793         parser = _parser_dispatch(flav)    794         p = parser(io, compiled_match, attrs, encoding, displayed_only)    795 c:\users\phillip.desktop-did4ci8\appdata\local\programs\python\python37-32\lib\site-packages\pandas\io\html.py in _parser_dispatch(flavor)    749     else:    750         if not _HAS_LXML:--> 751             raise ImportError("lxml not found, please install it")    752     return _valid_parsers[flavor]    753 ImportError: lxml not found, please install it（我正在使用python 3.7，我已经下载了anaconda）然后，我尝试使用以下命令在命令提示符中安装lxml：pip3 install lxml我不确定如何解决此问题。
