在pandas

Question

这段代码给了我一个错误：

代码：

import pandas as pd

fiddy_states = pd.read_html("https://simple.wikipedia.org/wiki/List_of_U.S._states")

错误：

ImportError: html5lib not found, please install it

虽然我安装了html5lib，lxml和BeatifulSoup4库并进行了更新。

Answer 1

考虑使用xpath表达式使用lxml解析html表，然后将列表合并到数据框中：

val process: ()(implicit cache: Cache) => String = processF _ // syntax error

Answer 2

尝试并使用conda来安装html5lib而不是pip。为我工作。
