在Python“html5lib not found”中将html读取到数据框时出错

Question

在尝试读取html数据框时，我遇到了关于html5lib的以下错误。

这是代码：

!pip install html5lib
!pip install lxml
!pip install beautifulSoup4

import html5lib
import lxml
from bs4 import BeautifulSoup

table_list = pd.read_html("http://www.psmsl.org/data/obtaining/")

这是错误：

如果您阅读了错误消息，则表明您没有安装html5lib。做：

pip install html5lib
