在 Python 中将 html 读取到数据框时出错“找不到 html5lib”

Question

在尝试读取 html 数据框时，我遇到了有关 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：

ImportError                               Traceback (most recent call last)

    738     for flav in flavor:

    740         p = parser(io, compiled_match, attrs, encoding)

如果您阅读错误消息，则说明您尚未html5lib安装。做：

pip install html5lib

在您的终端中。

如果您从 jupyter notebook 调用（就像使用 一样!），请尝试重新启动内核以加载软件包。
