将 html 读取到 Python 中的数据框时出错“html5lib 未找到”

Question

我在尝试读取 html 数据帧时遇到了有关 html5lib 的以下错误。

代码如下：

!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)
<ipython-input-68-e24654a0a301> in <module>()
----> 1 table_list = pd.read_html("http://www.psmsl.org/data/obtaining/")

    738     for flav in flavor:

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

如有任何帮助，我们将不胜感激。谢谢

如果您阅读了错误消息，则说明您没有安装 html5lib。做：

pip install html5lib

在您的终端中。

如果您是从 jupyter notebook 调用（就像您使用 ! 所做的那样），请尝试重新启动内核以加载包。

我运行当我给了我试图打开的本地文件的错误路径时，我陷入了这个错误。所以还要确保你指向正确的地方！
