python - 在 Python "' 模块中将 html 读取到数据框时出错模块'对象没有属性 '_base'“

Question

我在尝试从 url(链接 here)读取表格时遇到此错误。

代码如下:

import pandas as pd
link = "http://www.checkee.info/main.php?dispdate="
c=pd.read_html(link)

返回的错误是:AttributeError: 'module' object has no attribute '_base'

特别是

谁知道是什么问题导致的？谢谢!

我刚刚遇到了同样的问题，并找到了解决方案 on this page on github .为了完整起见，评论/答案是:

这是上游包 html5lib 的问题...要修复，强制降级到旧版本:

pip install --upgrade html5lib==1.0b8

这解决了我的问题。
