任何人都知道问题导致了什么？谢谢！

Answer 1

我遇到了同样的问题，并遇到了解决方案on this page on github。为了完整起见，评论/回答是：

这是上游包html5lib的一个问题...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。

不确定您为什么会遇到这个问题，但我会尝试使用BeautifulSoup选择您感兴趣的表格，并将其作为字符串传递给read_html()。例如：

import pandas as pd
import requests
from bs4 import BeautifulSoup

url = "http://www.checkee.info/main.php?dispdate="
res = requests.get(url)
soup = BeautifulSoup(res.content,'lxml')

table = soup.find_all('table')[7] # Select the table you're interested in
df = pd.read_html(str(table))[0]

在Python＆＃34;＆＃39;模块＆＃39;中读取html到数据框时出错对象没有属性＆＃39; _base＆＃39;＆＃34;
