Question

我正在尝试这段代码。

import pandas as pd

fiddy_states=pd.read_html('https://simple.wikipedia.org/wiki/List_of_U.S._states')

print(fiddy_states[0])

我收到以下错误：

    Traceback (most recent call last):

During handling of the above exception, another exception occurred:

我试过以下事情：卸载并安装certifi 堆栈溢出的相关答案中提到的所有其他步骤。仍然无法修复它。

请帮忙。

我遇到了同样的问题，经过一番搜索后，我发现了这个问题 https://bugs.python.org/issue28150

有一个命令行可运行的脚本（＆＃34; / Applications / Python 3.6 /安装Certificates.command＆＃34;），它使用pip来安装certifi，并在OpenSSL目录中创建一个符号链接，用于证明＆＃39;已安装捆绑位置。

这对我有用，也许你可以看看。
