我正在尝试使用 pandas 库中的 .read_html() 函数，并在我在 shell 中运行代码时不断收到此错误。我看到您需要安装 lxml，所以我使用 apt-get 进行了安装。但后来当我再次尝试运行它时，我得到了同样的错误。

(trusty)mdz5032@localhost:~$ sudo apt-get -y install python-lxml
[sudo] password for mdz5032:

python-lxml is already the newest version.

这是我正在使用的代码

import pandas as pd
import pandas_datareader.data as web
import quandl


df = quandl.get("FMAC/HPI_PA", authtoken="")

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

我取出了 api 密钥，但如果需要，可以发布它。

这是完整的追溯

sudo apt-get install python3-lxml

你已经为 python2 安装了 lxml，但是你的代码在 python3 下运行。
