Can anyone explain why I am getting this error [ImportError: lxml not found, please install it]

Question

我正在尝试使用 pandas 库中的 .read_html() 函数，并且当我运行 shell 中的代码时不断出现此错误.我看到您需要安装 lxml，所以我使用 apt-get 安装了它。但是后来当我再次尝试运行时，我遇到了同样的错误。

(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 钥匙，但如果需要的话可以 post。

这是完整的回溯

sudo apt-get install python3-lxml

您已经为 python2 安装了 lxml，但您的代码是 python3 下的运行。
