Python: ImportError: lxml not found, please install it
提问by Jazz
I have the following code (in PyCharm (MacOS)):
我有以下代码（在 PyCharm (MacOS) 中）：
import pandas as pd
fiddy_states = pd.read_html('https://simple.wikipedia.org/wiki/List_of_U.S._states')
print(fiddy_states)
And I get the following error:
我收到以下错误：
/Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6 /Users/user_name/PycharmProjects/PandasTest/Doc3.py

ImportError: lxml not found, please install it
In Anaconda does appear installed the last version of lxml(3.8.0). Despite of that, I have tried to reinstall it by: 1)writing pip install lxmland 2)downloading the lxmlwheel corresponding to my python version (lxml-3.8.0-cp36-cp36m-win_amd64.whl), but in any case all remains the same (in the second case I get that it is not a supported wheel on this platform, even though the version of python is correct (3.6, 64 bits)).
在 Anaconda 中确实出现安装了lxml( 3.8.0)的最新版本。尽管，我曾尝试重新安装它：1）写作pip install lxml和2）下载lxml对应于我的Python版本（轮lxml-3.8.0-cp36-cp36m-win_amd64.whl），但在任何情况下都保持我得到相同的（在第二种情况下，它是not a supported wheel on this platform，即使python的版本是正确的（3.6，64位））。
I've read similar questions here (even with the same code above, since it's from a tutorial), but the problem still persists.
我在这里读过类似的问题（即使使用上面相同的代码，因为它来自教程），但问题仍然存在。

Based on the fact that the error is:
基于错误的事实是：
/Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6This means that you are working with python-3.6. Now usually the package manager for python-3.xis pip3. So you probably should install it with:
这意味着您正在使用python-3.6。现在通常python-3.x的包管理器是pip3. 所以你可能应该安装它：
pip3 install lxml回答by Ruxi Zhang
I got same error, it seems that my python3 was pointing to pandas in python2 (since I have not install pandas in python3). After doing pip3 install pandas and restarting a notebook, it worked fine.
我遇到了同样的错误，似乎我的 python3 指向了 python2 中的熊猫（因为我没有在 python3 中安装熊猫）。在执行 pip3 install pandas 并重新启动笔记本后，它工作正常。
