我正在尝试使用 pip 安装 lxml。我有 Windows 11 和 Python 版本 python-3.10.2-amd64。我也在使用 Visual Studio Code (VSC)。我意识到我需要 lxml 从我的 VSC 终端中的错误消息：
Traceback (most recent call last):
File "Vegas.py", line 13, in <module>
soup = BeautifulSoup(html_text, 'lxml')
File "/usr/lib/python3.6/site-packages/bs4/__init__.py", line 248, in
__init__
% ",".join(features))
bs4.FeatureNotFound: Couldn't find a tree builder with the features you
requested: lxml. Do you need to install a parser library?
从那里，我尝试使用 VSC 终端中的命令安装 lxml：
pip install lxml
我收到此错误消息：

于是我就去这个网站下载了libmxl2和libxslt：https://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml https://www.lfd.uci.edu/%7Egohlke/pythonlibs/#lxml。下载 lxml-4.7.1-cp310-cp310-win_amd64.whl 版本（因为它与我的 python 版本匹配）后，我尝试在 Windows 命令提示符中使用以下命令：
pip install lxml-4.7.1-cp310-cp310-win_amd64.whl
我得到了这个结果：
lxml is already installed with the same version as the provided wheel.
Use --force-reinstall to force an installation of the wheel.
然后我执行了相同的命令，但添加了 --force-reinstall ，它表示已成功安装 lxml-4.7.1。然后我回到 VSC 终端，运行“pip install lxml”并收到与之前相同的错误消息。所以我在 VSC 终端中尝试了“pip install lxml-4.7.1-cp310-cp310-win_amd64.whl”命令并收到此错误：
ERROR: lxml-4.7.1-cp310-cp310-win_amd64.whl is not a supported wheel on this platform.
然后我想我应该尝试win32版本，因为我有Intel处理器。所以我在命令提示符下运行这个命令：
pip install lxml-4.7.1-cp310-cp310-win32.whl
我收到此错误消息：
ERROR: lxml-4.7.1-cp310-cp310-win32.whl is not a supported wheel on this platform.
所以我很茫然。任何帮助是极大的赞赏！
