前几天我决定安装一个名为lxml的HTML解析库。我安装了它，但得到一个错误，说我没有安装微软c++构建工具。我安装了Build Tools，它解决了安装大多数库的问题，但没有解决LXML的问题。当我尝试安装库时，我得到这个错误:
× Running setup.py install for lxml did not run successfully.
│ exit code: 1
╰─> [96 lines of output]
Collecting lxml
Using cached lxml-4.9.1.tar.gz (3.4 MB)
Preparing metadata (setup.py) done
Installing collected packages: lxml
DEPRECATION: lxml is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

我尝试安装libxml2库，但是如果我尝试使用命令安装库，我会得到一个错误:
pip install --user libxml2-python
以及使用命令
安装库时出现的错误:pip install --user libxml2-python3

我遇到了同样的问题，我做了下一个:
-
pip install lxml-对我不起作用-我不得不从这里(https://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml)从我的机器上的版本python (lxml-4.9.0-cp311-cp311-win_amd64)下载xml。whl -我有python 3.11-64位)
-
我安装了文件- (pip install C:UsersdalerDownloadslxml-4.9.0-cp311-cp311-win_amd64.whl)键入路径是您下载的lxml。
-
然后，我可以安装我需要的库在我的情况下(pip安装yfinance)最终被安装，因为我有同样的问题比你。
