我通过这个网站和其他网站搜索了我的问题的解决方案。不幸的是，给定的解决方案都没有帮助我。
我的问题如下。我想安装python lxml库，但每次都出错。
1）当我尝试在pycharm中安装lxml时，我得到了以下错误：
ERROR: b"'xslt-config' is not recognized as an internal or external command,\r\noperable program or batch file.\r\n"
2）当我尝试使用pip install lxml在命令行中安装lxml时，出现以下错误：
C:\Windows\system32>pip install lxml
Collecting lxml
