无法安装环境lxml4.9.1

[MystFeng]

为了更好的解决问题，请认真回答下面的问题。等到问题解决，请及时关闭本issue。

• 问：请您指明哪个版本运行出错（github版/PyPi版/全部）？

答：全部

• 问：您使用的是否是最新的程序（是/否）？

答：是

（还没安装，所以中间问题我删了）

• 问：如果方便，请您描述出错详情，最好附上错误提示。

答：

我的python是3.12.2版本，半年前我安装过一次，也是这个问题。且pip版也不能运行之后输出config文件。

Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?

本程序需要用到lxml，这个我也无能为力。

[MystFeng]

最新版的lxml能运行吗

[dataabc]

应该可以。

[2OUMERTH]

这个问题可能是你本来有lxml了，但并非4.9.1版本的。你可以检查下你的lxml是什么版本的，然后把requirement.txt文件中的lxml改成对应版本，再次运行。关于config.jason文件不运行的问题，在文件夹下复制原有的config_simple文件，重命名为config后粘贴，在新的config里边更改参数，然后运行，在master的目录下执行命令：python -m weibo_spider

[Noah-Liu-1867]

你试着用“python -m weibo_spider”而不是“python3 -m weibo_spider”看看。
