在 macOS python3.11 下安装报错

可否把

https://github.com/opendatalab/magic-html/blob/1c44bd5f92c488c24326fcc55167aaed15285439/requirements.txt#L2

改为 cchardet==2.2.0a2（见这个 issue）？否则在 python3.11 下报错。我显式指定安装 cchardet==2.2.0a2 后可以正常运行 README 里的例子。

报错信息如下：

@kkew3 感谢Kaiwen的建议，cchardet==2.2.0a2当前是预发布版本，下阶段抽取任务大规模验证后更新上线。

Same problem here. I can't even install it now.

@Tendo33 If the issue is that cchardet cannot compile in a higher version Python environment, you can try specifying the installation of cchardet alpha version. The specific steps are as follows:

1. pip install cchardet==2.2.0a2
2. pip install https://github.com/opendatalab/magic-html/releases/download/magic_html-0.1.2-released/magic_html-0.1.2-py3-none-any.whl
