请问，V2.1.0-alpha2 版本安装失败

1. Using pip installation (1) pip install quantaxis 所拉取的版本是 quantaxis-1.10.19 (2) pip install quantaxis==2.1.0a2 或 pip install quantaxis==2.1.0，没有该版本 ERROR: No matching distribution found for quantaxis==2.1.0a2
2. Source code installation (1) No matching distribution found for alphalens>=0.4.3，alphalens的版本 (from versions: 0.1.0, 0.1.2, 0.2.1, 0.3.0, 0.3.2, 0.3.3, 0.3.4, 0.3.6, 0.4.0)，没有0.4.3以上的版本 (2) 修改alphalens==0.4.0，No matching distribution found for qanotify>=0.1.0 qanotify的版本(from versions: 0.0.1, 0.0.2) (3) 修改qaootify==0.0.2 后续安装成功
3. After installation, test whether it is successful

Check if QUANTAXIS is installed

import QUANTAXIS as QA print(f"QUANTAXIS version: {QA.version}")

AttributeError: module 'QUANTAXIS' has no attribute 'version'
