pip install -r requirements.txt报错ERROR: No matching distribution found for aiofiles==22.1.0

今天安装jumpserver时，在安装python模块时出错了

进度：pip install -r requirements.txt

报错：

ERROR: Could not find a version that satisfies the requirement aiofiles==22.1.0 (from versions: 0.2.1, 0.3.0, 0.3.1, 0.3.2, 0.4.0, 0.5.0, 0.6.0, 0.7.0, 0.8.0)

ERROR: No matching distribution found for aiofiles==22.1.0

 解决方法：

pip freeze > requirements.txt

#加阿里镜像

pip install -r requirements.txt -i https://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com
