Collecting awscli
Could not find a version that satisfies the requirement awscli (from versions: )
No matching distribution found for awscli
按照官方文档：https://docs.aws.amazon.com/zh_cn/cli/latest/userguide/installing.html
使用以下命令安装：
$ pip install awscli --upgrade --user
之前一天尝试就有错误，
以下命令也尝试了：
sudo pip3 install awscli --upgrade --user
得到相同的错误，
但是隔了一天，今天再执行却又可以了，
然而命令执行成功，awscli 却不知道安装到哪里去了，
执行 aws 提示找不到命令。
原来是要升级 pip
sudo pip install --upgrade pip
然后再执行
sudo pip install awscli --upgrade --user
安装。
后来又转到 root 用户下，不加 sudo 安装，
输出都一样：

命令执行完成，再执行：
aws
依然提示：
-sh: aws: command not found
