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：

pip install awscli --upgrade --user

aws

依然提示：
