想玩玩AWS CLI，就从https://aws.amazon.com/cli/装了一个，但是一执行就是出LookupError: unknown encoding: cp65001错误，查了一下据说是Python2.7导致的。 首先去https://www.python.org/下载了最新的Python3.7.0。然后重新安装AWS CLI，依旧出错，只好卸载。 查看是否安装pip，结果发现没有。根据https://packaging.python.org/tutorials/installing-packages/中的提示下载了get-pip.py，执行python get-pip.py，成功安装好pip。

C:\>pip --version
pip 10.0.1 from c:\users\mryqu\appdata\local\programs\python\python37-32\lib\site-packages\pip (python 3.7

最后使用pip安装AWS CLI:

C:\>pip install awscli

使用AWS CLI，貌似好用，就是help命令报内存不足！

C:\>aws --version
aws-cli/1.15.49 Python/3.7.0 Windows/2008ServerR2 botocore/1.10.48

C:\>aws configure list

C:\>aws help
Not enough memory.

最后发现，我在AWS上的SAS联合账户根本没权限获得AWS Access Key ID和AWS Secret Access Key，这样就没法按照Configuring the AWS CLI进行配置了。棋差一招，只好不玩了。
