我无法将 AWS SAM CLI 从 0.2.8 升级到 0.6.1。
我按照这里提到的说明进行操作： https ://github.com/awslabs/aws-sam-cli/blob/develop/docs/installation.rst
$ sam -version
A newer version of the AWS SAM CLI is available!
Your version: 0.2.8
Latest version: 0.6.1
See https://github.com/awslabs/aws-sam-local for upgrade instructions
sam version 0.2.8
按照说明我需要删除旧版本
$ npm uninstall -g aws-sam-local
up to date in 0.044s
步骤 1. 验证 Python 版本是 2.7 还是 3.6。
$ python --version
Python 3.6.5
步骤 2. 验证 Pip 是否已安装。
$ pip --version
pip 18.1 from /usr/local/lib/python3.6/site-packages/pip (python 3.6)
步骤 3. 安装 aws-sam-cli
$ pip install --user aws-sam-cli

步骤 4. 调整您的 PATH
我添加到我的 .bash_profile
USER_BASE_PATH=$(python -m site --user-base)
export PATH=$PATH:$USER_BASE_PATH/bin
步骤 5. 验证 sam 是否已安装
$ sam --version
A newer version of the AWS SAM CLI is available!
Your version: 0.2.8
Latest version: 0.6.1
See https://github.com/awslabs/aws-sam-local for upgrade instructions
sam version 0.2.8
不好了！这一切都是徒劳的！请帮忙！我错过了什么？
