如何让 aWS EB 实例使用已安装在实例上的 Python 3 版本？我无法让运行 Django 2.1+ 的 Python 3.6 的新环境运行。
本地（不在虚拟环境中）：
which python -> /usr/local/bin/python
python -V -> Python 2.7.15
which python3 -> /usr/local/bin/python3
python3 -V -> Python 3.6.5
which pip -> /usr/local/bin/pip
pip -V -> pip 18.0 from /usr/local/lib/python3.6/site-packages/pip (python 3.6)`
which pip3 -> /usr/local/bin/pip3
pip3 -V -> pip 18.0 from /usr/local/lib/python3.6/site-packages/pip (python 3.6)
虚拟环境中的本地mstFirst：
which python -> /Users/me/.virtualenvs/mstFirst/bin/python
which python3 -> /Users/me/.virtualenvs/mstFirst/bin/python
python -V -> Python 3.6.5
python3 -V -> Python 3.6.5
which pip -> /Users/me/.virtualenvs/mstFirst/bin/pip
which pip3 -> /Users/me/.virtualenvs/mstFirst/bin/pip3
pip -V -> pip 18.0 from /Users/me/.virtualenvs/mstFirst/lib/python3.6/site-packages/pip (python 3.6)
pip3 -V -> pip 18.0 from /Users/me/.virtualenvs/mstFirst/lib/python3.6/site-packages/pip (python 3.6)
aws --version -> aws-cli/1.16.9 Python/3.6.5 Darwin/17.7.0 botocore/1.11.9
eb --version -> EB CLI 3.14.4 (Python 3.6.5)
eb -list -> * mst-p3
eb -config ->

尝试时出错eb deploy，尝试运行时指向错误的 Python 版本（2.7）pip install -r requirements.py：

远程实例 ssh ( eb ssh)：
pyhthon -V -> Python 2.7.14
pyhthon3 -V -> Python 3.6.5
我尝试过的事情：
- 使用当前版本替换环境 AMI 并重建每个https://stackoverflow.com/a/47157777/1234721但环境错误，AMI 为“ami-0ff8a91507f77f867”，即“Amazon Linux AMI 2018.03.0 (HVM)，SSD 卷类型”
- 尝试接入 YAML 配置来切换 Python 版本
- 重新初始化使用
eb init
