无服务器:找不到 python3.7！尝试 pythonBin 选项 [英] Serverless: python3.7 not found! Try the pythonBin option

问题描述

我正在尝试使用无服务器框架和 Python 开发一个简单的无服务器应用程序.

I'm trying to develop a simple serverless app using Serverless framework and Python.

这是我的 serverless.yml

service: hello-world

provider:
  name: aws
  region: us-west-2
  runtime: python3.7
  environment:
    DB_ENDPOINT: 
    DB_USERNAME: 
    DB_PASSWORD: 

plugins:
  - serverless-python-requirements

functions:
  hello:
    handler: handler.trial_registration

当我运行 sls deploy 时出现以下错误

When I run sls deploy I get following error

Serverless: Generated requirements from /home/ganesh/code/hello-world/requirements.txt in /home/ganesh/code/hello-world/.serverless/requirements.txt...
Serverless: Installing requirements from /home/ganesh/.cache/serverless-python-requirements/5c625dc5f843b3bb1163fd11989b43fb3cbca4299219c6ef399108fb36e56a2f_slspyc/requirements.txt ...

推荐答案

AWS (Elastic Beanstalk) 尚未包含 python3.7 (31/08/2019)，请尝试将您的 Python 版本降级到 3.6 并重试.

AWS (Elastic Beanstalk) didn't yet include python3.7 (31/08/2019), try to downgrade your python version to 3.6 and try again.
