aws-sam-cli: Hello world fails to build on Windows 10

Description

Python version of hello-world fails to build on Windows 10

Steps to reproduce

I can reproduce it in 2 ways. First way to reproduce:

sam init --runtime=python3.6 cd sam-app sam build --use-container

Can also be reproduced if I do the following: Step 0: (if necessary to clean up from above steps, in WSL): cd …;rm -rf sam-app sam init --runtime=python3.6 cd sam-app sam build sam local start-api --debug

This seems to only happen on my machine, but I don’t know how to recover. I tried to reinstall Python, the AWS CLI, SAM CLI, docker, and I’m having no luck.

Observed result

Expected result

Running server I believe on port 3000, returning “hello world”.

Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

Windows 10

So I installed sam-cli using msi and I was getting this issue. I tried everything in this thread and reinstalled everything, but the issue persisted nevertheless.

It turns out sam-cli is using a different python installation at runtime, and for me, it is located in
C:\Program Files\Amazon\AWSSAMCLI\runtime
This thing uses docker-4.0.4 which is outdated so I ran ./python -m pip install --upgrade docker in the runtime folder, and after upgrading to docker-5.0.3 I am longer facing the issue.

I don’t see the option to reopen this issue.

I remember working around the issue by: downgrading pypiwin32=220, but that was around 10 months ago. Others are saying downgrading pywin32 from version 225 to 224 worked for them.

I also asked AWS to document this problem and the solution, but that did not happen, either.

@mkislik Thanks! It looks like this issue was caused by an out-of-date version of the ‘docker’ pip package.

None of the following had any effect:

Remove python 3.6.8 and install python 3.6.7.
Update the awscli package: python -m pip install --upgrade awscli
Install the aws-sam-cli package: python -m pip install aws-sam-cli
Restart my machine.

But this fixed the issue:

Update the docker package from 3.4.0 to 3.7.0: python -m pip install --upgrade docker

I’m investigating the new error now, but it looks like an unrelated issue. Edit: Un-sharing and then re-sharing my C drive with Docker fixed the new issue.

So the question is: Why was my docker dependency out of date despite just installing SAM CLI 0.10 yesterday? Should the minimum version be updated in SAM CLI’s dependencies?
