Aws-sam-cli: I am running inside virtualenv(Windows) when executing sam package results in an error.

[kyeljmd]

Description:

Steps to reproduce the issue:

1. Create a basic serverless code, and run in python
2. Create a template yaml.
3. perform sam package

Upon executing sam package in windows. I ended up getting this error.

hey @kyeljmd, whenever you can, mind sharing the following as I don't have a Windows machine handy in here?

• What's inside C:\Users\TEUSER\Envs\python2\Scripts\
• Are you able to successfully run either commands below inside/outside the virtualenv?
  
  
  
  • aws help
  
  
  • aws.cmd help
  
  
  • If aws.cmd fails you can either install system wide or inside your Virtualenv run `pip install awscli
  
  

sam package will execute aws CLI under the hood and if it can't find it'll fail which seems to be the case here - If that is confirmed, we should definitely improve the error messaging there.

---

An unrelated minor note though:

• As you're running inside VirtualEnv, you don't need to install packages using --user flag as VirtualEnv is self-contained already and this should work pip install aws-sam-cli

I'm getting the same error while running

sam package --template-file template.yaml --s3-bucket c21-peter-testing --output-template-file packaged.yaml

However, running aws cloudformation directly, it works fine
aws cloudformation package --template-file template.yaml --s3-bucket bucketname --output-template-file packaged.yaml
produces

Execute the following command to deploy the packaged template
aws cloudformation deploy --template-file D:\lambda\serverless-application-model\examples\apps\hello-world\packaged.yaml --stack-name <YOUR STACK NAME>

Also, the same error occurred when runing sam deploy while aws cloudformation deploy works fine.

hi peterpham complete the same problem. does you find a solution yet?

[peterpham]

no unfortunately. I used a workaround by running aws cloudformation deploy.
As it didn't work for my entire workflow, I am back to use serverless framework sls for the time being.

[ntpnhan]

Many thanks @heitorlessa,
I run 'pip install awscli' then run the sam package again, it work.

[EpicVoyage]

Can you run the aws command from your command line after pip install awscli? Keep in mind that you may have to close and re-launch the command shell.

[LacikIgor]

I can confirm that even if my aws-cli tools worked perfectly (other than SAM) I also had to pip install awscli, otherwise I was facing the same issue as the gentleman who asked the question

The error message could indeed be improved :)

Running windows 7

[eric-crossman]

As a new user, I found it confusing having to separately install the AWS CLI again via pip. Is there any interest in a patch to improve the error handling?

[sriram-mv]

Think this has been fixed with the PR: https://github.com/awslabs/aws-sam-cli/pull/786

Especially on windows, I think it was difference between looking for aws.exe and not aws.cmd

[jfuss]

Closing as #786 has been released already.
