Redeploying only hello function fails with an error

[cscetbon]

I'm testing that plugin and I have issues just following the tutorial. The first issue I met is regarding deploying to a namespace different from default #188 (comment).

The other issue I have is redeploying the function hello only. When I try I get the following

serverless deploy function -f hello
Serverless: Packaging function: hello...
Serverless: Excluding development dependencies...
Serverless: Redeploying hello...

The issue from line https://github.com/serverless/serverless-kubeless/blob/master/deploy/kubelessDeploy.js#L85 where description.package is undefined. I'm using the default serverless.yaml provided
I'm using version 0.9.2. I've been looking at that plugin a year ago and thought it was mature, but just following the tutorial fails..

I've met the problem as you too.

Hi @cscetbon , @donhui , replace python2.7 with python3.7. Runtime python2.7 does not exist any more.

Hi @sepetrov , I've replaced python2.7 with python3.7. But the problem still exist.

Hi @cscetbon , @donhui , replace python2.7 with python3.7. Runtime python2.7 does not exist any more.

Hi @sepetrov Can we create the serverless-kubeless template with python2.7 runtime and then edit it to python3.7?

or Is there any other workaround by which we can use python3 instead of python2 for serverless-kubeless?

Any help/references would be appreciated.
Thanks
