`make build` fails: cp: cannot stat 'data-2': No such file or directory

On the current master (b49c6302d836d8e64ba0605e8cd7c88cd8eb1969) I get this on make build:

make: *** [Makefile:23: build] Error 1    

[Dorthu]

The build process requires both python2 and python3, and expects python to be python2. I've seen this error before if python --version returns 3.x. Try modifying this line of the Makefile to say python2 instead of python - although I'm hesitant to commit this change because many systems don't have a python2 by default (ideally the Makefile will detect what pythons are available and give reasonable errors if it can't build).

[themightychris]

What if it sniffed the versions of python, python2, and python3 and then set $PYTHON2 and $PYTHON3 for use in the rest of the Makefile?

[Dorthu]

yeah, I think that's what needs to happen. @asauber also encountered this when attempting to build with python pointed to python3 - I'm going to get on this shortly.

FYI, I wrote a habitat plan to work me around this: https://bldr.habitat.sh/#/pkgs/jarvus/linode-cli/latest

So on any Linux box now you can run:

# install hab CLI
curl -s https://raw.githubusercontent.com/habitat-sh/habitat/master/components/hab/install.sh | sudo bash

# install linode-cli and binlink it
hab pkg install -b jarvus/linode-cli

# profit!
linode-cli k8s-alpha create 

python, kubectl, and terraform binaries all get pulled and put into env by habitat

[asauber]

I had a copy of the Makefile that removed all ambiguity, but it got lost in my stash. I'll add a to-do item for myself to put up a PR.

Closing this issue as Python 2 support has been dropped in v5.25.0.
