However, when I try to run the demo:

$ bulker load demo
Using default config. No config found in env var: BULKERCFG
Bulker config: /home/lgatto/.local/lib/python3.7/site-packages/bulker/templates/bulker_config.yaml
Got URL: http://hub.bulker.io/bulker/demo.yaml

    path = os.fspath(path)
TypeError: expected str, bytes or os.PathLike object, not NoneType

Any help would be appreciated.

try running:

export BULKERCFG="bulker_config.yaml"
bulker init -c $BULKERCFG

before bulker load ... looks like I may have a problem if you haven't already set up a config file...

[lgatto]

Yes, thank you, that solved it:

➜  ~ export BULKERCFG="bulker_config.yaml"
➜  ~ bulker init -c $BULKERCFG
Guessing container engine is docker.
Wrote new configuration file: bulker_config.yaml
➜  ~ bulker load demo
Bulker config: bulker_config.yaml
Got URL: http://hub.bulker.io/bulker/demo.yaml
Executable template: /home/lgatto/templates/docker_executable.jinja2
Loading manifest: 'demo'. Activate with 'bulker activate demo'.
Commands available: cowsay, fortune

and

➜  ~ bulker activate demo
Bulker config: bulker_config.yaml
Activating bulker crate: demo
