Getting error "None of the given test nodes are connectable" about pytest-cloud HOT 13 CLOSED

when you pass
--cloud-node=@
what is the intent?
it should be the address

from pytest-cloud.

Yes, it is like this --cloud-node=username@IP address of the remote note

from pytest-cloud.

double-check if the node is connectable via ssh?

from pytest-cloud.

also, do you see that there's no python3.7 available on the node?

from pytest-cloud.

Yes, i have checked it, i am able to connect to the node via ssh.
i am passing this parameter so that it picks virtualenv from the local machine --cloud-virtualenv-path=local virtualenv path

from pytest-cloud.

if i do not provide --cloud-virualenv-path below error is thrown

UnboundLocalError: local variable 'n_m' referenced before assignment

from pytest-cloud.

local machines has python3.7.4 but remote machines has 3.6........does this cause problem ?

from pytest-cloud.

of course the same python version has to be available on all the nodes

from pytest-cloud.

but there's also a bug indeed:

if virtualenv_path:
n_m = NodeManager(config, specs=[])
virtualenv_path = os.path.relpath(virtualenv_path)

this has to be:

n_m = NodeManager(config, specs=[])
if virtualenv_path:
virtualenv_path = os.path.relpath(virtualenv_path)

in the pytest_cloud/plugin.py

please submit a PR

from pytest-cloud.

ok got it .... i will raise a PR

from pytest-cloud.

i have locally made the changes stated above and still getting this error
_pytest.outcomes.Exit: None of the given test nodes are connectable

from pytest-cloud.

did you resolve the python version issue on all the nodes?

from pytest-cloud.

No. i am yet to resolve that issue.
i have raised a PR, please review and merge

from pytest-cloud.
