Problem using Zero-Deploy

[Nicholas Lippis]

I am evaluating using zero-deploy for a project I am working on and I have been hitting an issue.

Whenever I try to run the server = DeployedServer(mach) command in the python interpreter I get an error specifying that there is no such module as rpyc.utils.server.  I have run this command on two linux devices, one being a polky linux based server and another running standard Ubuntu 12.04 LTS and received the same result. Sample output is provided below.

Python 2.7.3 (default, Sep 26 2013, 20:03:06)

[GCC 4.6.3] on linux2

Type "help", "copyright", "credits" or "license" for more information.

>>>

>>> from rpyc.utils.zerodeploy import DeployedServer

>>> from plumbum import SshMachine

>>> mach = SshMachine("192.168.1.10","user")

>>> server = DeployedServer(mach)

Exit code: 1

         | ImportError: No module named rpyc.utils.server

This makes sense, as I had not installed it previously; but I was under the impression that Zero - Deploy will copy the local (client’s) copy of rpyc into the temporary directory created by plumbum, which must not have happened.

I tried running the commands again after I installed rpyc on the remote server and everything worked very well, so I am convinced that there is an issue with copying rpyc over.

Any suggestions?

I'm guessing it is trying to import from the pythonpath, which doesn't include the temp directory (which is why installing rpyc on the remote server fixed the issue). Check your deployed-rpyc.py file to make sure that it's setting the python path to that location first (sys.path.insert(0, here)).
