Debuild issues

[willkelly]

I got the following via email. I'm making this issue and letting the user know to check back here in case there are questions or solutions.

• I found the package manager, ZPM, but wasn't able to get it running. Is this
  supposed to be usable, or am I doing something funky? I first tried the
  instructions in the README, but debuild failed (see below). I then installed
  the zpm python package with python setup.py install, but running zpm bundle
  to build my test ZAR fails with a jinja template error (also below).

  In case it is helpful, here is the debuild failure (this is on ubuntu 12.04):

Thanks for reporting this! I haven't looked into why building the Debian package fails. However, I would suggest not bothering with a Debian package at all and instead installing ZPM into a virtual Python environment:

$ virtualenv zpm-venv
$ source zpm/venv/bin/activate
$ pip install .

This will give you a self-contained installation inside the zpm-venv directory. You find the zpm script as zpm-venv/bin/zpm and you can then symlink it into a more convenient place on your PATH.

This bug report tells me that the readme is misleading. It seems to imply that running the packaging steps is necessary in order to install zpm, which is not true. I will amend the readme to make it a little more clear.

For the moment, the best way to install is to use pip install git+[repo url], or clone and run python setup.py install. I'll fix up the readme to add these instructions.
