Elements of charm-tools broken under zesty

[Barry Price]

I was specifically interested in 'charm build', but kept getting this traceback regardless of arguments given:

http://pastebin.ubuntu.com/23878542/

On running 'charm help' it looks like many other components are similarly affected, since they can't even run with the --description argument:

To be clear, running Ubuntu 17.04 Zesty Zapus on amd64, package version is from the archive, 2.1.2-0ubuntu4.

I also tried the PPA release, 2.2.0-0ubuntu1~ubuntu17.04.1~ppa2, and found the same issue there.

[Haw Loeung (hloeung)]

Hmm, I saw this as well and even tried this:

| $ python
| ...
| >>> from path import path
| Traceback (most recent call last):
| File "<stdin>", line 1, in <module>
| ImportError: cannot import name path

I copied the path.py module from Trusty and seems to work fine. FYI, the diff looks like this:

[Haw Loeung (hloeung)]

Oh, it's the "Backward-compatibility" bit. "path is deprecated. Use Path instead."

So should be "from path import Path".

It's recommended to use the snap going forward. As we will be removing charm-tools from the archive.

`snap install charm`

The current version of the charm snap does not provide charm-proof[0], so in the meantime I have a temporary ppa with charm-tools 2.2.0 + https://github.com/juju/charm-tools/commit/f820f22e7f11287ff03d5528b1a6ece349c46afa.patch . https://launchpad.net/~freyes/+archive/ubuntu/lp1660004
