Linux Compatibility

[elliottomlinson]

Apparently the product of disparity between the handling of temp files on ubuntu vs. osx, we run into a 'No such file or directory' issue when generating cards on Linux.

For reference, the installation process has looked like this so far (followed by a shell restart):

and an edit to the first line of the exe, changing

1. #!/usr/bin/env ruby --disable-gems

to

1. #!/usr/bin/env ruby

Suspecting this had something to do with my ruby installation, I've tried the following (each from a fresh install of ubuntu):

• using rbenv instead of rvm
• using a conventional install of the current ruby with apm
• using a conventional install of the current ruby with snap
• using chruby to change versions from a normal install

to be met with the same error each time - giving me the confidence to assert that it's emergent from a discrepancy between mktmpdir on osx and ubuntu.

In case it matters I'm now using rbenv (once again from a fresh install).

Now that @elliottomlinson has this working on his Windows machine, I'm going to de-escalate this from "Bug" to "Enhancement", since we don't really need it.
