Turns out that I needed to have prawn-0.4.1 in the vendor/gem directory.
For some reason the rake command I ran dropped it in root.
vendor/gem/prawn-0.4.1 was not created.
I've fixed by making.. vendor/gem/ and git mv'ing the directory
prawn-0.4.1 to it.
Works now (although I do get a strange error about the gem config file
for prawn being out of date - it offers a solution which doesn't work
either)...
Need to get the hang of these commands, thanks rubyguy!
That shouldn't have worked - the task to unpack gems is rake
gems:unpack. The command you typed just errors out; omitting the
'rake' part would get the results you describe.
To get rid of the warning, run 'rake gems:refresh_specs' on your local
machine (where Prawn is installed). If that still give you the warning
about 'no specification file', let me know.
config.gem: Unpacked gem prawn-0.4.1 in vendor/gems has no specification
file. Run 'rake gems:refresh_specs' to fix this.
rails 2.3.2
ruby 1.8.6 (2008-03-03 patchlevel 114)
there appears to be no .specification file
in vendor/gems/prawn-0.4.1
nor in its system gem directory
