Hello,
I'm trying to get a ruby script run into a crontab and it keeps failing
saying it can't find my mechanize gem. When I run the script form the
command line, everything runs fine and I don't get any failures.
Anyone ever had that problem before?

Make sure you have this ENV variables pointing to the correct dirs:
GEM_HOME=/usr/local/rubygems/gems
GEM_PATH=/usr/local/rubygems/gems
RUBYLIB=/usr/local/rubygems/lib/ruby/site_ruby/1.8

Often and often when cron jobs fail it is because the environment variables
are not set. Cron jobs do not automatically execute .bashrc (or equivalent)
you generally need to create a script that calls your program after either
setting the environment by hand or doing eg ". .bashrc".

Oh yes.
Try getting it to run from the command line with a blank
environment with 'env -', e.g.,
% env - run_stuff.sh
Typically a crontab job runs with a much reduced environment.
Alternatively, stick a printenv in your crontab to see
what environment it is working with and compare to your
interactive environment.
You might also find crontab's sister command, 'at', helpful
to get tighter feedback cycles.

Hi,
If I start by a human-written block of data, such as ITEMS below, is it possible to deserialize these into objects of type Item? How might this be done?
Thanks for any help,
James
ITEMS = %q{
---
item:
- name: blah
- type: blah
- location: blah
}
class Item
attr_accessor :name
attr_accessor :type
attr_accessor :location
def initialize
@name = ""
@type = ""
@location = ""
end
end
Hmm I've tried running with a blank environment and it fails with the
same error not finding the gems. I have set the ENV variables to the
proper directories and it is still giving me the same error. I'm not
sure what else to try although I appreciate all your recommendations!

Set them *where*? You need to set them in your crontab directly,
*not* in your personal e.g. .bashrc.

Easy, just yaml them to find out how the serialized form should look:
class Item
attr_accessor :name
attr_accessor :type
attr_accessor :location
def initialize
@name = ""
@type = ""
@location = ""
end
end
require 'yaml'
y Item.new
If you run this you get:
--- !ruby/object:Item
location: ""
name: ""
type: ""
Then you can play with the string and check that YAML.load does the right thing on this data

From (recent) experience here, I've had similar issues across
different versions of the same distro (CentOS/RedHat). The paths and
environment variables are drastically different. For me, I was
shelling out to lspci
Something along the lines of this would have been a valid fix.

Force of habit; in this example, no, but if a subsequent part of the
entry spawns a new shell, I think it's necessary.
I think. Will have to revisit that sometime, but not today

Tried everything in here and same problem. What I've noticed though this
version of Ubuntu (Feisty Fawn 7.04) which I know is outdated messed up
all the paths for ruby and rubygems.

Shouldn't matter if you put in full paths to everything you reference.

Hey, does this thread have anything to do with the Bourne-shell usage bias which first manifested itself for me in at last year? In other words, if you use a shell, any shell, in at you get sh, not bash, the former being considered lighter weight and perhaps somehow safer and more standard, but on the other hand breaks things like some commands you are used to in some syntax in Bash. For instance, you must do the following to export:
x=y
export x
because export x=y does not work in sh. ???

Maybe if you post the actual crontab entry that you're having trouble
with, we'd have a chance of finding the specific problem
