Your version of DataMapper is really old (current version is 1.1 with 1.1.1 being just around the corner). If it's an option for you, try upgrading and the problem will be gone. However, it's only fair to note that an upgrade from 0.9.2 to 1.1 probably won't go without at least some breakage. The various release notes in between should cover the changes you need to make tho.

In general, and iirc, Pathname#/ was provided by extlib so you could start out by grepping that source for the exact file to require. I'd be surprised if DM-1.1 still suffers from that problem (the dependency on extlib has been removed).

I'm closing this issue now. In general, please file DM issues (for the latest version) at http://datamapper.lighthouseapp.com/projects/20609-datamapper

bizarre, that gem versioning is what I got from bundler install of a project Gemfile generated by Padrino... go figure.
Thanks.

It should be noted that the "data_mapper" gem is ver 0.9.2 while the "datamapper" is the current one.

That said, the official DataMapper documentation says to use "data_mapper" which is clearly incorrect:

http://datamapper.org/getting-started

Just thought I'd point that out.

I have this issue with data_mapper ver. 1.1.0

I've just also been fooled by the data_mapper =/= datamapper thing ; could someone correct the ?

Thanks in advance.

[solnic]

Actually no, both gems are the same and there are 2 because of historical reasons heh. We will remove datamapper gem soon. So people should be using data_mapper.
