when i try to install activerecord gem on ironruby, i’ve got:

> igem install activerecord -r --no-rdoc --no-ri  
> ERROR: Error installing activerecord:  
> activesupport requires Ruby version \>= 1.8.7

(‘ir.exe -e “puts RUBY\_VERSION”’ returns ‘1.8.6’)

may be i can change ruby version in igem to 1.9.1?  
or there is another way?

I ran previously with the same problem, add the version that works.

try:

> igem install activerecord -v 2.3.8 --no-rdoc --no-ri

i can run “ir.exe -1.9” and RUBY\_VERSION will be 1.9.1  
but by default (and in “igem” RUBY\_VERSION is 1.8.6 by default.  
perhaps there is a way to set ruby version for “igem” (and for “iirb”)  
or change running default arguments?

Right, if you use the current binaries (1.0 or 1.1) the compatibility is  
with MRI 1.8.6.  
If you build the latest source from GIT repo you’ll get 1.9.2 compatible  
IronRuby.

As I understand it, Ruby 1.9 compat in IronRuby 1.0 and 1.1 was not all  
that  
complete. So, even if you force them into 1.9 mode, things may break in  
unexpected ways, and you’ll probably just get frustrated. YMMV.

As Tomas said, if you want better 1.9 support, grab the latest from  
GitHub:  
[http://github.com/ironruby/ironruby](http://github.com/ironruby/ironruby) and build it:  
[http://github.com/ironruby/ironruby/wiki/Building](http://github.com/ironruby/ironruby/wiki/Building)

If you run into an issue, the best way to get a response is going to be  
to  
create a failing test for it, and submit it as an issue, or vote up an  
existing issue if it has already been reported, on the CodePlex site:  
[http://ironruby.codeplex.com/workitem/list/basic?ProjectName=ironruby](http://ironruby.codeplex.com/workitem/list/basic?ProjectName=ironruby)
