Hi,
I'm trying to make my Rails app auto-install my required gems, by
invoking the gem installation in boot.rb. I'll use the ActionMailer
gem as an example:
...
system "sudo gem install actionmailer --version=1.2.5 -y"
...
Problem is that this fails on the first invocation of Mongrel - it
can't find the gem. However, if I kill and restart mongrel (with the
gem now installed), it works fine.
This problem does NOT occur with webrick, but webrick appears to parse
boot.rb twice when it is started.
Also, if I invoke the rubygems API programatically, not via system,
this problem doesn't occur - but I can't use sudo with this approach.
Any ideas why this happens, or how to work around it?
Below is the output of what happens, from mongrel and webrick.
Thanks,
Chad
