Hello G.s, ## It seems to need export path of ruby, rubygems Library. This is just Example How to export Path: ## export GEM\_HOME=/usr/local/rubygems/gems export GEM\_PATH=/usr/local/rubygems/gems export RUBYLIB=/usr/local/rubygems/lib export PATH=/usr/local/rubygems/gems/bin:/usr/local/rubygems/bin:$PATH Because I don’t know your server environment. may be its /usr/local/ lib/ruby/ So please confirm and export that should work. Let me know if i can help you. Thanks- Shrii On Feb 2, 12:09 pm, Raimon Fs [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---

Yes, There is relation between that. Please do only: export GEM\_HOME=/usr/local/lib/ruby/gems/1.8 and try again, so that will export another path’s. Thanks- Shrii ---
