Hello… I am trying to install a Ruby application called Redmine. In order to create database structure, I have to execute this command: rake db:migrate When I run it, a message telling that msvcrt-ruby18.dll was not found (I’m attaching the complete message). I have downloaded the last ruby version (1.9.1) and when I install it, it automatically installed rake 0.8.7. Since I have msvcrt-ruby191.dll, why rake is trying to load the wrong DLL? This is the environment setting: RubyGems Environment: - RUBYGEMS VERSION: 1.3.6 - RUBY VERSION: 1.9.1 (2010-01-10 patchlevel 378) [i386-mingw32] - INSTALLATION DIRECTORY: C:/Ruby19/lib/ruby/gems/1.9.1 - RUBY EXECUTABLE: C:/Ruby19/bin/ruby.exe - EXECUTABLE DIRECTORY: C:/Ruby19/bin - RUBYGEMS PLATFORMS: - ruby - x86-mingw32 - GEM PATHS: - C:/Ruby19/lib/ruby/gems/1.9.1 - C:/Documents and Settings/Administrator/.gem/ruby/1.9.1 - GEM CONFIGURATION: - :update\_sources =\> true - :verbose =\> true - :benchmark =\> false - :backtrace =\> false - :bulk\_threshold =\> 1000 - REMOTE SOURCES: - [http://rubygems.org/](http://rubygems.org/) And these are the gems that were installed automatically: \*\*\* LOCAL GEMS \*\*\* actionmailer (2.3.5) actionpack (2.3.5) activerecord (2.3.5) activeresource (2.3.5) activesupport (2.3.5) mysql (2.8.1) rack (1.0.1) rails (2.3.5) rake (0.8.7) rmagick (2.12.0) rubygems-update (1.3.6) Any help will be greatly appreciated Thanks Jaime ---

This means “you’re running some gem or other that has binaries for 1.8 but not 1.9” what’s your backtrace? (rake --trace I think). -rp ---

The backtrace I even more desire would be $ rake db:migrate --trace My first guess is a bad mysql gem [?] but the backtrace will tell us better. -rp ---

Rake do not depend directly of Ruby runtime library either for 1.8 or 1.9, as is pure ruby. What you might be experiencing is a gem that your application depends on that do not provide binaries for Ruby 1.9, the version fo Ruby you’re running. Please provide the output of “rake db:migrate --trace” from inside your application folder and not your home/profile directory as you executed in response to Roger comments. > ``` > - x86-mingw32 > -http://rubygems.org/ > > ``` > > mysql (2.8.1) > rack (1.0.1) > rails (2.3.5) > rake (0.8.7) > rmagick (2.12.0) > rubygems-update (1.3.6) My guess will be around rmagick gem, as I’m unaware of it being distributed as fat-binaries and even less for Ruby 1.9 support. Since you’re running Ruby from RubyInstaller, those are my assumptions, but I might be wrong.
