Hi everyone

I want to install ferret on windows. I run the command ‘gem install
ferret’, but I got this error.

Building native extensions. This could take a while…
ERROR: Error installing ferret:

.6 for inspection.

It works with rubyinstaler.org 1.8.7 and DevKit. Fails on 1.9.2.

Devise compiles and installs with 1.9.2 and 1.8.7

I doubt you’ll be able to find pre-compiled binaries for every gem you
want to use. If you want to keep developing on Windows, and I’ll spare
you the commentary, you’ll need to get a C compiler set up. I’ve read
about using the free version of Visual Studio, but searching Google for
“compile ruby extensions windows” returned plenty of instruction.
