feedzirra windows latest curb version issue - ruby-on-rails

Question

I am trying to install feedzirra but I am running into trouble.
When I install Feedzirra, it looks for curb (0.7.18).
I followed the instructions to install curb on windows
>gem install curb -- --with-curl-lib=C:/curl-7.27.0-devel-mingw
32/bin --with-curl-include=C:/curl-7.27.0-devel-mingw32/include
Fetching: curb-0.8.4.gem (100%)
Temporarily enhancing PATH to include DevKit...
Building native extensions with: '--with-curl-lib=C:/curl-7.27.0-devel-mingw32/b
in --with-curl-include=C:/curl-7.27.0-devel-mingw32/include'
This could take a while...
Successfully installed curb-0.8.4
Installing ri documentation for curb-0.8.4

I tried to uninstall and reinstall feedzirra, it did not help as I get the following message
Installing curb (0.7.18)
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension

An error occurred while installing curb (0.7.18), and Bundler cannot continue.
Make sure that `gem install curb -v '0.7.18'` succeeds before bundling.
How do I force feedzirra to use the latest version of curb? or How to install curb (0.7.18) version only?

Answer 1

Try to add -v 0.7.18 after gem install curb:
>gem install curb -v 0.7.18 -- --with-curl-lib=C:/curl-7.27.0-devel-mingw32/bin --with-curl-include=C:/curl-7.27.0-devel-mingw32/include
The latest Feedzirra has a curb ~> 0.7.15 as a dependency, so curb-0.8.4 won't be suitable - here is an explanation referring to the bundler site.
Also if you're using something like RVM (if I remember correctly there's a nearly similar utility for windows called pik) then ensure that you're installing gems to the gemset used by your application.
