ERROR: Error installing ffi: ERROR: Failed to build gem native extension

Question

Got the DevKit installed and re-ran the ffi install….got this as an output:

C:\\Documents and Settings\\******>gem install ffi
Temporarily enhancing PATH          


        

Answer 1

For me the fix was running in this order. I'm not sure what all was relevant, but it worked:

gem install ffi --version '1.0.9'

The above failed, but then I could successfully run:

gem install bundler

...and subsequently:

gem install ffi

...which got the latest version (1.6.0 at the time of writing this) and installed it successfully.
