Juggernaut problems

Ruby
1

Hi All,

I am new at RoR, I am trying to do “gem install juggernaut”, this
requires json and event machine. I have successfully installed event
machine, but when I am trying to install juggernaut or json, this is
happening:

C:\Users\aabraham>gem install juggernaut
Install required dependency json? [Yn] Y
Building native extensions. This could take a while…
ERROR: While executing gem … (Gem::Installer::ExtensionBuildError)
ERROR: Failed to build gem native extension.

ruby extconf.rb install juggernaut
creating Makefile

nmake
‘nmake’ is not recognized as an internal or external command,
operable program or batch file.

Gem files will remain installed in D:/RubyNew/ruby/lib/ruby/gems/1.8/
gems/json-1
.1.3 for inspection.
Results logged to D:/RubyNew/ruby/lib/ruby/gems/1.8/gems/json-1.1.3/
ext/json/ext
/parser/gem_make.out

Can someone please help me on this?

You need to install nmake for windows… I am a linux guy and wouldn’t
know how to help you on windows but I am sure you can find an install
for it somewhere…

once nmake is in your path, you will be set to go (if you have the libs
that that json is attempting to bind with)

nmake
‘nmake’ is not recognized as an internal or external command,
operable program or batch file.
JSON for some reason doesn’t have a binary executable available for
download, and anticipates you having a compiler available.

You could try installing MSVC 6 [and having it in your path] or try a
mingw version of Ruby, and also install its devkit:

YMMV.
