Question

Installed rubyinstaller-1.8.7-p358.exe, then tried to install jammit, but the config.gem command isn’t being recognized. Interestingly I have no file called environment.rb on my drive.

Also I’ve never used ruby 😀

H:\>gem install jammit

H:\>config.gem "jammit"
'config.gem' is not recognized as an internal or external command,
operable program or batch file.

First you need to create a Rails app before you can do:

Add the gem to Rails’ environment.rb inside of the initializer:
config.gem “jammit”

config.gem is not a command rahter it is an entry in the environment.rb file.

To create a rails app go to your source folder and do:

rails new <app_name> # replace <app_name> with whatever you want to call your app

It will create a barebones rails app in a folder with the name that you chose for the app. Inside that folder you will find a config folder and in that folder you will see ‘environment.rb`
