ruby - Can't declare variables in Powershell -



ruby - Can't declare variables in Powershell -

i next along larn ruby hard way book , having problem powershell. have gotten ruby running in shell , can perform calculations , run .rb files. however, when seek simple variable assignment such as:

i = 4

i big reddish error message saying along lines of "i : term 'i' not recognized name of cmdlet, function, script file, or operable programme etc..."

why trying read script/program name instead of variable assignment?

using ruby 2.0.0p576 (x64) on 64 bit windows 8 machine if helps @ all.

i realized won't allow me basic comparisons 4 == 9. tries read assignment reason.

did seek irb command ? calculations , mimics need run irb first.

ruby variables declaration
