尝试在Ruby on Rails上使用时出错

Question

It's supposed that I installed Ruby on Rails using RailsInstaller (Windows), but when I try to use the command:

rails -v

The command prompt shows something like:

"System can not find the specified path."

I've uninstalled Rails with 'gem' command and reinstall it, but error still alive.

Is there another way to install Ruby on Rails? How can I solve this problem?

NOTE: Ruby\\bin is in PATH variable.

Answer 1

I found a solution: installing the previous version of RailsInstaller.

I was trying to use: railsinstaller-3.2.0 (Ruby 2.2.4, Rails 4.2)

It worked good with: railsinstaller-3.1.1 (Ruby 2.1.8, Rails 4.2)

NOTE: I'm using W7 OS.

Check out the answer on this one. You have to add rails to path.
