rails-installer.sh runs fine but ruby, irb, rails

Question

I ran rails-installer.sh on ubuntu 12.04. The scripts reports that ruby and gems and rails all installed without problem.

However, when I try:

ruby -v
rails -v
etc.

They all report "command not found".

I am new to linux... what am I missing here?

Answer 1

Arghh.. never mind. sometimes the simple things really do elude me.

The path change do not take effect until you start a new shell.

All is well now.

Answer 2

Just search for every *.bat file inside the C:\RailsInstaller\Ruby2.2.0\bin folder which contains "emachnic" paths, and replace the whole content of them with this code:

@ECHO OFF
IF NOT "%~f0" == "~f0" GOTO :WinNT
ECHO.This version of Ruby has not been built with support for Windows 95/98/Me.
GOTO :EOF
:WinNT
@"%~dp0ruby.exe" "%~dpn0" %*
