Hi I have just started reading Ruby On Rails For Dummies and once I  
installed ruby184-20.exe I was told to enter the following cmd line:  
gem install rails -r -y

There is a screenshot in the book of how the installation should look  
like in the cmd window and the last successful installation is this:  
Installing RDoc documentation for actionpack-1.13.5…

Afet that line it then says:  
lib/action\_controller/routing.rb:1089:30 ‘:’ not followed by identified  
or operator  
lib/action\_controller/routing.rb:1093:39 ‘:’ not followed by identified  
or operator

Those two lines dont appear in the books screenshot. Will this cause me  
any problems or will i be ok? Is there a fix?

That’s likely just RDoc (the documentation generator for Ruby)  
complaining about some weird markup thing. I wouldn’t worry about it.
