My first time out; I’m reading Michael Hartl’s book, and installing according to the instructions on [Rubyonrails.org](http://Rubyonrails.org).

Everything fine until the end of the command “gem install rails”. The last three lines of the installation report on screen were:

Installing ri documentation for actionpack-4.1.4…

ERROR: While generating documentation for actionpack-4.1.4

… MESSAGE: Invalid argument - ./ActionDispatch/Routing/Mapper/Scoping/:

… RDOC args: --ri --op C:/Ruby193/lib/ruby/gems/1.9.1/doc/actionpack-4.1.4/ri lib --title actionpack-4.1.4 Documentation --quiet

Cheers,

Does it say that the install instructions are for Windows and for rails 4.1?. You have not provided a specific link so I am not able to check. If they are not specifically for Windows then they are unlikely to work.

We will have someone look at that. Can you also open a ticket on GitHub? We usually track the bug progress overthere. (If you mention me @sikachu on that that’d be great as well).

In the meantime, you should be able to do `gem install rails --no-ri --no-rdoc` which skips the local documentation generation.

Thanks!
