ERROR installing documentation while gem install rails (Win7 Rails 1.9.3)

Rails
1

Using Windows 7 Professional
Loaded Ruby v1.9.3p545 (2014-02-24) [i386-mingw32]
Installed dev kit (C:/Ruby193/lib/ruby/site_ruby/devkit.rb)

Tried to install rails at this point with “gem install rails”. Process
died and received the following error while installing docs:

ERROR: While generating documentation for actionpack-4.1.1
… MESSAGE: Invalid argument -
./ActionDispatch/Routing/Mapper/Scoping/:
… RDOC args: --ri --op
C:/Ruby193/lib/ruby/gems/1.9.1/doc/actionpack-4.1.1/ri lib --title
actionpack-4.1.1 Documentation --quiet

I figure I can live without documentation, but this is a problem and I
am
wondering if anyone has resolved this issue?

I have run into the same issue. Different from the OP, I am new to Rails
so probably cannot live so well without documentation.

Has anybody else run into this and found a solution?

You may well find it difficult to get help with problems on Windows as
most developers use Linux (eg Ubuntu) or Mac. I suggest either set
you machine to dual boot with, for example, Ubuntu and start again.
Alternatively you can run linux in a virtual machine inside windows
using vmware or virtualbox.

Then I advise using rvm for installing ruby and rails, others like
rbenv I believe.

If you really must use Windows then I understand railsinstaller is the
preferred route.

gem clean " or some new versions " gem cleanup" that will clear everything
left including bundle and anything else you installed using gems. So after
installing them back you can proceed to using the command " gem install
ruby --pre ". If by some chance you do get the same error, dont worry, type
in this final command " gem install ruby -v 4.1.1 " this one will start off
fast because it is skipping over the stuff already installed correctly and
then it will be on getting the documents for a wail. Just be patient and
when you finally see “1 gem installed” lol you are riding ruby on rails!
Hope this helps :slight_smile:
