Help getting started

Running windows 8. Uninstalled older version of rails and installed the
most recent version using railsinstaller. Also installed DevKit. When I
do a bundle install, however, I get the following:

c:\RubymineProjects\untitled>bundle install

Any ideas?

I get a basically identical error message.

tc_r · April 23, 2015, 2:43am

Tried just 'gem install json" as well. Still same error messages. Not
sure what to do since I get the same error messages when trying to
install/bundle. Anyone else seen anything similar?

I always recommend not using Windows for Rails, use Mac or Linux (eg
Ubuntu) instead. However since no-one seems able to help you I
googled for
size of array ‘ruby_check_sizeof_voidp’ is negative
which took me straight to

which suggests you may have the wrong version of devkit installed.

It is always worth while googling for error messages.

Don’t understand your comment, the link I posted
(Why does installing Ruby on Rails generate error "size of array 'ruby_check_sizeof_voidp' is negative"? - Stack Overflow)
is answered and the answer has been accepted by the OP as correct.

Colin is right about switching to Mac or Linux. If you really want to
use
Ruby & Rails, setup up a VM in VirtualBox. I use Linux Mint which is
great
for traditional Windows users. Be fearless and jump right in. Google
Search
is your friend.
