Unable to install rails

Hello all,
I am stuck and I need your help. I tried to install rails and got the
mkmf error. I installed ruby1.8-dev and I am still getting the same
error.

Rails install error:

[email protected]:~# gem install rails
Building native extensions. This could take a while…
ERROR: Error installing rails:
ERROR: Failed to build gem native extension.

Gem files will remain installed in /var/lib/gems/1.9.1/gems/json-1.6.4

Have you tried installing rvm?

It may not be easy but it will handle your ruby versions (that seems to
be
the problem)

I just did that and it resolve the issues. Thanks.

Try using Sudo

Also, Xcode could be out of date re: this problem (

Does railsready use RVM? I’ve followed the RVM instructions on a
couple machines and never had any problems installing RoR on a Mac.

From a quick look at the link, it also gives you Homebrew (not a good
idea
if have MacPorts/fink installed) & it is recommended to run it on a
fresh
install of the OS. There is an rvm option.

Bit over the top for my liking…

Cheers,

Nothing to see here… move along, move along

The error message refer version 1.9.1

I suggest install version 1.9.2 using rvm.
