Ruby on rails 4

Question

Hi, I tried to upgrade to ruby on rails 4 but it fails.

I move into my rails app generated by webfaction installer script and I run this commands:

export GEM_HOME=$PWD/gems
export RUBYLIB=$PWD/lib
export PATH=$PWD/bin:$PATH

In this way I try to install the gems locally instead of trying to install it where I don't have permissions to.

Then I run:

gem install rails --version 4.0.0rc2

and I get this:

Building native extensions.  This could take a while...
ERROR:  Error installing rails:
    ERROR: Failed to build gem native extension.

    /usr/local/bin/ruby2.0 extconf.rb

This appears to be a problem with the Ruby 2.0 installation on our CentOS5 servers.

I'm not sure when it will be feasible to fix it, since it will require an update to glibc, which could break a lot of other things on the server.

If you need to update to Rails 4 immediately, then my recommendation is that you migrate your account to one of our CentOS6 servers, where we've verified that the problem does not exist.

Hi, thank you so much. I am using WebFaction since a few years and I am always very satisfied!

I asked for the migration. In case I face problems I will write in this conversation.
