I am tryng to install ruby on rails in centos server on AWS. I can't install rails on the server. It is giving some error. Here is what I am getting while installing rails.

#gem install rails
   ERROR:  Error installing rails:
    gzip error installing /usr/local/lib/ruby/gems/1.8/cache/activesupport-3.0.8.gem

  1. Make sure you have Ruby 1.9.2 installed. Rails 3 requires Ruby 1.8.7 or 1.9.2. Ruby-1.9.2 has a better performance.
  2. Use "file" to determine the type of the 'gem' file you downloaded
  3. If possible, use 'rvm' to install and manage Ruby, Rails and other gems. Warning: compilation on AWS is slow.

Install zlib-devel package on S.O. and recompile your ruby version

ok, this is ancient, but I think still relevant.

the output you pasted does not clearly state the error, but my feeling is that you hit a permission error.

I am making these assumptions: - your ruby is installed as system package - your GEM_ROOT is /usr/local/lib/ruby/gems/ - you run the gem install command as a regular user.

you can give write access to your GEM_ROOT folder to a specific user group and have your unix user be part of one group. or like most people do, use sudo.

although I recommend against install ruby via system package and gems as root. you will endup compiling C code by root which is not recommended.

you should have your web user install rvm, this way you can have multiple ruby installed under his home directly. gems will instead more easily too.

then you configure your apache/nginx to point to those directories

Define RVM_ROOT /usr/local/rvm/gems
