Solved Error installing rails: i18n requires Ruby version >= 1.9.3

I was trying to install rails on CentOS operating system, I got the error Error installing rails: i18n requires Ruby version >= 1.9.3.

Solution: Update the Rails Version


Execute following commands:



yum groupinstall -y development
curl -L get.rvm.io | bash -s stable
 
  
Error installing rails: i18n requires Ruby version >= 1.9.3
I again received following error: GPG signature verification failed for '/usr/local/rvm/archives/rvm-1. 

To solve it curl -sSL https://rvm.io/mpapis.asc | gpg2 --import - in terminal

 
gpg: key D39DC0E3: public key "Michal Papis (RVM signing) <mpapis@gmail.com>" imported
gpg: Total number processed: 1
gpg:               imported: 1  (RSA: 1)

-------------------------------
Run the following command again curl -L get.rvm.io | bash -s stable
It will install RVM to /usr/local/rvm/
 
Once execution in successfully completed, execute following command in Terminal:
 
source /etc/profile.d/rvm.sh
rvm install 1.9.3  

If you get following Error:

GPG key retrieval failed: [Errno 14] 
Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag 
 
Run following command in terminal:
rpm –import http://apt.sw.be/RPM-GPG-KEY.dag.txt
  
Now, once all errors are solved run following command again:
 
rvm install 1.9.3  
 
Now check the ruby version by running below command:
 
ruby --version 
 
DONE!
