Very helpful tutorials. Just follow step by step. Now my ruby version is 1.9.3.

when I run gem install rails, then I got the error
ERROR: Error installing rails:
mime-types-data requires Ruby version >= 2.0.
my ruby version is ruby 1.9.3p327 (2012-11-10 revision 37606) [x86_64-linux]
Same issue a @daemonchen
[root@localhost ~]# ruby -v
ruby 1.9.3p551 (2014-11-13 revision 48407) [x86_64-linux]
[root@localhost ~]# gem --version
2.6.4
[root@localhost ~]# gem install tins
ERROR: Error installing tins:
tins requires Ruby version >= 2.0.
@manusreload, you need to
rvm <version here> --default OR rvm use <version here> --default
not sure what works
but worked for me
Awesome..so crystal clear steps and works like a gem..tons of thanks..
👍
This is great!
This is clever, but there's a much better way that works much better with CentOS: Software collections. Consider this as an alternative to what's basically an OS-uncontrolled source compile on your system: https://www.softwarecollections.org/en/scls/?search=ruby
Lovely tutorial for this. Has been mentioned before, but I needed to change source /etc/profile.d/rvm.sh to source ~/.profile apart from that though, very good!
Thanks! - so much helpful
