I have been trying to understand RVM and decided to do so by not using it and seeing the consequences. I am trying to see how I can manage different versions of ruby and their gemsets without RVM.
I compiled Ruby 1.9.1 from source on my Ubuntu machine and found it in the path usr/local/bin/ruby.
So I was making a cgi ruby script and had the following at the top of the script file:
#!/usr/bin/env ruby
require 'rubygems'
require 'action_pack'
require 'cgi'
After a couple of hours of not getting "/usr/bin/env: ruby: No such file or directory" error and google searching, I uninstalled my system ruby 1.8.7 (I also had 1.9.3 installed via rvm) by doing sudo apt-get purge ruby rubygems.
I'll let the shell log explain itself:
root:~# rvm current
system
root:~# which ruby
/usr/bin/ruby
root:~# rvm use 1.9.2
Using /root/.rvm/gems/ruby-1.9.2-p290
root:~# rvm current
ruby-1.9.2-p290
root:~# which ruby
/root/.rvm/rubies/ruby-1.9.2-p290/bin/ruby
root:~# rvm system
root:~# rvm current
system
root:~# which ruby
/root/.rvm/rubies/ruby-1.9.2-p290/bin/ruby
root:~#
At this point, if rvm cl
Hi,
I am a php developer and I decided to learn ruby on rails.
I have a few question.
I have an ubuntu virtual machine with lamp.
It mean that it has alrweady php and when I access the ip of the machine from my browser it does load the index.php.
if I install ruby on rails will theere be collision between the php and ruby or the server just know that if I ask for ruby file or for php.
I have NGiNX setup, and would like to be able to run sites I create in Ruby.
However my server is pretty fail, only like 250mb memory, probably less, so instead of having to run each Ruby site with the Thin server I want to run the Ruby sites only when they are accessed, like the way PHP works with the PHP-FPM server.
How does one go about this with NGiNX and Ruby?
which -a ruby gives me
/usr/ruby
/usr/ruby
/usr/ruby
It gives the same path three times. Why does this happen?
today, I was installing ruby from compiling, and I followed instructions to use the sudo command, but I ended up with some folder permission issues.
I am using Ubuntu 12.04 64 bits.
