Rails "there is no such file to load - rubygems (LoadError)"

I just switched from Heroku to Amazon Web Services. I used to run all Rails command line commands using my Ruby command line (from my Windows PC). However, after I logged into my Amazon Linux EC2 instance and then went into my application directory, I get this error:

/usr/bin/rails:9:in `require': no such file to load -- rubygems (LoadError)
    from /usr/bin/rails:9

when I try to run any commands, for example rails console.

I reviewed this question , but it doesn’t look like several Ruby libraries are applied to me because

which -a ruby

only displays one location:

/usr/bin/ruby

Also, this question did not seem to help, as did I. When I tried to enter text

rvm use 1.9.3

I get this message:

-bash: rvm: command not found
