ruby -v
ruby 2.2.6p396 (2016-11-15 revision 56800) [i686-linux]


i have to use passenger for apache. so when i do:
 passenger-install-apache2-module
i have this error:

Unable to autodetect the currently active RVM gem set name. This could
happen if you ran this program using 'sudo' instead of 'rvmsudo'. When
using RVM, you're always supposed to use 'rvmsudo' instead of 'sudo!'.

Please try rerunning this program using 'rvmsudo'. If that doesn't help,
please contact this program's author for support.

with rvmsudo:
rvmsudo passenger-install-apache2-module
-bash: rvmsudo: command not found

i would like to know how to install properly ruby 2.2.6 with root user
through ssh ( i'm using putty ) .
thanks.
