How do I fix rvmrc file? - ruby-on-rails

Question

I set up rvm (and .rvmrc file) not properly, therefore whenever I go the directory of my RoR project and type rails s or any other rails command, I'll get the error of
The program 'rails' can be found in the following packages:
* rails
* ruby-railties-3.2
Try: sudo apt-get install <selected package>
and I have to type rvm use 1.9.3-p392 to fix it.
.rvmrc file contains
environment_id="ruby-1.9.3-p392#project1"
if [[ -d "${rvm_path:-$HOME/.rvm}/environments"
&& -s "${rvm_path:-$HOME/.rvm}/environments/$environment_id" ]]
then
\. "${rvm_path:-$HOME/.rvm}/environments/$environment_id"
for __hook in "${rvm_path:-$HOME/.rvm}/hooks/after_use"*
do
if [[ -f "${__hook}" && -x "${__hook}" && -s "${__hook}" ]]
then \. "${__hook}" || true
fi
done
unset __hook
else
# If the environment file has not yet been created, use the RVM CLI to select.
rvm --create "$environment_id" || {
echo "Failed to create RVM environment '${environment_id}'."
return 1
}
fi

Answer 1

Try
rvm use ruby-1.9.3-p391 --default

Answer 2

.rvmrc in the newest version of RVM is deprecated. It should work but try new syntax:
put to .ruby-version file just:
1.9.3-p392
Additionaly you can define .ruby-gemset with
yourgemsetname

Post your rvmrc file in order to get some help.
If you want to check a look at other's project rvmrc file you can take a look at octopress here. Also you can take a look at rvmrc docs if you haven't already looked.
The message you've got is from the autocomplete ubuntu/debian projects, meaning that it can't found the rails command, so it suggests the packages you can install to get it.
Probably you havent loaded the rvm environment. You can load it via:
source $HOME/.rvm/scripts/rvm
and then check if it works.
