rvm is not reading .ruby-version on production server

Question

I have a rails 5.1 app, here is my .ruby-version

ruby-2.5.0

Here is the output of rvm list

rvm rubies

   ruby-2.3.1 [ x86_64 ]
=* ruby-2.4.0 [ x86_64 ]
   ruby-2.5.0 [ x86_64 ]

When I cd to "current" (deployed using Capistrano) I and I run the following:

RAILS_ENV=production bundle exec ruby --version

I get

ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-linux]

I thought .ruby-version was what triggers which ruby version is used. What am I doing wrong?

If you plan on using 2.5..0 as the default ruby version for your app run this on the server

rvm use --default 2.5.0

Its giving you 2.4.0 because its set up as the default and current ie =* means it is what will be used.

Also since you are deploying with capistrano and are using rvm you should consider using this gem.

tried, i get RVM is not a function, selecting rubies with 'rvm use ...' will not work – user1130176 Jan 27 '18 at 15:51
this happens when rvm is not available in the shell did you install rvm as a single user or multi-user? – iamcaleberic Jan 27 '18 at 15:53
don't know, any idea how to fix? – user1130176 Jan 27 '18 at 15:54
@user1130176 check this on how to resolve it if you have any more problems reach out https://stackoverflow.com/questions/9336596/rvm-installation-not-working-rvm-is-not-a-function – iamcaleberic Jan 27 '18 at 15:54
run this `source ~/.rvm/scripts/rvm` the run the `rvm use --default 2.5.0` command tell me how this goes – iamcaleberic Jan 27 '18 at 15:55
```echo "[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"" >> ~/.bashrc``` to fix this permanently – iamcaleberic Jan 27 '18 at 16:02
ok thanks, so just to clarify, .ruby-version does nothing on a production server? – user1130176 Jan 27 '18 at 16:02
in my experience .ruby-version has worked when I changed into the directory on development but on production hasn't been straight forward. – iamcaleberic Jan 27 '18 at 16:04

Per the docs you can set the ruby version explicitly, it also may likely be your server - for instance if you are using nginx you have to explicitly state your path in the nginx config file to your ruby version - but that all depends on your production configuration

https://rvm.io/rubies/default

$ rvm --default use 2.1.1

$ ruby -v

ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-darwin12.0]

Have you installed rvm on the machine? If so make sure it’s in your PATH, what server are you using in production? – alilland Jan 27 '18 at 19:28
