Can I specify ruby version with patchlevel in Gemfile?

Question

Bundler documentation for version 1.5 says that I should specify patchlevel as follows:

ruby '1.9.3', :patchlevel => 448

When I follow the instruction and run bundle install, I get:

The Ruby patchlevel in your Gemfile must be a string

If I do

ruby '2.0.0', :patchlevel => '353'

Bundler says:

ruby-2.0.0,:patchlevel=>353 is not installed.
To install do: 'rvm install ruby-2.0.0,:patchlevel=>353'

Is it even possible to specify ruby version with patchlevel in Gemfile?

have you tried running `rvm install ruby-2.0.0,:patchlevel=>353` like it says? — Raj, Mar 18 '14 at 11:40
No, as there is no such version `ruby-2.0.0,:patchlevel=>353`. — Ivan Zamylin, Mar 18 '14 at 13:26
That patch might be requiring a specific version of ruby , first install it and then include it in Gemfile . — Caffeine Coder, Mar 18 '14 at 13:41
I have ruby-2.0.0-p353. It is current and default. The problem is that `bundler` is looking for `ruby-2.0.0,:patchlevel=>353` which looks like a bug. — Ivan Zamylin, Mar 18 '14 at 13:58
No, but I would like `bundler` to select ruby version the way Heroku does. — Ivan Zamylin, Mar 18 '14 at 14:09
I can only suggest: update or reinstall bundler. This does seem like a bundler issue. — Magnuss, Mar 18 '14 at 14:16
`gem update bundler` (update from 1.5 to 1.6.2) did the trick. Patchlevel however has to be a string. — Greg, Apr 26 '14 at 21:54

rvm install 2.0.0-p353 at the command line (in your shell) will do it for you.

You can specify the Ruby version in the Gemfile (Heroku does this) and it is OK, but it will only report, not install, the version problem.

So you would then have in your Gemfile:

ruby '2.0.0', :patchlevel => '353'

That will help RVM to determine which version of Ruby you should use.

You don't install ruby with bundler. Use RVM for that. It is used to specify a dependency on a specific ruby version/patchlevel.

I have ruby. I need `ruby '2.0.0', :patchlevel => '353'` statement in `Gemfile` to select ruby version in production. – Ivan Zamylin Mar 18 '14 at 13:13
When you do `rvm list` does it contain `ruby-2.0.0-p353`? – Magnuss Mar 18 '14 at 13:37
Here is the output of `rvm list`: `=* ruby-2.0.0-p353 [ x86_64 ]` – Ivan Zamylin Mar 18 '14 at 13:59
