Shims are incompatible with `ruby -S` about rbenv HOT 11 CLOSED

Went with the $PATH option since it's far simpler. 2a495dc

I think this problem is back with bundler pre. I am getting:

/models/user_spec.rb
/Users/gnufied/.rbenv/versions/1930/bin/ruby: no Ruby script found in input (LoadError)
rake aborted!

I am running latest version of rbenv with ruby 1.9.3.

from rbenv.

Same error occurs with Ruby 1.9.3 and bundler --pre

from rbenv.

Not to pile on, but I'm having this issue too. Any insight?

% rake spec
...
/Users/artem/.rbenv/versions/1.9.3-p392/bin/ruby: no Ruby script found in input (LoadError)
rake aborted!
/Users/artem/.rbenv/versions/1.9.3-p392/bin/ruby -S rspec ./spec/browser/pagination_spec.rb ...

Which is no wonder (as I understand it) since rspec is a shim, and not a ruby script.

% which rspec

Looks like this should be reopened since #372 seems to have been reverted?

from rbenv.

No, this is not an issue presently even though that PR got reverted. The current Ruby version's bin directory gets pushed onto PATH as soon as you invoke ruby, so in fact the -S flag always has the desired effect.

The difficult problem seems to be allowing shelling out to a different version of Ruby while preserving ruby -S compatibility.

from rbenv.

Well, I hate to break it to you, but this problem seems to have regressed:

That's using (tried and true) Hoe to release one of my gems. It releases fine via system ruby and fails as above when using rbenv. This from rbenv to rbenv, same version. It uses Gem.ruby to specify the full path to the ruby binary. which gem points to the shims directory, but that might be different by the time this comes around via ruby.

Is the above a shell script? What executes it/what generated it?

from rbenv.

The ruby in question is literally: sh Gem.ruby, "-S", "gem", "push", g (where g is the path of the gem to push).

from rbenv.

I just tried to reproduce it with this Rakefile but can't:

task :hey do
  sh Gem.ruby, '-S', 'gem', 'env'
end

What runs the rake task exactly?
