Pry running with obsolete Ruby version

Question

When I type pry -v I get

Pry version 0.12.2 on Ruby 2.3.0

whereas ruby -v gives

ruby 2.6.0rc2 (2018-12-15 trunk 66408) [x86_64-linux]

and rbenv global and rbenv local both give

2.6.0-rc2.

I tried uninstalling and reinstalling pry as suggested in an answer to how to change ruby version in Pry.

If your system supports it, which pry for one will tell you where pry is coming from. You may want to gem install pry. — tadman

which pry points to a bash script at ~/.rbenv/shims/pry. Pry should be taking its cues from rbenv. — Lori

You can have pry installed as a global executable, from the system ruby. This won't be overridden by any ruby installed by rbenv, unless the pry gem is installed in that specific ruby version.

It's just a matter of the system searching $PATH for an executable file called pry.

Most probably, if you gem install pry under rbenv, then the new pry will use the correct ruby binary.

EDIT:

Whops, @tadman's comment has exactly the same content. If it is converted to an answer I will delete mine.

Interesting. gem install pry worked this time. Can't think of anything I did differently from last time, except for not uninstalling before reinstalling.

This is a much longer explanation than mine, so it's all good.
