I get same warn too.

Change as following will fix those warn.

@@ -37,8 +37,8 @@ class Pry
     BANNER

     def setup
-      @file = expand_path(target.eval('__FILE__'))
-      @line = target.eval('__LINE__')
+      @file = expand_path(target.source_location[0])
+      @line = target.source_location[1]
       @method = Pry::Method.from_binding(target)
     end

But, Binding#source_location seem like only available on ruby 2.6+

This is already fixed in master 272b3290b

[agargiulo]

It's been fixed but there hasn't been a new release in over a year.

[ogasawaraShinnosuke]

Now, the easiest way is to install the master branch. Aside from being correct or not.

gem specific_install [email protected]:pry/pry.git master

[agargiulo]

I guess a much nicer version of that, which still includes the new fixes but doesn't run the risk of pulling in anything extra would be

# Gemfile
source 'https://rubygems.org'

gem 'pry', git: 'https://github.com/pry/pry.git', ref: '272b3290b5250d28ee82a5ff65aa3b29b825e37b'

This has the advantages of:
1) Being the native Bundler way to install from a github repo
2) Installing a specific git SHA so that you can guarantee consistent gem code between workspaces

[LandonSchropp]

@tonobo Is it possible to get a new release for this please?

[ioquatix]

Looking forward to the next release!

[bsarrazin]

Is a next release scheduled?
