rails console throws "uninitialized constant Pry::Prompt (NameError)"

[enwood]

Hi,
I'm getting this error when launching the Rails console in a Rails 4.2.6 project that's using:
pry 0.9.12.6
pry-byebug 1.3.2
pry-rails 0.3.5
pry-rescue 1.4.5

Bundle complete! 78 Gemfile dependencies, 162 gems now installed.
Use bundle show [gemname] to see where a bundled gem is installed.

If I remove pry-rails, I have no trouble launching the console:

Use `bundle show [gemname]` to see where a bundled gem is installed.
~/Sites/crs  (rails_4_2 *) % bundle exec rails c
Loading development environment (Rails 4.2.6)
[1] pry(main)> 

Any ideas?

Gemfile:

gem 'pry'
gem 'pry-byebug'
gem 'pry-rails'

That's a pretty old version of Pry. Could you try running bundle update pry pry-byebug pry-rails pry-rescue and see if you can bring them all forward?

Hah, hah! Thanks, Ryan. That did the trick. Moved up to

Using pry 0.10.4
Using pry-byebug 3.4.2
Using pry-rails 0.3.6
Using pry-rescue 1.4.5

and all is well.

Thanks so much,
Tim

No problem!

You might first need to do bundle add pry-rails and then bundle add pry-rescue before running that command.
