Bundler | Ruby#

Error Could not find gem ‘pry-doc#

Consider this Gemfile:

source 'https://rubygems.org'

gem 'pry'
gem 'pry-doc'

In the past (IIRC), we could run both bundler or bundle commands interchangeably:

$ bundler install
$ bundle install

This is what I see on Jul 2022 with ruby 3.0.0 (installed through rvm) on my Arch Linux system:

$ ruby --version
ruby 3.0.0p0 (2020-12-25 revision 95aff21468) [x86_64-linux]

$ bundler --version
Bundler version 2.2.3

$ bundle --version
Bundler version 2.2.3

$ which bundler bundle

$ file "$(which bundle)" ; file "$(which bundler)"
/home/devel/.rvm/rubies/ruby-3.0.0/bin/bundle: Ruby script, ASCII text executable
/home/devel/.rvm/rubies/ruby-3.0.0/bin/bundler: Ruby script, ASCII text executable

$ du -h "$(which bundle)" ; du -h "$(which bundler)"
4.0K	/home/devel/.rvm/rubies/ruby-3.0.0/bin/bundle
4.0K	/home/devel/.rvm/rubies/ruby-3.0.0/bin/bundler

So, yeah, we are damn sure both bundler and bundle are the same program. And yet this error showed up when using bundler install:

$ bundler install
Could not find gem 'pry-doc x86_64-linux' in any of the gem
sources listed in your Gemfile.

Tried again with bundle (instead of bundler) and it worked 😲. It is worth nothing that as of this writing, the docs only mention bundle install and not bundler install.

It is also worth nothing that later I could not reproduce this problem and bundler install worked too.
