[Bug] Error loading base64 on Ruby 3.4 due to its removal from default gems

[44smkn]

Describe the bug

hen running the project with Ruby 3.4, an error occurs because the base64 library has been removed from the default gems. This results in a failure when attempting to require 'base64'.

To Reproduce

1. Set up your environment using Ruby 3.4.
2. Install coverband normally.
3. Run your application or tests.
4. Observe the following error message:

bundler: failed to load command: unicorn (/vendor/bundle/ruby/3.4.0/bin/unicorn)
<internal:/usr/local/lib/ruby/3.4.0/rubygems/core_ext/kernel_require.rb>:37:in 'Kernel#require': cannot load such file -- base64 (LoadError)
	from <internal:/usr/local/lib/ruby/3.4.0/rubygems/core_ext/kernel_require.rb>:37:in 'Kernel#require'
	from /vendor/bundle/ruby/3.4.0/gems/coverband-6.1.4/lib/coverband/reporters/web.rb:3:in '<top (required)>'

	from /vendor/bundle/ruby/3.4.0/gems/coverband-6.1.4/lib/coverband.rb:147:in 'Coverband::Reporters::Web.call'
	from config.ru:45:in 'Router#coverband'
	from config.ru:30:in 'Router#call'
...(omitted)

I think this file is related...?

coverband/lib/coverband/reporters/web.rb

Line 3 in 34dc51b

require "base64"

Expected behavior

The application should load without errors in Ruby 3.4. It appears that adding base64 explicitly in the Gemfile (e.g., gem 'base64') could resolve this issue.

Screenshots

I think it is not needed
