Accessibility generator for capybara_accessible_selectors fails

[louis-antonopoulos]

In response to running rails new

rails new my-app-name \
 --skip_rubocop \
 --skip-test \
 -d=postgresql \
 -m=https://raw.githubusercontent.com/thoughtbot/suspenders/main/lib/install/web.rb

the accessibility generator #add_capybara_gems step raises an error:

Git error: command `git fetch --force --quiet --no-tags --depth 1 --

According to their instructions, it should be added to the Gemfile with a tag: like this:

Include in your Gemfile:

group :test do
  # It is recommended you use a tag as the main branch may contain breaking changes
  gem "capybara_accessible_selectors", git: "https://github.com/citizensadvice/capybara_accessible_selectors", tag: "v0.12.0"
end

In a new app, including this in the Gemfile breaks:

gem "capybara_accessible_selectors", git: "https://github.com/citizensadvice/capybara_accessible_selectors"

but this succeeds:

gem "capybara_accessible_selectors", git: "https://github.com/citizensadvice/capybara_accessible_selectors", tag: "v0.12.0"
