hyperstack:install gives NoMethodError

I'm attempting to create a new Rails app with Hyperstack, but I get an error during the `hyperstack:install` step.

EDIT: reproduction repo: https://github.com/CodingItWrong/hyperstack_rails

```bash
$ ruby --version
ruby 3.0.1p64 (2021-04-05 revision 0fb782ee38) [x86_64-darwin20]
$ rails --version
Rails 6.1.3.2
$ rails new hyperstack_rails -T
$ cd hyperstack_rails
```

Add `gem 'rails-hyperstack', "~> 1.0.alpha1.0"` to `Gemfile`

```bash
$ bundle install
```

The version installed is `1.0.alpha1.8`

```bash
$ bundle exec rails hyperstack:install
```

Error output:
