When I `init` then `build` a brand-new project, without making any changes, it fails to build css

[Grant Birchmeier]

Expected behavior and actual behavior

Expected behavior:

Init'ing a new project and building the freshly-init'd project should work without error:

> gem install middleman
  # (installs middleman-4.4.3.gem, middleman-cli-4.4.3.gem, middleman-core-4.4.3.gem)
> middleman init foo
  # (also installs middleman-autoprefixer-2.10.1)
> cd foo
> bundle exec middleman build

I expect that last command complete without errors.

Actual behavior:

The build command fails to build the css file:

2004 ~/tmp/mmtest/foo$ bundle exec middleman build

There were errors during this build, re-run with `middleman build --verbose` to see the full exception.

Full output with --verbose is here: verbose_output.log

Steps to reproduce the problem (from a clean middleman installation)

As detailed above.

Additional information

• Ruby version: 3.2
• Middleman version: 4.4.3
• OS version: OS X 12.5.1 "Monterey"

Further investigation

If I delete source/stylesheets/site.css.scss completely, then I get no error (and obviously no generated css file), so clearly the problem is with the css generation.

In fact, the error occurs for any and every css, sass, or scss file. It doesn't matter if the file is empty or has valid or invalid content-- it always fails the same for each file.

For instance, this tree structure:

2065 ~/tmp/mmtest/foo$ tree source/
source/
├── images
├── index.html.erb
├── javascripts
│   └── site.js
├── layouts
│   └── layout.erb
└── stylesheets
    ├── blah.css
    ├── doop.sass
    ├── poo.pants
    └── site.css.scss

results in:

2042 ~/tmp/mmtest/foo$ bundle exec middleman build

Oddly, the non-style file is copied correctly.

Ugh, why does the current gem release have issues that were identified and solved more than a year ago?
