AngularJS + Compass project fails to run locally on Windows (grunt dev / SCSS )

I’m trying to run an old AngularJS project locally on Windows 11. The project uses:

SCSS with Compass

Pug templates

Grunt tasks (grunt dev / grunt build)

Node.js + Bower

According to the README, I should just install npm and bower then run grunt dev to start a local dev server, but I’m getting errors.

Local setup with WSL2 (Ubuntu 22.04)

Installed Node.js, npm, Bower, Ruby 2.7, Compass 1.0.3 inside WSL2.

Ran:

npm install bower install grunt build grunt dev

Errors with grunt:

grunt build:

Errno::EACCES .../sass/plugin/compiler.rb: Permission denied @ rb_sysopen - .../build/app.css Aborted due to warnings

grunt dev:

Running "compass:dev" (compass) task Running "connect:server" (connect) task Started connect web server on http://localhost:9123 Fatal error: Exited with code 3

sass --watch sass:dev:

error sass/app.scss (Line 2: File to import not found or unreadable: compass/css3) Load path: /mnt/c/Users/Yassine/Desktop/erp-altanlagentool/sass Using Docker

Tried:

docker-compose up --build

Errors:

failed to compute cache key: failed to calculate checksum of ref ...: "/hybridisierungs-tool/dist": not found failed to compute cache key: failed to calculate checksum of ref ...: "/kommunale-waermeplanung/dist": not found

The Dockerfile contains multiple COPY .//dist ./webapp/ commands, which fail because these dist folders don’t exist yet — they are generated by grunt build.

What I want:

Run grunt dev locally so I can see the app with correct CSS, SCSS, fonts, and Pug templates.

Avoid changing any project files.

Understand whether WSL2 or Docker is the correct approach.

Additional info:

Ruby 2.7.8 installed in WSL2

Compass 1.0.3 installed

Node.js and npm installed

Docker fails because dist folders don’t exist yet

How can I run this project locally on Windows 11 using Docker (or WSL2) without modifying project files, so that grunt dev works and the app loads with correct CSS and fonts?
