Error when trying to build storefront

Shopware 6 (German) Themes & Design

Hello,

We are trying to build storefront using these myprepaidcenter commands:

php bin/console bundle:dump
PROJECT_ROOT= ABSOLUTE_PATH_TO_PROJECT_ROOT / npm --prefix vendor/shopware/storefront/Resources/ run production
php bin/console theme:compile
php bin/console assets:install

But we get this error even if we install the module (npm install app-module-path --save);

Error: Cannot find module ‚app-module-path‘
at Function.Module._resolveFilename (internal/modules/cjs/loader.js:636:15)
at Function.Module._load (internal/modules/cjs/loader.js:562:25)
at Module.require (internal/modules/cjs/loader.js:690:17)

Does anyone have an ideea how we can solve this?

Thank you in advance.

Facing the same problem, please help me.
