Error: Cannot find module '/var/www/start' in Docker - Windows 10 / Windows Server

Current behaviour

When booting the vue-storefront-app service using docker on Windows 10 Professional Edition. The PM2 service will result in an error if you configure the NODE_ENV from “dev” to “production” (further explanation can be found below in the Additional Information section) which will result in the following error across all PM2 instances: “Error: Cannot find module ‘/var/www/start’”

After it phases through the docker configuration and setup via docker. These are the logs:

PM2 boots the 4 instances successfully, but then soon after encounters, an error: “Error: Cannot find module ‘/var/www/start’”. View logs for more information ──────────┬────┬─────────┬─────┬────────┬─────────┬────────┬──────┬───────────┬──────┬──────────┐

Expected behaviour

The service should boot and users should be able to connect to localhost:3000 or 0.0.0.0:3000 to see the vue-frontend.

Steps to reproduce the issue

• By default the Repository has been configured so that the vue-frontend runs in DEV mode, therefore if you need to replace the key word: “dev” to “production” in the docker file and the docker-compose files - can then execute “docker-compose up -d” to build the docker image.

• Currently: this hasn’t been configured to run on a windows platform (including my windows 2019 servers).

Can you handle fixing this bug by yourself?

• [ X ] NO

Which Release Cycle state this refers to? Info for developer.

Pick one option.

• [ X ] This is a bug report for current Stable version on https://demo.storefrontcloud.io and should be placed in next stable version hotfix - In this case Developer should create a branch from hotfix or master branch and create Pull Request 4. Hotfix back to hotfix.

Environment details

• Browser: Not applicable as server doesn’t even run
• OS: Windows 10 Professional Edition - Version 1909 (OS Build 1836.836)
• Node: v12.16.3
• Code Version: Latest: https://github.com/DivanteLtd/vue-storefront/tree/6cd57ab269a8a31ed8eb5a18ebc8934abe1b9b55

Additional information

• The current version of vue-frontend works perfectly fine if you don’t change the NODE_ENV settings from “dev” to “production” in the docker file and the docker-compose files. The repository itself defaults back to “yarn dev” due to the shell file (vue-frontend.sh) when you execute “yarn start” / “npm start”.

• By default when directly downloaded from the repository https://github.com/DivanteLtd/vue-storefront - “yarn start” is the equivalent of “yarn dev” .

• As vue-storefront caches the vue-storefront interface. When testing this issue please use a fresh incognito mode page. (Don’t be tricked by the cached version from the previous dev build).

Had the same issue, resolved by fixing ecosystem.json as mentioned in: https://github.com/DivanteLtd/vue-storefront/issues/4191#issuecomment-602535658

I have the same issue but in kubernetes pods . The cmd “yarn start” works fine in linux machine and macOs but not inside the pods , showing this error “Error: Cannot find module ‘/var/www/start’” . Any idea how to fix it please ?

Have you made sure to run “yarn build” before running “yarn start”. Yarn start requires the build files that are created in var/www/.

It is an honest mistake, but I’m pretty sure that is your issue
