Redis – nodemon/bin/nodemon.js: not found running from Windows 10 cmd

I am very new to all technologies used in the project that I am trying to run and work on in the future (docker, node.js, etc.).

I am trying to run node server by calling docker-compose up --build. I am running the server from my Win 10 cmd, running the server from linux is confirmed working.

I am getting

> [email protected] start /usr/src/server
backend | > nodemon index.js
backend |
backend | /usr/src/server/node_modules/.bin/nodemon: 1: /usr/src/server/node_modules/.bin/nodemon: ../nodemon/bin/nodemon.js: not found

backend | npm ERR! A complete log of this run can be found in:

What I tried and concluded (googling everywhere for over a week):

1. Preinstalling nodemon in package.json, installing globally
2. Finding out that there indeed is nodemon.js inside node_modules, I just cant seem to access it( with cd for example)
3. RUN npm install --save nodemon results in npm ERR! File exists: /usr/src/server/node_modules/.bin/nodemon
4. Many other solutions found on stackoverflow resulted in the not found or File exists error.
5. printenv prints: npm_package_dependencies_nodemon=^1.19.4 (not sure if it means something)
6. I tried installing nodemon globally after cleaning all docker images and running the command fresh

In my conclusion: nodemon is installed in modules, but I cant access it
