npm install not creating node_modules inside dockerfile - node.js

Question

I am using a dockerfile to define a custom Wordpress distribution that uses React in frontend (via special theme).
To do that I am modifying the official Wordpress dockerfile and adding the theme, wget and npm as dependencies.
The problem is at the end of the dockerfile in the CUSTOM PART. npm install does not create the node_modules directory, but finishes successfully (just WARN messages). Then npm start fails gives the ERROR, because the rimraf and webpack npm packages are not installed.
Why is /var/www/html/wp-content/themes/lexi-master/node_modules not being created?
The error:
