NPM cannot run dev in Docker Node container due to root owned files

When I run npm run development I am getting the error:

Creating api_node_run ... done

> dev
> npm run development

npm WARN logfile Error: EACCES: permission denied, scandir '/root/.npm/_logs'
npm WARN logfile  error cleaning log files [Error: EACCES: permission denied, scandir '/root/.npm/_logs'] {

I have a Docker Node container defined in docker-compose.yml as:

node:
    image: connectedplaces/api/node
    build:
      context: ./docker/node
      dockerfile: Dockerfile
    volumes:
      - .:/var/www/html

The Dockerfile is:

# Set base image.
FROM node:16.20

# Install git for faster package downloads.
RUN apt-get install -y git

RUN chown -R node:node /root/.npm

# Set the working directory to the project root.
WORKDIR /var/www/html

The container will launch successfully, and if I check the permissions with:

docker-compose run --rm --entrypoint ""  node ls -lart /root/.npm

The output is:

drwxr-xr-x 1 node node 4096 Sep  7 22:33 _logs
drwx------ 1 root root 4096 Sep  7 22:33 ..
drwxr-xr-x 1 node node 4096 Sep  7 22:33 .

I followed the ideas from Node Docker can't run dev command but I still cannot get around this error.
I have deleted the local image and rebuilt it, I have bumped the Node version in the Dockerfile and rebuilt, but nothing seems to work.

Any ideas what to do next?

    After trying every solution suggested the only one that worked was to create a new cache directory and set npm_config_cache to it in the Dockerfile:

    # Set base image.
FROM node:16.20

# Install git for faster package downloads.
RUN apt-get install -y git

RUN mkdir -p /home/node/app/.npm 
&& chown -R node:node /home/node/app/.npm

ENV npm_config_cache /home/node/app/.npm

# Set the working directory to the project root.
WORKDIR /var/www/html

    This was suggested in Error "Your cache folder contains root-owned files, due to a bug in previous versions of npm" while "npx create-react-app example_app" by @ASHBRN-PHNX Thanks

    Instead of "chowning" everything so it fits, it should make things better by using the "node" users uid and gid as build arguments. Consider:

    FROM node:16.20
ARG UID=1001
ARG GID=1001

RUN groupmod -g ${GID} node && usermod -u ${UID} -g ${GID} node

USER node

WORKDIR /var/www/html

    and

    services:
  node:
    build:
      context: .
      dockerfile: Dockerfile
      args:
        - UID=501
        - GID=501
    volumes:
      - .:/var/www/html

    for example.

    This way you could use the host users uid and gid for development (On macos it is often 501, on Ubuntu 1000/1001 I think). In prod – ypu can just use the default.
