Problem when I execute npm install on docker

Question

Working on the same project as a colleague, when performing npm install I have the following problem, although none of my colleagues have the same problem. We all use docker

Answer 1

Since it fails on readFileSync/openSync, this can be related to file synchronization issues between Docker and your host (Windows). It fails in /var/www which is most likely the folder which you're sharing as a volume inside the Docker container.

As for the workaround, you can exclude a node_modules sub-folder and make it persistent.

If you're using docker-compose.yml, mount a persistent docker volume in place of your local node_modules directory, e.g.

...
  volumes:
    - .:/var/www
    - node_modules:/var/www/node_modules
