/usr/bin/env: node: Permission denied in Docker container using Symfony 6 "Encore" tool

I’m running a docker container with PHP and node installed through nvm. A Symfony 6 app is mounted into it.

I’d like to user Symfony 6’s "Encore" tool to compile my assets.

I connect to my container like this:

sudo docker exec -ti 860cb4e01268 bash

And then I move to the directory when my symfony app is mounted.

Typing npm run build returns the following message /usr/bin/env: 'node': Permission denied

Node is installed and $PATH seems correct, when I type node, I can enter the node console as expected. Same thing if I type /usr/bin/env: node.

Still from inside the container, a whoami returns "root", so I don’t get how I could have a permission issue.

Finally, if I directly run node node_modules/@symfony/webpack-encore/bin/encore.js prod, it works and builds my asset as expected.

I don’t get why a simple npm run build won’t work?

    Instead of installing node through nvm, I installed it like suggested here https://askubuntu.com/questions/720784/how-to-install-latest-node-inside-a-docker-container. A npm run build now works as expected.

    I finally updated my docker-compose.yml file like this:

      nodejs:
    image: node:16.16.0
    working_dir: /website
    command: npm run watch
    volumes:
      - /home/path-to-my-website-files-on-host-machine:/website
    ports:
      - 8888:8888

    This way, each time I edit something in a js or css file, everything gets automatically rebuild and minified by Symfony Encore/Webpack
