Installing in a Ubuntu docker image

[vulkanosaure]

Hi,

I'm trying to install uWebSockets.js on a vanilla Ubuntu docker image, in which I installed node
When running the container, I get the error

_Error: Cannot find module 'uWebSockets.js'

Require stack:

- /var/www/socket/main.js

    at Module._resolveFilename (node:internal/modules/cjs/loader:1077:15)

  requireStack: [ '/var/www/socket/main.js' ]

}_

Here's my dockerfile

FROM ubuntu

WORKDIR /var/www/socket

#install node
RUN apt-get update
RUN apt-get install -y ca-certificates curl gnupg
RUN mkdir -p /etc/apt/keyrings
RUN curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg
RUN echo "deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https://deb.nodesource.com/node_18.x nodistro main" | tee /etc/apt/sources.list.d/nodesource.list
RUN apt-get update
RUN apt-get install nodejs -y

#install curl + bun
RUN apt upgrade
RUN apt install curl
RUN apt install unzip
RUN curl -fsSL https://bun.sh/install | bash

#install uWebSockets
RUN ~/.bun/bin/bun install uNetworking/uWebSockets.js#v20.33.0

CMD ["node","main.js"]

During the creation process, i can see the message
installed uWebSockets.js@github:uNetworking/uWebSockets.js#c10b47c
Which seems to say that uWebSockets has been correctly installed

I'd went to the node_modules folder to confirm if the uWebSockets.js folder is there,
The command which node returns /usr/bin/node
and cd /usr/bin/node returns can't cd to /usr/bin/node
as if it's a problem of access right

The content of main.js is the same as the example in the readme.

Any idea of how to troubleshoot this ?
Thanks in advance.
