Ruby image nvm cannot install node 20

[yart]

Hello!

I'm using the following Dockerfile:

ARG RUBY_VERSION=3.3
ARG DISTRO_NAME=bullseye
FROM mcr.microsoft.com/devcontainers/ruby:1-$RUBY_VERSION-$DISTRO_NAME

ARG NODE_VERSION="20"
RUN su vscode -c "source /usr/local/share/nvm/nvm.sh && nvm install ${NODE_VERSION} 2>&1"
# . . .

And when I'm building the image, it crashes with

RUN su vscode -c "source /usr/local/share/nvm/nvm.sh && nvm install 20 2>&1":
0.987 Version '20' not found - try `nvm ls-remote` to browse available versions.
------
failed to solve: process "/bin/sh -c su vscode -c \"source /usr/local/share/nvm/nvm.sh && nvm install ${NODE_VERSION} 2>&1\"" did not complete successfully: exit code: 3

In the same time, when I'm installing the same node's version locally, not from the Docker, it's done successfully.

Could anybody help me, please?

The issue you're encountering is likely due to the nvm environment not being fully initialized when running the su vscode -c command. Here's an updated version of your Dockerfile:

ARG RUBY_VERSION=3.3
ARG DISTRO_NAME=bullseye
FROM mcr.microsoft.com/devcontainers/ruby:1-$RUBY_VERSION-$DISTRO_NAME

ARG NODE_VERSION="20"

# Ensure nvm is properly sourced and initialized
RUN su vscode -c "export NVM_DIR="/usr/local/share/nvm" && \
    . /usr/local/share/nvm/nvm.sh && \
    nvm install ${NODE_VERSION} && \
    nvm use ${NODE_VERSION} && \
    nvm alias default ${NODE_VERSION}"

@yart Can you check if this works?
