What's Wrong?

I have this setup script set for my environment (tried different varitions)

Network access: Full

Setup Script

#!/bin/bash
apt update && apt install -y gh

# Download and install nvm:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.4/install.sh | bash

# in lieu of restarting the shell
\. "$HOME/.nvm/nvm.sh"

# Download and install Node.js:
nvm install 24

nvm alias default 24

nvm use 24

However when I later ask claude "Run node --version", it responds

Check Node.js version
Check Node.js version
Bash
node --version
v22.22.0

Node.js version 22.22.0 is installed.

What Should Happen?

The version should be 24
