Node.js installation fail. /usr/bin/env: ‘node’: No such file or directory

[Botspot]

I'm not exactly sure what is going on here, but it's been happening for a while.

Installing Node.js with install script
=> Downloading nvm from git to '/home/pi/.config/nvm'
=> Cloning into '/home/pi/.config/nvm'...
* (HEAD detached at FETCH_HEAD)
  master
=> Compressing and cleaning up git repository

=> nvm source string already in /home/pi/.bashrc
=> bash_completion source string already in /home/pi/.bashrc
/usr/bin/env: ‘node’: No such file or directory
=> Close and reopen your terminal to start using nvm or run the following to use it now:

export NVM_DIR="$HOME/.config/nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion
/home/pi/pi-apps/apps/Node.js/install: line 15: nvm: command not found
failed to install node.js! trying again with different NVM_DIR...
/home/pi/pi-apps/apps/Node.js/install: line 15: nvm: command not found
Failed to install Node.js using nvm!

Failed to install Node.js with install script!

Turns out the install script was seriously messed up. I've changed it to this:

#!/bin/bash

DIRECTORY="$(dirname "$(dirname "$( cd "$(dirname "$0")" >/dev/null 2>&1 ; pwd -P )")")"

function error {
  echo -e "\\e[91m$1\\e[39m"
  exit 1
}

#Checking if using armv6
if [ ! -z "$(cat /proc/cpuinfo | grep ARMv6)" ];then
  error "armv6 cpu not supported"
fi

if ! command -v curl >/dev/null ; then
  echo -e "\033[0;31mcurl: command not found.\e[39m
You need to install curl first. If you are on a debian system, this command should install it:
\e[4msudo apt install curl\e[0m"
  exit 1
fi

#Install nvm manager:
export NVM_DIR="$HOME/.nvm"
mkdir -p "$NVM_DIR"
wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash || error "Failed to install nvm!"

source "$NVM_DIR/nvm.sh" || error "Failed to source $NVM_DIR/nvm.sh"
source "$NVM_DIR/bash_completion" || error "Failed to source $NVM_DIR/bash_completio"

#Install NodeJS, if nvm fails, try again with a different 'NVM_DIR"
if ! nvm install --lts ;then
  echo "failed to install node.js! trying again with different NVM_DIR..."
  NVM_DIR="$HOME/.config/nvm" nvm install --lts || error "Failed to install Node.js using nvm!"
fi

It worked now.

I just noticed that nvm is downloading node arm64!! My system is armhf but using the 64-bit kernel. Time to see what happened to my PR on the nvm repo...

Fixed more than 8 various bugs in the scripts with commit e9de2f1.

We should be good to go from now on.
