Those direction are a little outdated: the script assumes python2 is the default Python on the system. With this little tweak, you can install node as prescribed in the gist above by symlinking python to python2.

The benefit is that it may save you the trouble of combing through the comments thread in the original gist.

This only concerns the first gist. It's tested on Manjaro (based on Arch Linux), but it'll likely address the same issue for any Linux system that uses Python3 as default. I've used it myself from late 2014 onwards without problems.

• Add the following file to your home directory, inspect it.
• Update its permissions to executable: chmod +x install-node.sh
• Then let it go: ./install-node.sh

install-node.sh

#!/bin/bash

cd $HOME

LOCAL_DIR=$HOME/local
NODE_DIR=$HOME/node-latest-install

echo 'export PATH=$HOME/local/bin:$PATH' >> $HOME/.bashrc
. $HOME/.bashrc

mkdir $LOCAL_DIR
mkdir $NODE_DIR

# download a version of Node
cd $NODE_DIR
read -p "Which version of NodeJS? " V
if [ -z "$V" ]; then
  V="latest"
else
  V="v$V"
fi

# point whatever your python version is, to python2

if ! [ "$(readlink $LOCAL_DIR/bin/python)" = $PYTHON2 ]; then
  cd $LOCAL_DIR/bin
  ln -s $PYTHON2 ./python
fi

# build & install
cd $NODE_DIR
./configure --prefix=$LOCAL_DIR
make install # this will probably take more than 30 seconds...

if [ "$(readlink $LOCAL_DIR/bin/python)" = $PYTHON2 ]; then
  cd $LOCAL_DIR/bin
