Install node on ubuntu 17.04 - node.js

Question

I installed node 8.0.0 on Ubuntu then followed this answer to make it work but now when typing node -v it says v4.7.2. I'd like to have v.8. The one I'm trying to install. Is it a problem with the symlink or what's up ?

I suggest you remove the ubuntu package
sudo apt-get remove --purge nodejs-*
then execute below shell script to install nodejs ... you must update your ~/.bashrc with a copy N paste of the lines mentioned in below ... vi install_node.sh
#!/bin/bash
# ............... top of cut ........................ install_node.sh
export NODE_VER=v8.0.0 # see available versions at https://nodejs.org/dist/
# pick parent dir of nodejs install ... comment out or remove ONE of below
# export CODE_PARENT_DIR=/opt/code # root owned dir ... requires you to sudo prior to npm install going forward
export CODE_PARENT_DIR=${HOME} # RECOMMENDED execute as yourself including npm install
# ......... following env vars are OK no edits needed
curr_OS=$( uname )
if [[ "${curr_OS}" == "Darwin" ]]; then
OS_ARCH=darwin-x64
elif [[ "${curr_OS}" == "Linux" ]]; then
OS_ARCH=linux-x64
else
echo "ERROR - failed to recognize OS $curr_OS"
exit 5
fi
if [[ -z ${CODE_PARENT_DIR} ]]; then
echo "ERROR - failed to see env var CODE_PARENT_DIR"
exit 5
fi
export NODE_CODEDIR=${CODE_PARENT_DIR}/nodejs
export COMSUFFIX=tar.gz
export NODE_NAME=node-${NODE_VER}
export NODE_PARENT=${NODE_CODEDIR}/${NODE_NAME}-${OS_ARCH}
export PATH=${NODE_PARENT}/bin:${PATH}
export NODE_PATH=${NODE_PARENT}/lib/node_modules
# ............... end of cut ........................ install_node.sh
# copy and paste above from ... top of cut ... to here into your file ~/.bashrc
echo
echo "NODE_CODEDIR $NODE_CODEDIR<--"
echo
echo "mkdir -p ${NODE_CODEDIR}"
echo
mkdir -p ${NODE_CODEDIR}
echo
echo "cd ${NODE_CODEDIR}"
cd ${NODE_CODEDIR}
echo
# this is compiled code NOT source
[ -f ${NODE_NAME}-${OS_ARCH}.${COMSUFFIX} ] && rm ${NODE_NAME}-${OS_ARCH}.${COMSUFFIX} # if file exists remove
echo "wget -q --show-progress https://nodejs.org/download/release/${NODE_VER}/${NODE_NAME}-${OS_ARCH}.${COMSUFFIX}"
wget -q --show-progress https://nodejs.org/download/release/${NODE_VER}/${NODE_NAME}-${OS_ARCH}.${COMSUFFIX}
echo
echo "tar -C ${NODE_CODEDIR} -xf ${NODE_NAME}-${OS_ARCH}.${COMSUFFIX}"
tar -C ${NODE_CODEDIR} -xf ${NODE_NAME}-${OS_ARCH}.${COMSUFFIX}
echo
[ -f ${NODE_NAME}-${OS_ARCH}.${COMSUFFIX} ] && rm ${NODE_NAME}-${OS_ARCH}.${COMSUFFIX} # if file exists remove
# ........... done ........... #
which node
node --version
# .... bottom of file install_node.sh
