Node and npm not getting recognized after getting installed from shell script in gitlab ci

Keywords´╝Ü linux shell docker gitlab-ci

Question: 

I am trying to install nodejs using a shell script file named install-nodejs.sh in gitlab ci job in pipeline. Installation is successful and node displays the version while within install-nodejs.sh file but when I say node -v in gitlab-ci.yml file it doesn't recognize node command, what am I doing wrong?

I am created a shell script to install nodejs and set export path but still node is not getting recognized

install-nodejs.sh file code

#!/usr/bin/env bash
set -e

command -v node > /dev/null | NOT_INSTALLED=1
if [[ "$NOT_INSTALLED" != "1" ]]
then  
  mkdir /usr/local/nvm
  NVM_DIR="/usr/local/nvm"
  NODE_VERSION="10.12.0"
  NVM_INSTALL_PATH="$NVM_DIR/versions/node/v$NODE_VERSION"
  rm /bin/sh && ln -s /bin/bash /bin/sh
  curl --silent -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash
  source ~/.nvm/nvm.sh
  nvm install $NODE_VERSION
  nvm alias default $NODE_VERSION
  nvm use default
  export NODE_PATH="$NVM_INSTALL_PATH/lib/node_modules"
  export PATH="$NVM_INSTALL_PATH/bin:$PATH"
fi

and gitlab.yml file code where i am calling this file

test_install_nodejs:
  <<: *default_job_template
  stage: build
  script:
    - ./scripts/install-nodejs.sh
    - node -v
    - npm -v
    - npm install -g newman

node -v in gitlab.yml file is not recognizing node but I can see the node installation is successful from shell file above.
