Removing Nodejs and Npm
sudo apt-get remove nodejs npm node
sudo apt-get purge nodejs
Now remove .node and .npm folders from your system
sudo rm -rf /usr/local/bin/npm
sudo rm -rf /usr/local/share/man/man1/node*
sudo rm -rf /usr/local/lib/dtrace/node.d
sudo rm -rf ~/.npm
sudo rm -rf ~/.node-gyp
sudo rm -rf /opt/local/bin/node
sudo rm -rf opt/local/include/node
sudo rm -rf /opt/local/lib/node_modules
sudo rm -rf /usr/local/lib/node*
sudo rm -rf /usr/local/include/node*
sudo rm -rf /usr/local/bin/node*
Go to home directory and remove any node or node_modules directory, if exists.
You can verify your uninstallation by these command, they should not output anything.

which nodejs
which npm
Installing NVM (Node Version Manager) script
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash
The command above will clone the NVM repository from Github to the ~/.nvm directory:
=> Close and reopen your terminal to start using nvm or run the following to use it now:
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
As the output above says, you should either close and reopen the terminal or run the commands to add the path to nvm script to the current shell session. You can do whatever is easier for you.
Once the script is in your PATH, verify that nvm was properly installed by typing:
nvm --version
# Output
0.34.0
Installing Node.js and npm
nvm install node
nvm install --lts
Once the installation is completed, verify it by printing the Node.js version:
node --version
#Output
v12.8.1
Npm should also be installed with node, verify it using
npm -v
# Output
6.13.4
Extra - [Optional] You can also use two different versions of node using nvm easily
nvm install 8.10.0 # just put the node version number Now switch between node versions
nvm ls
#output
-> v12.14.1
v13.7.0
default -> lts/* (-> v12.14.1)
node -> stable (-> v13.7.0) (default)
stable -> 13.7 (-> v13.7.0) (default)
iojs -> N/A (default)
unstable -> N/A (default)
lts/* -> lts/erbium (-> v12.14.1)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.17.0 (-> N/A)
lts/dubnium -> v10.18.1 (-> N/A)
In my case v12.14.1 and v13.7.0 both are installed, to switch I have to just use
nvm use 12.14.1
Configuring npm for global installations In your home directory, create a directory for global installations:
mkdir ~/.npm-global
Configure npm to use the new directory path:
npm config set prefix '~/.npm-global'
In your preferred text editor, open or create a ~/.profile fileif does not exists and add this line:
export PATH=~/.npm-global/bin:$PATH
On the command line, update your system variables:
source ~/.profile
That's all
