Uninstall node from /usr/local/bin/node

Question

I am having a problem uninstalling a package node that does not even exists but still shows up in the path, weird it is or am I dumb... It's contradicting with nodejs and I wana get rid of it and install a fresh node symlink to nodejs so that I have a single source of truth. So far I have tried most the popular package managers.

Answer 1

Got some help from this and run the following:

sudo rm -rf /usr/local/bin/npm
sudo rm -rf /usr/local/bin/node
sudo rm -rf /usr/local/lib/node_modules/
sudo rm -rf /usr/local/include/node/
sudo rm -rf /usr/local/share/man/man1/node.1

Then I installed nodejs using the official method as mentioned on the Node.js website -> instructions

TL;DR Run the following:
12.16.2 being the LTS version as of today.

curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
sudo apt-get install -y nodejs

The final result I got:

durrani@ideapad:~ $ node --version
v12.16.2
durrani@ideapad:~ $ nodejs --version
v12.16.2
durrani@ideapad:~ $ which node
/usr/bin/node
durrani@ideapad:~ $ which nodejs
/usr/bin/nodejs
