NPM command not found after installing Node via PKG (no brew)

Question

I tried to remove NPM and Node and reinstall them both. I'm a complete noob in the process as you'll notice.

I sadly can't remember the commands I used.

After I removed them, I ran node -v and it returned command not found and I ran npm -v and it returned command not found, so I thought the process was successful.

I then went to Nodejs website and downloaded the latest package for MacOS (v12.11.1) and ran the install. It said it was successful. I check node -v and it returned 12.11.1, as expected, but then I checked npm -v and it sadly returned npm not a command!!

If I run which node I get /usr/local/bin/node. If I run which npm I get nothing returned.

I've since tried lots of ways of removing them both again just in case something was missed but I get the same thing every time - no NPM!

Most of the answers on StackOverflow talk about Brew but I have not used Brew and I have tried so many of the other answers but just can't get NPM back.

The PKG installer mentions this: 'Make sure that /usr/local/bin is in your $PATH.' but not entirely sure what that means and if that's my problem or not.

Does anybody know a surefire way to remove all traces of both, so when I reinstall the PKG from Node, I get both Node and NPM installed and working correctly?

UPDATE:

I seem to have had some success since posting this question. I followed instructions at https://docs.npmjs.com/misc/removing-npm.html to manually remove 'everything NPM-rleated' and ran the installer again. Now when I check npm -v it returns to the latest version number 6.11.3.

I will test things a bit more before deleting/answering my own question.

To fix this problem I ran the following command as suggested by NPM:

To remove everything npm-related manually:

rm -rf /usr/local/{lib/node{,/.npm,_modules},bin,share/man}/npm*

All was OK after I reinstalled Node and checked NPM's version using npm -v.

Googling 'Adding to $PATH mac' returns this as the top result:

https://www.architectryan.com/2012/10/02/add-to-the-path-on-mac-os-x-mountain-lion/

Open up Terminal and run the following command:

sudo nano /etc/paths

Enter your password, when prompted.

Go to the bottom of the file, and enter the path you wish to add.

Hit control-x to quit.

Enter “Y” to save the modified buffer.

That’s it! To test it, in new terminal window, type:

echo $PATH
