Cannot read property 'resolve' of undefined when using npm to install a package

We do not have much information to work with (as the console output given by Node isn't very useful in this case), but it looks like NPM/Node messed something up while installing.
You stated that you've already tried to re-install Node. You should definitely also re-install NPM (This is a great tutorial to remove both completely: https://stackoverflow.com/a/20711410/10588376).
If you just forgot to mention that you also re-installed NPM and you already did it, I would recommend downgrading Node. You are running v12.4.0 which is the latest (not so stable) version of Node. You could download Node v10.16.0 (https://nodejs.org/en/), which is the LTS (Long Term Support) version of Node (LTS is the recommended version by Node).
As it seems downgrading solved the problem here: https://stackoverflow.com/a/56512076/10588376 (this is for Linux tho, but it could be worth a try on windows too)
Solution 2
Downgrading to node v8.16, then to v10.17 and finally to v12.13 did help for me.
For some reason it helped to install those old versions.
Solution 3
This happened to me due to conflicting NodeJS Versions on my machine. One method to you can try is to completely uninstall NodeJS and NPM using the following instructions https://stackoverflow.com/a/20711410/10588376 . And Reinstall NodeJS after this.
----OR----
You can do what I did (works in cases where NVM is installed) -
- Run npm cache clean --force
- Go to the control panel --> Programs --> Programs and Features
- Scroll down, Uninstall Node.js and check if another file called "nvm for windows 1.1.7" (Version does not matter) if it is present then uninstall that too. Make sure to note down any global npm packages that you have pre-installed as this deletes all instances of global npm packages.
- Reboot your machine
- Reinstall node.js from https://nodejs.org/en/ by following the installation process It should work now

I cannot use npm to do anything on my Windows 10 machine. I always get: npm ERR! Cannot read property 'resolve' of undefined.
I am using VSCode.
npm install npm -ggives me the same message as does "npm i". I have uninstalled Node and reinstalled it twice and it doesn't help. I removed the node-modules directory in my only development directory. I have no other ideas.
This is what the now complete log looks like:

Scott VanKirk almost 5 yearsA bit more info: This happens with both node 10.16 and 12.4. According to the node documentation, the node installation installs both node and npm and uninstalling node uninstalls npm as well. "npm cache clean --force" doesn't change anything

Scott VanKirk almost 5 yearsOkay, I've followed: stackoverflow.com/a/20711410/10588376) as Marvin has suggested. I've scrubbed any mention of NPM off my machine, rebooted, reinstalled Node 10.16 and STILL I get the same error any time I try to run NPM.

Scott VanKirk almost 5 yearsDowngrading worked! After uninstalling everything once again, I installed V8.16. npm worked. Then I installed V10.16 and V12.4 and both times npm worked again! WTF? I've never even had V8.16 on this computer and everything was working until just recently. I've been wracking my brains trying to remember any changes I made to this machine, but I got nothing. Any thoughts on this?

Skystrider over 4 yearsI didn't need to downgrade. Uninstall of node and npm and then reinstall fresh worked for me. First link in MarginJWendt's answer for how to completely remove node/npm worked for me.
