Downgrade Nodejs and Npm - node.js

Hello everyone how i can downgrade my version of nodejs and npm under ubuntu ?
Thanks,

You can downgrade npm by simple pasting a needed version:
For example:
npm install -g npm#3.10.10
Be sure that it's downgraded:
npm -v
To downgrade nodejs, you can also do so by simple pasting a needed version.
For example:
$ npm install -g n
$ n 6.10.3
Be sure that it's downgraded:
$ node -v
v6.10.3

Failed to install Vue.js Cli

node -v: v8.10.0
npm -v: 3.5.2
While running npm install -g #vue/cli or sudo npm install -g #vue/cli I get the error below and failed to download Vue CLI
You are using a rather old version of npm. The current version is 6.9.0, and the packages you are working with are asking for npm >= 5.5.1.
You need to update your node version, if possible always use latest node version
Nodejs version 14.4.
And if you have project that required different node version then use
NVM - node version manager
Just use sudo for global install
sudo npm install -g #vue/cli

Can't install latest angular cli on ubuntu

I'm trying to install angular via ubuntu.
When I type the version commande node -v
I get v12.14.1
Then I try to install npm package sudo npm install -g #angular/cli
I get a warning
npm WARN npm npm does not support Node.js v10.15.2
ng version
I get angular-cli: 1.0.0-beta.28.3
The npm version is 6.13.4
The issue here seems to be that sudo node -v gives 10.15.2 where as node -v gives 12.14.1.
This means that there are 2 different node versions installed.
You can get around this by using sudo -E node -v or by deleting the link to the other node.js install by doing: rm /usr/local/bin/node.

I was trying to upgrade npm version, so updated node to v10.1.0 then did

Are you using Linux/Unix or Windows?
It works to me.
If Linux based you need to sudo npm install -g npm#latest (sudo)

Node and NPM versions don't match

The node and npm versions on my mac dont match. How do I downgrade npm to the same version as node?
Node:
$ node -v
$ v0.12.7
NPM:
$ npm -v
$ 2.14.4
npm is a package manager for node.js. They don't have to be the same version. npm also gets updated more frequently than node, so they could not be expected to keep their versions the same
If it helps, you can install any version of NPM. On debian distros, to use npm version 4.5.0 you need to do:
$ curl https://registry.npmjs.org/npm/-/npm-4.5.0.tgz
$ tar -xvzf npm-4.5.0.tgz
$ cd package/
$ [sudo] make install
Their versions are different because they are independent softwares. Their development is not synchronized.
I recommend updating NPM when you can; I'm running npm version 5.2.0
You can easily upgrade your NPM version using npm install -g npm
