How NPM upgrades itself

In fact, using NPM to upgrade a variety of plugins is very convenient, such as I want to upgrade the express framework, using the following command

NPM Update Express

If your Express is a global installation, then

NPM Update-g Express

You can also use the install command to reload, which is equivalent to update:

NPM Install-g Express

However, if you want to upgrade NPM itself, you will encounter a bit of a problem, because Nodejs comes with NPM, so you cannot upgrade NPM globally, you need to locally upgrade NPM in the Nodejs installation directory:

D:CD "program Files\nodejs" NPM update npm
