Q:

How to fix this Error -npm

I tried to install npm and I got the following error.
I already removed npm and reinstall it again, but I again got the following error:

npm ERR! Linux 4.15.0-30-generic

How can I fix this?

A:

It seems to me that you're running a newer version of Node, but an outdated version of NPM.
You can do either of the following:

Try the latest stable version of NPM:
You can upgrade to the latest version of npm using: npm install -g npm@latest

Uninstall Node form your machine completely, go to their website and install the latest stable Node version. NPM comes with it.
