I have this error message "npm ERR! Linux 5.4.72-microsoft-standard-WSL2" on my terminal when I run "npm install"

I have this error message : npm ERR! Linux 5.4.72-microsoft-standard-WSL2 on my terminal when I run npm install. I'm on a vue.js app and I have this message since I installed vuetify.
Here is the whole error message :
npm ERR! Linux 5.4.72-microsoft-standard-WSL2

npm ERR! npm v3.10.10
npm ERR! cb.apply is not a function.
I also cannot install the latest version of npm I think this is related to the problem. (I have this version v3.10.10).
And when I run npm run serve I have this :

I have the Vue.JS version # vue / cli 4.5.12.
At last, I have a Window PC and I have installed linux and ubuntu.
I thank you in advance if you can help me.

Your npm version is outdated. Your version is 3.x but we're currently at 7.x
Run
npm update -g
and then try again.

What does it mean? How can I fix it? Thanks in advance.

Well it does seem like you haven't installed the http-server package.
Try the line below. It should work if it is included in your package.json
$ npm install
otherwise try:
$ npm install http-server
