npm command not working on ubuntu

Question

I installed node and npm on Ubuntu 14.04 and when I try to use any npm command, I get the following error:

/usr/local/lib/node_modules/npm/lib/config/cmd-list.js:113
module.exports.aliases = Object.assign({}, shorthands, affordances)
                            ^
TypeError: Object function Object() { [native code] } has no method 'assign'
at Object.<anonymous> (/usr/local/lib/node_modules/npm/lib/config/cmd-list.js:113:33)

at Object.<anonymous> (/usr/local/lib/node_modules/npm/lib/npm.js:471:3)

I'm new to using node and I didn't find any solution to such an error online

What was an exact command line you tried? Are you using sudo? — R. Richards

@R.Richards I agree we need the exact command, but i don't think it's related to sudo otherwise it would be EACESS error — Dhyey

You are right! We would be seeing that in the output. Good catch. — R. Richards

Im trying to install angular with npm using npm install angular command, even with sudo this isnt working. I already tried reinstalling node and npm once. — Pragati Basa

You are most likely running an old version of node.js (verify with node -v, at the time of writing this, the latest lts is 6.x). I suppose you tried to install it with apt-get install nodejs or similar. The packages shipped with ubuntu 14 are outdated, follow the advice on nodejs' download page instead, and do the following:

Step 1, remove the old packages:

sudo apt-get remove --purge nodejs

Step 2, type the following commands one after the other and follow the screen:

curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
sudo apt-get install -y nodejs

Now you have a version of nodejs installed that allows ES6 methods, as Object.assign is one of them

Is the deb link still valid for today?

This worked for me on Ubuntu 18.04:

sudo apt install nodejs
sudo apt install npm

npm might be older version,

so remove nodejs,

sudo apt-get remove nodejs
sudo apt-get remove npm

then,

sudo apt-get install curl #if you dont have curl

Node.js v6:

curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
sudo apt-get install -y nodejs
Node.js v7:

curl -sL https://deb.nodesource.com/setup_7.x | sudo -E bash -
sudo apt-get install -y nodejs
Node.js 8:

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs

for more info, package manager
