How to fix this Error -npm

Question

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:

---

How can I fix this?

Answer 1

On ubuntu 18.04 following steps saved me

To remove the distro-stable version, type the following:

sudo apt remove nodejs

This command will remove the package and retain the configuration files.

sudo apt purge nodejs

As a final step, you can remove any unused packages that were automatically installed with the removed package:

sudo apt autoremove

Refresh your local package index by typing:

sudo apt update

Enable the NodeSource repository by running the following command

(optinal) If you need to install another version, for example 14.x, just change setup_12.x with setup_14.x

curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -

Once the NodeSource repository is enabled, install Node.js and npm by typing:

sudo apt install nodejs

Verify that the Node.js and npm were successfully installed by printing their versions:

node --version (v12.18.4)
npm --version (6.14.6)

Answer 2

It seems to me that you're running a newer version of Node, but an outdated version of NPM.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:

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

---

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