    I could not get the solution to work, which was given here.

    A different solution propossed from the same source which itself linked to here worked for me:

    I first removed node and npm completly (To be precise all packages with the name in it, but I am not sure this is necessary). Then I used the give install command:

    curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash - &&
sudo apt-get install -y nodejs

    This is for Ubuntu and node version 18, but you can find other operating systems and versions as well (look here).

    I hope this helps someone.

    Seems like an issue with WSL Ubuntu 22 Jammy and 8.5.1 package.
    You may have luck installing a different package version, but I had issues with this.
    Installed WSL Ubuntu 20 with 6.14.4, issue was gone.

    This was an issue for me on Windows 10, using WSL2 and Ubuntu 22.04 LTS. The other solutions in this post did not help, and I was unwilling to downgrade to Ubuntu 20. Instead, I managed to fix it by removing all node-related packages with apt and then installing node via nvm as per this guide by Microsoft.

    So to remove the packages:

    sudo apt-get remove --purge nodejs npm

    Then install nvm…

    curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/master/install.sh | bash

    Restart the terminal. Then, make sure nvm is installed:

    nvm --version

    Finally, use nvm to install the latest version of node and npm:

    nvm install node

    Check to make sure node and npm are installed:

    node --version
npm --version

    Hope this helps!
