  • 772

I was using ubuntu16.04 upgraded to ubuntu 18.04. followed some tutorial to remove npm, but now stuck. I have:

~$ npm list -g 
bash: /usr/bin/npm: No such file or directory

and:

     sudo apt-get install npm

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

    Follow up: Latest instructions to install nodejs on Ubuntu. Official Nodejs docs

    Original answer is below.

    I was having the same problem. After a lot of search online I managed to find a solution.

    The following is what solved it for me:

    Remove old nodejs installation and update packages.

    sudo apt-get remove nodejs npm
sudo apt-get update
sudo apt-get upgrade

    For 8.x node installations:

    curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -

    For 12.x node installations:

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

    Install:

    sudo apt-get install -y nodejs

    Test the installation:

    ~$ nodejs -v
v8.11.3 // <- node 8.x
v12.13.1  // <- node 12.x

~$ npm -v
5.6.0 // <- node 8.x 
6.12.1 // <- node 12.x
