couldn't install npm on ubuntu

Tried to install nodejs and npm on ubuntu 12.04. I googled and did it. Now, I could not install npm on machine.

sudo apt-get install npm

Which gives me this

This looks like you probably installed the chris-lea node.js ppa which is fine. However, you don't install npm from that ppa as it breaks the way debian packages work. Instead, just install nodejs. Once that's installed, run npm -v you should see it's now installed. If you didn't use the chris-lea ppa update your question on what webpage you Googled to find out how to install nodejs on Ubuntu.

Try installing NodeJs like this:

sudo apt-get install nodejs

Since NodeJs installs node and npm

Apt doesn't handle dependancy conflicts well, use snap or aptitude;

sudo aptitude install npm

I had to press "no" to the first solution it proposed, which did not include installing npm (that must be a bug in aptitude) then the second solution I pressed yes to hTHen check npm was installed:

npm --version

Problem is registry, execute this command,

npm config set registry 

I work on this way, check it work for you

I solved this issue by following this documentation.

Pointers to remember to work with npm:

mkdir ~/nodejs/ && cd ~/nodejs
sudo apt-get install npm
npm install
npm update

While developing applications, if nodejs needs any particular module then run

cd ~/nodejs
npm install modulename #for example sendgrid

Sometimes, modules needs to install globally; then use

sudo npm install modulename -g"

To remove a module:

cd ~/nodejs
npm uninstall modulename # if locally installed or
sudo npm uninstall modulename -g # if globally installed

npm prune helps to remove unmet dependencies

First, you need to install the PPA in order to get access to its contents:

curl -sL | sudo bash -

(This for version 9, which is the latest version at the time of writing).

And then

sudo apt-get install nodejs

Version conflict of manual installed npm and which comes with latest nodejs.

So you could try to remove nodejs, remove old npm and installed new nodejs again which comes with npm.

it worked in my case.

first-:

curl -o- | bash

then logout and come again and

 nvm install node

it will install npm . hope it will help

Installing nodejs will install npm, so just remove nodejs then reinstall it:

sudo apt-get remove nodejs
