[node.js] E: Unable to locate package npm

When I try to install npm with sudo apt-get install npm, I got following error:

E: Unable to locate package npm

Why can't apt find npm? I'm using Debian 9 and already did run

sudo apt-get install nodejs

This question is related to node.js npm debian apt-get apt

The answer is


For Debian Stretch (Debian version 9), nodejs does not include npm, and to install it as a separate package, you have to enable stretch-backports.

echo 'deb http://deb.debian.org/debian stretch-backports main' |
sudo tee /etc/apt/sources.list.d/stretch-backports.list
apt-get update -y
apt-get -t stretch-backports install -y npm

In Buster (Debian 10), npm is a regular package, so going forward, this should just work. But some of us will still be stuck partially on Stretch boxes for some time to come.


Download the the repository key with:

curl -s https://deb.nodesource.com/gpgkey/nodesource.gpg.key | apt-key add -

Then setup the repository:

sudo sh -c "echo deb https://deb.nodesource.com/node_8.x cosmic main \
                 > /etc/apt/sources.list.d/nodesource.list"
sudo apt-get update
sudo apt-get install nodejs

I ran into the same issue on Debian 9.2, this is what I did to overcome it.

Installation

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

Check installed versions

node --version
npm --version

I had a similar issue and this is what worked for me.

Add the NodeSource package signing key:

curl -sSL https://deb.nodesource.com/gpgkey/nodesource.gpg.key | sudo apt-key add -
# wget can also be used:
# wget --quiet -O - https://deb.nodesource.com/gpgkey/nodesource.gpg.key | sudo apt-key add -

Add the desired NodeSource repository:

# Replace with the branch of Node.js or io.js you want to install: node_6.x, node_12.x, etc...
VERSION=node_12.x
# The below command will set this correctly, but if lsb_release isn't available, you can set it manually:
# - For Debian distributions: jessie, sid, etc...
# - For Ubuntu distributions: xenial, bionic, etc...
# - For Debian or Ubuntu derived distributions your best option is to use the codename corresponding to the upstream release your distribution is based off. This is an advanced scenario and unsupported if your distribution is not listed as supported per earlier in this README.
DISTRO="$(lsb_release -s -c)"
echo "deb https://deb.nodesource.com/$VERSION $DISTRO main" | sudo tee /etc/apt/sources.list.d/nodesource.list
echo "deb-src https://deb.nodesource.com/$VERSION $DISTRO main" | sudo tee -a /etc/apt/sources.list.d/nodesource.list

Update package lists and install Node.js:

sudo apt-get update
sudo apt-get install nodejs

Your system can't find npm package because you haven't add nodejs repository to your system..

Try follow this installation step:
Add nodejs PPA repository to our system and python software properties too

sudo apt-get install curl python-software-properties 
// sudo apt-get install curl software-properties-common

curl -sL https://deb.nodesource.com/setup_10.x | sudo bash -
sudo apt-get update

Then install npm

sudo apt-get install nodejs

Check if npm and node was installed and you're ready to use node.js

node -v
npm -v

If someone was failed to install nodejs.. Try remove the npm first, maybe the old installation was broken..

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

Check if npm or node folder still exist, delete it if you found them

which node
which npm

Encountered this in Ubuntu for Windows, try running first

sudo apt-get update
sudo apt-get upgrade

then

sudo apt-get install npm

This will resolve your error. Run these commands in your terminal. These commands will add the older versions. You can update them later or you can change version here too before running these commands one by one.

sudo apt-get install build-essential
wget http://nodejs.org/dist/v0.8.16/node-v0.8.16.tar.gz
tar -xzf node-v0.8.16.tar.gz
cd node-v0.8.16/
./configure
make
sudo make install

in my jenkins/jenkins docker sudo always generates error:

bash: sudo: command not found

I needed update repo list with:

curl -sL https://deb.nodesource.com/setup_10.x | apt-get update

then,

 apt-get install nodejs

All the command line results like this:

If you have installed nodejs, then you also have npm. Npm comes with node.
