How do you install `npm` on Ubuntu? - node.js

According to this page:
https://docs.npmjs.com/downloading-and-installing-node-js-and-npm
it says:
To publish and install packages to and from the public npm registry or
your company's npm Enterprise registry, you must install Node.js and
the npm command line interface using either a Node version manager or
a Node installer.
Then gives npm install -g npm which won't work cos npm isn't installed.
nvm doesn't work:
nvm install npm
Version 'npm' not found - try `nvm ls-remote` to browse available versions.
Clicking on the nvm link takes you to the nvm GitHub page.
Half way down I found this:
nvm install-latest-npm
which fails with:
nvm install-latest-npm
Attempting to upgrade to the latest working version of npm...
Unable to obtain npm version.
Any suggestions?

nvm is for installing node not npm, npm will be installed
What you're doing with nvm install npm, is attempting to install a node version called npm.
Do nvm install 14, let it run, check for errors, then once installed your have npm.

Just run these scripts and you are good to go.
sudo apt update
sudo apt install nodejs
It installs nodejs as well as npm.

how do I update Node.js using cmd?

Update Node.js version using command prompt
My installed version is
v14.15.1
LTS version is
v14.17.1
Using below two commands
install npm
npm install -g npm stable
install node using
npm install -g node
using command also but the version is not updated
its Works
1. sudo npm cache clean -f
2. sudo npm install -g n
3. sudo n stable
stabilize version installed
You install nvm first (Node Version Manager):
https://github.com/nvm-sh/nvm
Then you say nvm install <version>.
And when you want to upgrade... it's as easy as nvm install <version>
And you can switch between Node versions:
nvm use <version>`
And by adding a .nvmrc file into the root of your project, you can wire up your shell to automatically switch to the version of Node.js specified in the .nvmrc file.

How I can update nodejs and npm version?

I install nodejs and npm.
but now I want to update to the latest version, i tried many ways but it didn’t work.
For Node.js Upgrade:
Linux/Mac:
The module n makes version-management easy:
sudo npm install n -g
For the latest stable version:
sudo n stable
For the latest version:
sudo n latest
Windows:
Just reinstall node from the .msi in Windows from the node website.
For NPM Upgrade:
Kindly go through npm documentation for windows update.
For Linux/Mac:
You can upgrade to the latest version of npm using:
npm install -g npm#latest
Or upgrade to the most recent release:
npm install -g npm#next
managing node versions is easy with nvmfor linux or nvm for windows.
the docs for how to install them are available at their respective github repos.
Try to install the nvm first.
Nvm is a script-based node version manager. You can install it easily with a curl and bash one-liner as described in the https://github.com/nvm-sh/nvm. It's also available on Homebrew.
Assuming you have successfully installed nvm. The following will install the latest version of the node.
$ nvm install node --reinstall-packages-from=node

How to properly upgrade npm on debian when installed with apt

I have issue with jessie and npm.
I have installed package nodejs with sudo apt-get install nodejs, so it installed npm automatically.
I then want to install latest of npm using npm i -g npm#latest, which work fine except the apt npm version is conflicting.
I want to remove the conflicting apt installed version, or to know the official way to update npm, if installed from apt.
I am only able to update node using npm i -g n then n stable but it is impossible for me to upgrade npm
npm is distributed with Node.js- which means that when you download Node.js, you automatically get npm installed on your computer.
A quote from The npm Blog
The best way to install npm is to install node using the node.js installer. npm is installed as part of node.
It’s over at nodejs.org. It will give you a recent, working version of npm with all the paths in the expected places. This is the version that npm Inc and the Node.js project both support.
Once you’ve installed Node.js, you can make sure you’ve got the very most recent version of npm using npm itself by running this:
npm install npm -g
If you have issues, do not use sudo, read in documentation fixing npm permissions carefully and configure npm properly.

npm WARN npm npm does not support Node.js v9.1.0

I updated to the latest node v9.1.0 and now npm doesn't work.
npm WARN npm npm does not support Node.js v9.1.0
It turns out that the current installed npm is not compatible with the new node and has a hard time updating.
The solution is to uninstall npm and then reinstall node which will contain the correct version of npm.
Here's how:
Uninstall npm.
Mac:
sudo npm uninstall -g npm
Windows:
npm uninstall -g npm
Install node from https://nodejs.org
Uninstall the global instance of npm:
npm uninstall -g npm
This will cause your system to fall back on the version of npm installed by node 9.1.0 and the warning will disappear.
What worked for me was to delete npm and npm cache from C:\Users\chrisd\AppData\Roaming
Then I ran npm i -g npm#next for the latest version of npm for Node 9.x
NPMJS.org has issued a new release 11.27.2017 -- npm v5.6.0
(You may not have to delete the npm/npm cacheif you just upgrade, but I had already done that before finding the new release)
NPMJS Release notes
Fixed my issue update to 5.71
npm uninstall -g npm
npm i -g npm#next
Had similar issue in linux/ubuntu, below helped solving it.
Remove existing versions of npm and node:
sudo apt --auto-remove purge npm
sudo apt --auto-remove purge nodejs
Re-install node
for me worked
npm uninstall -g npm
npm i -g npm#next
No need for manual installation or clearing the cache.
Run with admin credentials if needed.
I saw this warning after I upgraded to Node 10.4.1 after that I just ran npm uninstall -g npm with -g flag to remove it globally and the error was gone. I guess it updated my npm to version 6.1.0
Solution :
Go to the path where you can find the debug log (this file is found in your npm-cache folder) C:\Users\yourname\AppData\Roaming
Delete the NPM and NPM-Cache folder, but DO NOT reinstall node. Once deleted go back to your command line and re-use the command " npm install -g npm#latest "
What worked for me - On Ubuntu
Install nodejs
sudo apt install nodejs
Install npm
curl -L https://www.npmjs.com/install.sh | sudo sh
If you are unable to uninstall npm, instead you can skip that step and just
Reinstall npm https://nodejs.org/en/
This error occurs when the npm version not compatible with the node version. However npm uninstall -g npm also gives the same error for me.
So following steps work for me.
Option 1:
Step1: Follow this directory
C:\Users(your username)\AppData\Roaming
Step2: Delete the npm folder. And if there is a folder called `npm cache, delete it also.
Step3: Run npm clean cache —force ( — force is now required to clean cache)
If the above option is not worked for you please follow the below steps.
Option 2:
Follow this directory
C:\Users(your username)\AppData\Roaming
Delete the npm folder and if there is one mom cache folder.
Run npm clean cache --force ( -- force is now required to clean cache)
Make sure everything to do with Nodejs is deleted and uninstalled.
Reinstall Nodejs.
I had the same issue with npm when I have updated Node js on windows. I tried many things but only working solution was :
First uninstall npm with below command
npm uninstall -g npm
Now Install latest version
npm install npm#latest -g
If you are using Mac and brew, that's how I've got rid of this problem:
Even though I installed and reinstalled node with brew, with last version 11.8.0, apparently it kept using the last version
fdecollibus$ npm install --global gatsby-cli
npm WARN npm npm does not support Node.js v11.8.0
npm WARN npm You should probably upgrade to a newer version of node as we

+ gatsby-cli#2.4.8
npm -v gave me back version 5.6.0. I've therefore noticed that /usr/local/lib/node_modules had wrong permissions assigned to root:wheel.
A chown did not fix the problem: I've had to manually delete the content of the folder (cd /usr/local/lib/node_modules and -careful - type rm -rf * ) to get rid of the folder.
Then I've run brew uninstall node and again brew install node, and finally npm -v gave me back 6.5.0
Executing npm uninstall -g npm gave me same error
Uninstall Node.js installed in the system
Goto c:\Program File\nodejs (default location of the nodejs installation). Remove all contents of the folder manually.
Remove npm, npm-cache folder from Roaming folder under your username.
Install Node.js again.
running npm install #angular/cli -g worked for me.
I was getting the below warning when I executed, npm install to install package.json for my angular project.

According to #Ilyich, I uninstalled global npm, npm uninstall -g npm
And then I executed npm install to install my package, it installed successfully.
Navigate to the Appdata by typing %AppData% in the run or search.
Delete the npm and npm-cache folder and then install the nodejs again. It solved the issue for me.
If you are getting the same warnings while creating or importing an Angular project in an IDE such as Eclipse ,do the following:
File->New->Angular
In the window that appears change the versions of Nodejs and NPM to "use system installation"
...
If the process crashes at "installing packages for tooling via npm"
Close the terminal in IDE and manually go to the project directory and do "npm install".
Refresh the project in IDE
I had a similar issue trying to install other stuffs.
And looks like the npm version was not compatible with my node version.
In my case i had npm 5.4.2 and node v10.15.0
At the end of this process i had the version npm 6.7.0 and node v10.5.0
First Option:
I downgrade the version of node and other tools.
On terminal execute the next command with the version to be installed. (Example if we need change to node 8.14.1)
1.- Npm install -g node#8.14.1
Then we execute the command to uninstall the version to be removed.
2.- Npm uninstall -g node#8.15.0
After that we need execute the next command to set the new path
3.- Npm update -g node#8.14.1
Finally we only need execute the version to see if the changes were added successfully
4.- Node -v
In this case we will see the version as 8.14.1 and we finished the process.
If you want do it for Appium and Npm version you can open a new terminal and follow the same steps in order to change the version. For example:
Npm install -g appium#1.7.2
Npm uninstall -g appium#1.10.0
Npm update -g appium#1.7.2
Appium -v
In my case you must have the next versions:
Node 8.14.1
Npm 6.4.1
Other Way:
To solve it i just execute in the terminal the next line.
curl -L https://npmjs.org/install.sh | sh
After download a few files (took around of 10 minutes to see results in the terminal) i was able to continue working with the new latest and compatible version of both tools.
The next WARM was displayed in this case.

I am on a macOS and what ended up working for me was uninstalling npm, relinking Node, and reinstalling Node through Homebrew. (Prereqs: Have Homebrew installed and have a very confusing setup where npm and Node don't work together)
1. To uninstall homebrew:
If you are on a Mac, you probably don't see the AppData\Roamingfolder; you should instead go to npm root -g and delete the npm_modules folder. Now, when you type npm --version your computer should be confused.
2. Reinstalling node:
Try doing brew install node and if you already have node installed, your computer will ask you to reinstall it. If you do brew reinstall node and your versions of brew and npm look good, then you don't need to do the last step!
3. If you need to link the correct version of Node:
This step was something I think was my fault since I think I had installed Node through Homebrew as well as the actual online download. Follow the suggestions after brew link node which should take you to brew link --overwrite node. There will be around 7 directories that the command will not be able to overwrite, which you should all delete using sudo rm -rf directory_name. (Do use your common sense, don't delete something important.) After you are finally able to run the brew link --overwrite node command without any errors, you should then do brew reinstall node since you don't have npm anymore.
Tada! You hopefully now have version of npm and node that hopefully can work together.
Just install latest version of Node.js from https://nodejs.org
This will automatically update npm for you
Easiest way I found was to install the latest node with brew and the latest npm manually:
brew uninstall node
brew install node
npm install -g npm#latest
This removed the warning message. For some reason brew wasn't linking the new npm installed by node while it was updating node itself.
The easiest way(for windows) is to use the installer to remove node, then use it to reinstall node, at which time it will install the correct version of npm. running the above uninstall commands does not work, since the wrong version of node is installed, otherwise you wouldn't have this issue.
You can uninstall node current version, and install a early version that support npm. Then run npm install npm#latest -g and install current node version.
It's work for me
lowering the npm version worked for me (windows 10):
npm i npm#6.14.11
To upgrade the npm and Node:
Step 1. Uninstall the npm:
Mac: `sudo npm uninstall -g npm`
Windows: `npm uninstall -g npm`
Step 2: Install the latest version of Node: https://nodejs.org/en/

Start with fresh copy of node, npm and cordova

I had a makeshift setup on Lubuntu that 'functioned' with sudo npm install. I used Ionic Framework generator to create projects and they functioned as well as the builds and deployment.
I upgraded to 15.04 and ever since had problems finding a solution that worked does not give EACCESS errors or grunt serve telling me
Upgrade warning - for the CLI to run correctly,
it is highly suggested to upgrade the following:
Please update your Node runtime to version >=0.12.x
Please update your Cordova CLI to version >=4.2.0 npm install -g cordova
then for npm install -g cordova to tell me
npm WARN engine cordova-serve#0.1.3: wanted: {"node":">= 0.12.0","npm":">= 2.5.1"} (current: {"node":"0.10.26","npm":"2.12.1"})
I have tried the "chown -R whoami /dir/of/npm"
I have delete npm, node install brew and created new installs for all.
I still get EACCESS errors, my yo ionic "grunt serve" deploys the browser but gives ERR_CONNECTION_REFUSED
I installed brew, manually deleted the npm folder and did a clean install. No joy
which node - /home/username/.nvm/v0.10.26/bin/node
node -v v0.10.26
which npm - /home/userna/.linuxbrew/bin/npm
npm -v 2.12.1
which cordova - /usr/local/bin/cordova
cordova -v 3.5.0-0.2.6
And for good meassure i thought if i installed node4 all my troubles would disappear.
I know i messed this up but i would like a clean start with node, npm(without sudo) and cordova. Any help would be appreciated
Ps: I have done most of the normal suggestions hence my question.
Did you installed node using nvm?
So try
nvm use 4.0.0
In general:
nvm install [VERSION]
nvm use [VERSION]
To use permanent:
nvm alias default [VERSION]
try also to install cordova again after updating node
npm install -g cordova
If all fails:
Uninstall node and reinstall propper using brew:
cd ~
sudo rm -rf .npm
brew update
brew uninstall npm
brew install npm
