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.
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/
I just upgraded my project to use Node.js v9.0.0. When I start my project using npm, it tells me I should upgrade to a newer Node version, but I believe this is the newest version. I also believe I'm on the newest version of npm (5.5.1).
Do I need to worry about this warning? Is there a good way to resolve the issue?
Here's the full warning:
npm WARN npm npm does not support Node.js v9.0.0
npm WARN npm You should probably upgrade to a newer version of node as we
npm WARN npm can't make any promises that npm will work with this version.
npm WARN npm Supported releases of Node.js are the latest release of 4, 6, 7, 8.
npm WARN npm You can find the latest version at https://nodejs.org/
Now using node v9.0.0 (npm v5.5.1)
I've just upgraded to Node v9 and ran into the same issue. There's a Github issue for this here.
Following the advice to uninstall a global instance of npm has resolved the issue for me, using:
npm uninstall -g npm
With Node 10.6.0 on Windows 10 with Git Bash installed, I did this and all worked well:
1. Launch Git Bash terminal.
2. cd ~/AppData/Roaming
3. rm -rf npm
4. rm -rf npm-cache
5. npm install -g npm#latest
Check version and test on an existing project to verify (cd to project dir)...
6. npm -version
7. npm install
NB: Performing steps 2 through 4 via Windows Explorer could be faster.
9.0.0 is indeed the latest version available at the moment. The reason that NPM shows you this message is because NPM hasn't updated their unsupported.js yet to accept 9.0.0 as a supported version.
I would say that you can probably use it without problems, but if you stumble upon one, know that it's probably caused by a breaking change in Node.js 9.0.0 and will very likely be fixed by the NPM team soon.
npm does not support Node.js v9.1.0
Uninstall did not work for me
npm uninstall -g npm
Node.js v9.1.0 comes bundled with npm v5.5.1. The latest version of npm is also v5.5.1, however, the version bundled with Node.js isn't exactly the same as the original version from npm.
The following is what I needed to do on MacOS
To completely uninstall node + npm, do the following:
1. go to /usr/local/lib and delete any node and node_modules.
2. go to /usr/local/include and delete any node and node_modules directory.
3. download and install node from nodejs.org
Latest update Jan 2018: NPM has released version 5.6.0 to work with this.
How to upgrade npm:
Note if you are using node version 9 you will not be able to upgrade npm directly, since npm does not support version 9, so using nvm, downgrade node to latest stable release, that will make npm work, then use commandnpm install -g npm#latest to upgrade npm.
Install nvm:
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.8/install.sh | bash\n
export NVM_DIR="$HOME/.nvm"\n[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
Download and use node X version:
nvm install 4.4.2
nvm use 4.4.2
node -v
[sudo] npm install -g npm#5.3.x remove this problem for me. ubuntu 16.10
I downloaded and installed nodejs on Windows. I'm trying to uninstall the version of typescript I have to get to an older version. When I run
npm uninstall typescript
or
npm uninstall -g typescript
I get
npm warn uninstall not installed in C:\Program Files\nodejs\node_modules: "typescript#0.9.7"
How can I uninstall typescript without having npm uninstall work? Thanks in advance.
You should have been able to uninstall typescript with the command
npm rm typescript
npm rm -g typescript
which is equivalent to uninstall. If that doesn't work, it is safe to find the typescript directory in Windows Explorer under C:\Program Files\nodejs\node_modules and remove it.
This should get you to a state with no typescript installed:
npm ls typescript
npm ls -g typescript
both show (empty).
Second point: npm view typescript version is not showing you information about your local setup, but rather the state of the npm repository, so it will always show you the version that corresponds to typescript#latest. At the time you asked this question, it was 0.9.7; it is now 1.3.0
Finally: to install a specific version of typescript such as 0.9.5, do
npm install -g typescript#0.9.5
Also, in general, you should make sure you have the latest node and npm. Updating npm on windows is a little tricky; you should follow the guide here: https://github.com/npm/npm/wiki/Troubleshooting#upgrading-on-windows
I recommend you to reinstall npm as this shouldn't happen. When the issue is still going on, open the directory and manually remove the files from that package.
How can I switch which version of npm I'm using?
Currently:
$ npm -v
1.1.65
But I need: 1.0.x
I tried but got an error:
$npm version 1.0
npm ERR! version No package.json found
Anyone know how to use a different version of NPM? Thanks
Your NPM version is tied to your NodeJS version. As far as I can tell you can only have one NPM version per Node version. Using something like nodenv or, my favorite, asdf, you can define your node version per folder.
Per Node version (e.g. per folder) you globally install the version of NPM that you want to use.
$ npm install -g npm#x.x
Edit: You can also now specify NPM version in your package.json "engines" key, though it takes a little more work to enforce that declaration.
You can update npm without installing another version of node.js and npm is not tied to versions of node.js specifically.
Of course, as node.js advances and adds features so too does npm so there is some limit for npm depending on node.js but you SHOULD update npm as much as you can because there are important security patches and bug fixes.
This is a best practice for all software. Stability is not worth ignoring a security risk.
The command is npm install npm#latest -g to install it globally. This will install the latest version that will run with the node.js you have installed.
Additionally you can install a specific version of npm to your package.json in a project like this npm install npm#6.14 and you can use it locally. What is even more interesting is you can install a local version of node.js in a project and use it too!
Example:
I am running node 16.8.0 and I have npm 7.21.0 but I want to use an earlier version of npm but just for a project:
In the project directory
npm i --save-dev npm#6.14
This will put the earlier version of npm into the node_modules/.bin which will let you run it in relation to this project. If you type npm -v at this point you will get your global version.
If you type node_modules/.bin/npm -v you will get 6.14.15
Since you have made this version of npm the one for this project, when you use npm in your scripts it will use 6.14.15 and not the global version.
The same is true of node.js.
You can install an older version of node.js like this: node_modules/.bin/npm install --save-dev node#lts which will then add this version of node.js to the project.
You can test this by entering node_modules/.bin/node -v and in my example you will see the locally installed version number, in my example v14.17.3 although my global is v16.8.0
If you do this, your project scripts in package.json scripts will run the locally installed versions rather than the global versions.
You can test this out by creating a script in your package.json.scripts like this: "what:version": "npm -v && node -v",
Then if you run npm run what:version you will get
> what:version
> npm -v && node -v
6.14.15
v14.17.3
What value is this?
It is a way for you to package node and npm with your project. This can be especially valuable for large projects where you have many people working on the same project, so you have consistency across the board or if you have a build server that has a specific version of node + npm. Additionally if you have corporate requirements, etc.
Additionally there is npx which allows you to do so much more. Using npx you can even try something out without installing it.
Here is the documentation for npm: https://docs.npmjs.com/about-npm-versions
If you find you are needing to switch between different versions of node.js and npm you might want to use nvm https://docs.npmjs.com/downloading-and-installing-node-js-and-npm
When you install npm you only get the latest package, so you need to install specific versions individually, e.g:
npm install -g npm#5.6.0
Once you've done that, run a version check and you should see the version you've just installed:
npm -v
5.6.0
You can install specific version by bellow command.
npm install -g npm#6.14.11
For a specific version, use
npm install -g npm#x.y.z
And for the latest version, use
npm install -g npm#latest
