How can I change the version of npm using nvm?

I've been using NVM to install the latest versions of nodeJS for my node work. It works totally fine for installing separate versions and switching between them. It also installs the latest version of NPM within each local .../bin folder along with the node binary. However, there doesn't seem to be any way to switch the version of NPM that I'm using (or at least I can't figure it out).

The only solution I can think of myself is to delete the binary that it's defaulting to (which is the NPM that was installed when I first installed node with NVM), and in its place to put the latest NPM binary. However, I'm wondering if there are any better ways to go about doing this.

Why do you wanna change the version of NPM, it's not like you gonna install any package that only works with an old version of NPM. And after node 0.6, node comes with the latest NPM. So changing node version will also change npm version.
except it doesn't through NVM. yes - node comes with NPM, but that just means that it installs a binary alongside it. i can see both binaries in their respective folders, but when i run "nvm use v0.6.13", the npm binary in use remains the one that was installed with the older version of node, instead of the one installed with the newest version.
Here's the code for npm: github.com/creationix/nvm/blob/master/nvm.sh#L135-148 , which is not needed since, 0.6, so maybe you should try to remove that part. That should help. You can also create an issue on github.
I am working on this problem right now, any help appreciated - stackoverflow.com/questions/50976138/…

EDIT: several years since this question was first answered, as noted in a newer answer, there is now a command for this:

nvm now has a command to update npm. It's nvm install-latest-npm or nvm install --latest-npm.

nvm install-latest-npm: Attempt to upgrade to the latest working npm on the current node version

nvm install --latest-npm: After installing, attempt to upgrade to the latest working npm on the given node version

Below are previous revisions of the correct answer to this question.

Over three years after this question was first asked, it seems like the answer is much simpler now. Just update the version that nvm installed, which lives in ~/.nvm/versions/node/[your-version]/lib/node_modules/npm.

I just installed node 4.2.2, which comes with npm 2.14.7, but I want to use npm 3. So I did:

cd ~/.nvm/versions/node/v4.2.2/lib
npm install npm

Easy!

And yes, this should work for any module, not just npm, that you want to be "global" for a specific version of node.

EDIT 1: In the newest version, npm -g is smart and installs modules into the path above instead of the system global path.

Thanks @philraj for pointing this out in a comment.


and for those who don't know where their nvm is, like me, run a which npm.
And if you want a version of npm other than the latest, run npm install npm@major.minor.patch to get that specific version, e.g. npm@3.10.9
Something similar works for nvm-windows too, e.g. cd ~/AppData/Roaming/nvm/v5.10.1.
For anyone using nvm for Windows, the same can be done as above (running npm install npm), but in the node install locations for Windows. In Windows 10, this is ~/AppData/Roaming/nvm/[your-version]. i.e Users\myusername\AppData\Roaming\nvm\v9.7.1
Even easier: nvm install-latest-npm as answered below by samlandfried -stackoverflow.com/a/47519162/5991278

npm install npm@x.x.x -g
npm install npm@5.4.0 -g

Though the question is about nvm, I actually came here for that, thanks. Upvoting.
This command will work regardless of which version of Node you've installed with nvm, because of the -g flag. When you switch versions in nvm, the npm version will change as well, so it's easy to undo this action.

nvm doesn't handle npm.

So if you want to install node 0.4.x (which many packages still depend on) and use NPM, you can still use npm 1.0.x.

Install node 0.6.x (which comes with npm 1.1.x) and install nvm with npm:

npm install nvm
. ~/nvm/nvm.sh

Install node 0.4.x with nvm:

nvm install v0.4.12
nvm use v0.4.12

Install npm using install.sh (note the -L param to follow any redirects):

curl -L https://npmjs.org/install.sh | sh

This will detect node 0.4.12 and install npm 1.0.106 in your ~/nvm/v0.4.12/lib/node_modules folder and create symlink for nvm

~/nvm/v0.4.12/bin/npm -> ../lib/node_modules/npm/bin/npm-cli.js

If you try to run npm, it will still give an error but if you do nvm use v0.4.12 again, it should now work.


Thanks! A note that the url has changed to: curl https://npmjs.org/install.sh | sh
Is this a really old answer now? My npm is downloaded by nvm automatically as a dependency of the node version I'm using.
Yeah. It's old. If you're still using node 0.4 and an old nvm you might see this issue.
The URL has been changed again to force www. Use curl -L to follow the redirect.

nvm now has a command to update npm. It's nvm install-latest-npm or npm install --latest-npm.


Do you have a link to the documentation for this?
From nvm help console output: --latest-npm After installing, attempt to upgrade to the latest working npm on the given node version I didn't find a reference to this in the nvm docs, though. Please share if you find it.
Thank you! This really should be marked as the correct answer.
its only available on 32 bits
when i ran this, it updated node as well

I'm on Windows and I couldn't get any of this stuff to work. I kept getting errors about files being in the way. This worked though:

cd %APPDATA%\nvm\v8.10.0           # or whatever version you're using
mv npm npm-old
mv npm.cmd npm-old.cmd
cd node_modules\
mv npm npm-old
cd npm-old\bin
node npm-cli.js i -g npm@latest

cd %APPDATA%\nvm\v8.10.0 # or whatever version you're using
rm npm-old
rm npm-old.cmd
cd node_modules\
rm -rf npm-old

And boom, I'm back in business.


Thanks, this worked for me as well, on Windows. (had same issue of file conflicts)
Worked for me thx. Am using nvm on Windows to manage node and wanted to uplift nvm after switching to node version. Had to run console with elevated permissions. My path nodejs folder is "C:\Program Files\nodejs" which is an alias for a.n.other location on my machine nvm uses to cache downloads (not APPDATA), guess I elected a different location when installing nvm.
Thank you, they probably need to fix the way npm update on every old nodejs version on nvm windows.
Worked on windows with nodejs v10.15.3, had to change mv to ren and rm to del and rmdir for me.
I found that when upgrading from npm@6, I also had to rename npx and npx.cmd. Not sure what version introduced npx.

In windows, run your terminal as admin (in case there are permission issues as I had). Then use a specific node version (say 7.8.0) by

nvm use 7.8.0

then update your npm to desired specific version by

npm install -g npm@5.0.3

Changing npm versions on linux based OSs isn't a straight forward one command process yet. I have done following to switch back to older version of npm. This should work to get any version of npm working. First install the version of npm you want to use:

sudo npm install -g npm@X.X.X

Remove the sym link in /usr/local/bin/

sudo rm /usr/local/bin/npm

Recreate the sym link using the desired version of npm you have installed

sudo ln -s /usr/bin/npm@X.X.X /usr/local/bin/npm

followed these instructions trying to go from 2.14.7 to 2.15.9, and now when I type npm -v, I get 3.8.6. Dammit.
After trying several things, for me, just using sudo npm install -g npm@x.x.x gets me that version responding from npm -v. This at least worked going from 4.x to 2.15.9, anyways.
In my case sudo npm install -g npm@4.6.1 only installed 4.6.1 but npm 5.1.0 was still used. Your tip help me switch to 4.6.1.

find the node and npm version you want to use from here https://nodejs.org/en/download/releases/ nvm use 8.11.4 you already got the npm 5.6 with node 8.11.4

Just go with nvm use node_version


That works fine for the first time. If you upgrade run npm i -g npm from an older node version and it updates to latest, your npm version will be the latest.

By looking at www.npmjs.com/install.sh I found there is a way to install a specific version by setting an environment-variable

export npm_install="2.14.14"

Then run the download-script as described at npmjs.com:

curl -L https://www.npmjs.com/install.sh | sh

If you omit setting the npm_install variable, then it will install the the version they have marked as latest


I had to use curl -L https://www.npmjs.com/install.sh | sudo sh, aaaaand this method did not work, getting me the latest version even though I had exported said environment variable. God dammit. I wanted version 2.15.9 from 2.14.7, answer below put me at 3.8.6, and now this answer puts me at 4.0.2. WTF.

We can easily solve this using n.

To install n

>> npm install -g n

To switch versions

>> n latest

To switch to particular version

>> n 10.16.0

What about npm i -g npm? Did you try to run this as well?


This is always the quickest and easiest I normally use.

Slight variation on the above instructions, worked for me. (MacOS Sierra 10.12.6)

npm install -g npm@3.10.10
rm /usr/local/bin/npm
ln -s ~/.npm-packages/bin/npm /usr/local/bin/npm
npm --version

I had same issue after installing nvm-windows on top of existing Node installation. Solution was just to follow the instructions:

You should also delete the existing npm install location (e.g. "C:\Users\AppData\Roaming\npm") so that the nvm install location will be correctly used instead.

You can install two versions of node using nvm, and install different version of npm on each node environment.
For example, nvm install 14.18.0 and nvm install 14.18.1 will install two separate node environments.

In 14.18.0, you can use npm v6 (installed by default).
In 14.18.1, you can use npm v7 (install with npm install -g npm@7).

This way you can switch different npm version without pain.

$ nvm use 14.18.0
Now using node v14.18.0 (npm v6.14.15)
$ nvm use 14.18.1
Now using node v14.18.1 (npm v7.24.2)

In my case I updated npm from version 6 to 8 in a node environment set to version 10 by nvm. This resulted in npm not working anymore, rendering the answers I found here useless.

I finally resorted to clearing the nvm folder:

rm -rf ~/.nvm/versions/node/*

Afterwards I could work with nvm and npm again. My lesson: Never install a fresh npm version with npm. nvm install-latest-npm seems to let you safely update within legacy environments.

The easy way to change version is first to check your available version using nvm ls then select version from the list nvm use version

For some reason npm install -g npm@X.X.X didn't work, so I've changed version of npm in package.json in npm folder

➜  ~ which npm
/opt/homebrew/bin/npm

and then run

npm install npm

NVM Installation & usage on Windows

Below are the steps for NVM Installation on Windows:

NVM stands for node version manager, which will help to switch the your node versions for specific use. It also allows the user to work with multiple npm and node versions.

Install nvm setup. Use command "nvm list" to check list ofinstalled node version. Type "nvm use version number[6.9.3]" to switch versions. For more info
