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. - Farid Nouri Neshat
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. - thisissami
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. - Farid Nouri Neshat
I am working on this problem right now, any help appreciated - stackoverflow.com/questions/50976138/… - Alexander Mills

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.

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.

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.

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 [email protected]

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/[email protected] /usr/local/bin/npm

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 [email protected]

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

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

Just go with nvm use node_version

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

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

npm install -g [email protected]
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.

For some reason npm install -g [email protected] 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
