[question] how to update npm for local project

[unickq]

Hey,

Switching from Volta, looking for a way to pin npm version for the project.

fnm install 14
node --version > .node-version

node -v
v14.21.3

npm -v
6.14.18

Can the latest npm pin to the project somehow?
Running npm install -g npm@8 from the project dir doesn't work.

Use corepack by enabling it after installing a new Node version:

$ corepack enable

And in your package.json specify the package manager and version you want:

{
  ...
  "packageManager": "[email protected]",
  ...
}

Corepack will automatically install and use the version you specify. Not sure if Corepack is available for Node 14 though.

@sambauers
It's working for me for pnpm, but not for npm.
Seems like the symlink for npm is incorrect. I'm not sure if this bug is from fnm or corepack side.

[mikicho]

Ok.
It seems like this is from corepack side: nodejs/corepack#138

I'm wondering if we need to add --corepack-enabled-all option
WDYT?

[sambauers]

Right, I wasn't aware until now that corepack doesn't support npm.

Maybe setting the npm version in "engines" inside package.json will help here, and then non-corepack logic will take care of it.

[mikicho]

@sambauers it supports npm|. Just not by default. You need to run corepack enable --all`

[sambauers]

It doesn't officially support it. I can't see a way to hook in to fnm to be able to run that command. It needs to be a feature request for the author I think.

@Schniz WDYT about this?
Another option is to add an install hook
