Nvm: NPM install doesn't update the version of installed package

[harleyguru]

Hey,
I am updating existing global module, but it doesn't update even if the module is updated in node_modules.

For example,

$ npm i -g serverless # it's successfully installed, and I've confirmed in node_modules
$ serverless --version # this will print old version yet even if I restart the terminal

What's the problem?

What does which npm and which serverless print out?

Also, please always fill out the entire issue template - it's there for a reason.

@ljharb Thanks for your response.
Even if I install new version, it doesn't update version. which npm -> 5.10, which serverless -> 1.29.1
I've found out the reason. npm install didn't install latest version.

It's successfully installed, but just not updated version.
When I've been using just npm without nvm, I could update packages simply by running the following commands.
$npm i -g <package>
But after I started to use npm installed by nvm, it doesn't work any more.
I had to update the packages as below:
$npm update -g <package>
Thanks

That's definitely not a solution; what's probably happening is that your global npm/node is shadowing the nvm one, which would be clear if you'd filled out the issue template.

Try uninstalling your system node/npm, and then everything should work (without ever needing npm update).

Thanks for your answer @ljharb
But I have no node or npm in my system.
I've just installed them from nvm.

I’m happy to reopen this if you can fill out the issue template.

[harleyguru]

Oh, Thanks.
But It was too cumbersome to fill out..
maybe when I have some time later days, I will create new issue then.

[ljharb]

Please update this one at that time, rather than filing a new one. Thanks!

Got it @ljharb Thanks for your amazing support and responsibility!
I love NVM!

Hi @ljharb
It's my bad. the package I've tried to update was one installed originally by system npm.
This is not an issue with NVM.
Thanks again!
