Question

I can't find at all where npm has its global settings stored.

npm config get userconfig

C:UsersJack.npmrc

npm config get globalconfig

C:UsersJackAppDataRoaming
pmetc
pmrc

There's no files at either of these paths and yet

npm config get proxy -> returns my proxy url for work. which I want to delete.

npm config -g delete proxy

There is a problem with upgrading npm under Windows. The inital install done as part of the nodejs install using an msi package will create an npmrc file:

C:Program Files odejs ode_modules pm pmrc

when you update npm using:

npm install -g npm@latest

it will install the new version in:

C:UsersJackAppDataRoaming pm

assuming that your name is Jack, which is %APPDATA% pm.

The new install does not include an npmrc file and without it the global root directory will be based on where node was run from, hence it is C:Program Files odejs ode_modules

You can check this by running:

npm root -g

This will not work as npm does not have permission to write into the "Program Files" directory. You need to copy the npmrc file from the original install into the new install. By default the file only has the line below:

prefix=${APPDATA} pm
