.npmrc failed to replace env in config

Question

Me and my colleagues have a problem with .npmrc

Most of us are on Mac OSx and this works

@REGISTRY_NANME:registry=https://gitlab.com/api/v4/packages/npm/ //gitlab.com/api/v4/packages/npm/:_authToken=${NPM_TOKEN}

But for me it don't work, but without {} like below, it works for me @REGISTRY_NANME:registry=https://gitlab.com/api/v4/packages/npm/ //gitlab.com/api/v4/packages/npm/:_authToken=$NPM_TOKEN

What could cause that? How can I have the same behaviour than my colleagues?

I tried with zsh and .zhsrc, with bash and .bash_profile too.

I tried with npm and yarn

Using quoted and unquoted export NPM_TOKEN="<token>"

Tried to remove the {} in my .npmrc

Tried with a .yarnrc file

Thank you for your help!
