Unable to use npm-upgrade on private registry - error E401 authorization required

[fasenderos]

Hi, I have set in the .npmrc of my progect the authentication to my private registry //private_registry.example.com/:_authToken=${NPM_TOKEN} and in the .env file NPM_TOKEN="MY_SECRET_NPM_TOKEN" .

I have also the authentication setted in the global .npmrc in C:\Users\myusername with //private_registry.example.com/:_authToken="MY_SECRET_NPM_TOKEN"

Infact I can run npm install without problem, but when I run npm-upgrade I get this error:

HttpErrorAuthUnknown: Unable to authenticate, need: Basic, Bearer

Nevermind, solved by creating a .bashrc file in my home directory C:\Users\myusername with export NPM_TOKEN="MY_SECRET_NPM_TOKEN" as suggested here.
