npm ERR! code E401 npm ERR! Unable to authenticate, need: Bearer authorization_uri=https://login.windows.net/72f988bf-86f1-41af-91ab-2d7cd011db47, Basic realm="https://pkgsprodcus1.pkgs.visualstudio.com/", TFS-Federated

  • Add a list of packages that you are trying to install. You can get the list from `package.json`. It seems like you are trying to install a private package and you don't have the necessary authentication – Ramtin Jun 28 '21 at 09:51
  • Are you trying to install packages from private repository ? – thug_ Jun 28 '21 at 10:23

I was facing a similar issue and this got fixed by running the below command. Run the below command to remove the default registry

npm config set registry https://registry.npmjs.org/

or

npm config delete registry

NPM CONFIG DOCS
