Encountering an Unrecognized Token Error When Installing Angular Material from npm

Run in admin PowerShell:

npm fetch @ng-material-lib

Error: invalid token encountered. Also, attempting:

npm fetch @ng-material-lib/core

npm 3.9.5, node 6.2.2, Windows 7.

hey, try updatin node/npm and use ‘npm install @angular/material’ instead. sounds like package mismatch than a token error. maybe check if you have rights. cheers!

Upgrading both Node and npm resolved similar issues I experienced in the past. I found that using an older version sometimes leads to misinterpretation of package names, especially with scoped packages. Additionally, running commands as an administrator can sometimes help, but the underlying solution usually lies in using a more stable release of Node. I upgraded to a recent LTS version and used the official Angular Material package. This approach eliminated the token errors and improved overall package management reliability in my workflow. It might be worth trying if you haven’t yet.
