I cannot install the microsoft/signalr package inside my Vue.js project.

Import

import signalR from '@microsoft/signalr';

Install Command:

npm install @microsoft/signalr

During runtime I get:

Uncaught Error: This is a placeholder package!

  • Are there any other packages you're referencing? Seems unlikely that it's related to the SignalR package. – Brennan Jun 03 '21 at 17:00

  • Unless the OP is using a very old version of NPM, [the `--save` option is no longer needed](https://stackoverflow.com/a/19578808/4468423). – Erich Jun 03 '22 at 14:42
