I've installed Webpack through NPM in my ASP.NET core Web project. And now version of webpack is: `2.4.1`. However, I need to install the following version of webpack: `2.1.0-beta.25`.

I've tried to use the following command:

```
npm install webpack@2.1.0-beta.25

```

But it seems that this command is not installed a desired version of Webpack cause this command `npm view webpack version` shows: `2.4.1`

How can I downgrade to `2.1.0-beta.25`?
