npm loads a version of a package (angularfire2) different from the one specified in package.json

I am trying to create a new development environment for an app using angularfire2 package, downloading the source code from a repository.

The package.json file points to version 2.0.0-beta.6 of angularfire2, as in the following snippet

{
  "name": "blah blah",
  "author": "blah blah",
  ...
  "dependencies": {
    ....
    "angularfire2": "^2.0.0-beta.6",
    ...
  }
  .....
}

I run npm install to download all the packages I need.

Unfortunately, in case of angularfire2, what gets downloaded seems to be a different version of the package (probably 2.0.0-beta.8) which has several breaking changes with respect to version 2.0.0-beta.6.

How is this possible?

The package.json file within the angularfire2 directory (under node_modules) is the following

{
  "_args": [
    [
      {
        "raw": "angularfire2@^2.0.0-beta.6",

}

The first breaking change (just to make an example that sustains my theory that this is a different version of the package) is that there is no more FirebaseAuth (which seems to be substituted by AngularFireAuth).

It's installing a later version, as that version satisfies the caret range you have specified in the package.json file:

"angularfire2": "^2.0.0-beta.6"

If you want a specific version, remove the caret:

"angularfire2": "2.0.0-beta.6"

Looking at the spec - under that NPM has filled out under _requested in the package.json file that's in node_modules/angularfire2 - you can see that caret range you have specified is equivalent to:

"spec": ">=2.0.0-beta.6 <3.0.0",
