[BUG] npm install does not run prepare script for local file dependencies

[HosseinAgha]

What / Why

Imagine I have package-a that depends on the package-b using the file specifier.
For example we have this dependency line in the package.json of package-a:

"name": "package-a",
"dependencies": {
   "package-b": "file:../package-b"
}

How

Current Behavior

If I run npm install in package-a then npm correctly installs package-b dependencies.
But it only runs preinstall and postinstall scripts and ignores prepare script.
If I run npm install directly in package-b then it successfully runs the prepare script.

Expected Behavior

It should run prepare script for local dependencies (package-b) like it would for github dependencies. This gets very confusing for npm users as npm install would run inconsistent scripts for different dependency types.

References

I think #321 is related but it seems fixed in the latest version.

npm version

I use node v12.13.0 and npm 6.13.0

The same thing is happening to me. I also tried to install package-b in another project (npm install "../folder/package-a/package-b") and I got the same result: package is installed, but no prepare or prepublish script ran. Is this an expected behavior?

I have node v10.16.0 and npm v6.9.0.
