Silently fails to extract

[JonWallsten]

I'm using the module npm-cache and for some reason it won't extract the modules.
It however works for the bower modules.
This is the code used for both type of modules:

  var extractor = tar.Extract({path: targetPath})
                     .on('error', onError)
                     .on('end', onEnd);

  fs.createReadStream(cachePath)
    .on('error', onError)
    .pipe(extractor);

Cache path: C:\Users\***\.package_cache\npm\3.6.0\6cd7ceb02dc80477b9c0084e50507a72.tar.gz
Size: 115MB
Target path: C:\TeamCity\buildAgent\work\6e8ae23de4bcc9d9\***SE_src\***.SKT\***.SKT.Api\***.SKT.Api\Application

I'm have double checked the paths. They are both correct.
I'm using Windows 2012 Server.

I don't get any error message. Is the error handling applied correctly?
If so, how come I don't get any error?

I have tried to extract the file manually. It works and the structure is fine.

Turns out npm-cache had created an empty tar.gz in the C:\Users***.package-cache and didn't use the path i specified with "-.cacheDirectory". So I was looking at the wrong file the whole time. False alarm!
