npm install error 4058, can't install private module in windows - node.js

Question

I can't install my private module call storage:0.1.1 when I command npm install in the root path.
I write package.json to install this module as:
"dependencies": {
"storage": "file:modules/storage"
}
And I also write package.json in the private module stroage already, it's work on my linux well, on windows well before, but one day I install occur error -4058
And there are error message:
909 verbose stack Error: ENOENT: no such file or directory, scandir 'C:\Users\vincent_lin\AppData\Roaming\npm-cache\storage\0.1.1\package.tgz'
909 verbose stack at Error (native)

919 error enoent ENOENT: no such file or directory, scandir 'C:\Users\vincent_lin\AppData\Roaming\npm-cache\storage\0.1.1\package.tgz'
919 error enoent This is most likely not a problem with npm itself 919 error enoent and is related to npm not being able to find a file.
920 verbose exit [ -4058, true ]
PS: I have tried to use powershell with administration and I checked the path
C:\Users\vincent_lin\AppData\Roaming\npm-cache\storage\0.1.1\package.tgz
is correct.
And I ever update npm to latest version, it still exist error.
Thanks for any response.

In Windows you must use \ slash and not / slash.
Please provide relative path starting with a .\
Eg: "dependencies": { "storage": "file:.\modules\storage" }
Or provide the full path starting with the drive letter.
