npm unpublish support ?

[radenui]

Hi there,

I have trouble with npm unpublish command.
It returns me something like the following (traces of npm-register included):

npm unpublish [email protected]

Of course, the version exists...

npm view [email protected] version
0.14.0-dev.945

Is this command supported ?

Thanks !
