Before there are times this, thought it is really not enough permissions, feel a little strange, with administrator rights to perform, sometimes really useful, but later checked, when the cache problem, clean up the cache on the line, without administrator rights.

Method 1.

You need to delete the npmrc file.

Emphasis: not the nodejs installation directory npm module under the npmrc file

but in C:\Users\{account}\ under the .npmrc file …

Method 2.

Or just clean it up directly with the command, console type.
