windows - Certain NPM installs fail with EPERM 50 (Gulp and others) -

I have to continue allowing errors on Windows 7 when NPM is trying to install some modules. For example, the global installation of CALL is as follows:

I get this error when running CMD as an administrator. I have read in other such posts that it can represent an unavailable program. git is installed and works, so it is not so. Bover is installed and works; I have tried to add system path to c: \ windows \ system32 . No help. As you might be able to tell, I've modified the location of my NPM cache that maybe this folder was by default, there are no permissions problems, there is no help, or I - add no-bin-link option I have tried, I do not really help because of this loss, which is causing this problem is the only issue in trying to install slush-mongo , either world level On or locally

  npm config cache-lock-retries 1000 npm configuration set cache-lock-wait 100000   / pre>
