npm install EACCES error on windows

问题:

I've tried to run cmd as administrator, to change permissions on nodejs folder in Program Files, to login as Administrator, to runas /norprofile..., even to run command in safe mode. Always the same error when I run "npm install uglify-js".

C:\Users\user123>npm install uglify-js

Anybody have an idea how to solve this?

回答1:

After turn off the kaspersky, it can connect the server to download node modules

回答2:

As noted above:

The problem was with windows firewall which I was not aware it was turned on. Now I turned it off, and without any problems, npm installed desired package.

In my case, I get a similar error but for a Nodejs program that continuously connects to MongoLab (not just installing or updating a module)... so I added a Windows firewall exception specifically for Nodejs, and the host and port my program is connecting to.
