Unable to install appium through npm

I'm receiving the following error in npm when I run the "npm install -g appium" in OSX terminal

npm ERR! Darwin 16.0.0
npm ERR! argv "/usr/local/Cellar/node/7.2.0/bin/node" "/Users/myUsername/.npm-packages/bin/npm" "install" "-g" "appium"

Can anyone help me out of this?

This is an issue with npm. I downgraded npm to npm@3 from 4 and it worked for me.

I have a very similar issue (and I tested with npm@3 and npm@4), notice this problem only happens when I use a virtual macOS (macOS sierra in this case):

@harikrishnaburma: Did you manage to fix it ???

FYI:

@plozachmad Yes. I fixed it by a downgrade.

Will there be a fix from Appium for this? I need to be on the latest npm. Thanks kindly.
