Sails.js won't install. Windows

Question

Sails.js will not install, but just to make sure npm is working I installed grunt npm install -g grunt-cli and it installed correctly.

But when I run npm install -g sails I get an error.

Command prompt error:

`sails@0.11.0 preinstall C:\Users\User\AppData\Roaming\npm\node_modules\sails node ./lib/preinstall_npmcheck.js

Sails.js Installation - Error

Please reinstall npm to use Sails.js

Answer 1

I got the same errors.

npm -g install sails

But it worked when I ran command line as administrator.

Answer 2

I solved this by running npm install -g sails --ignore-scripts. The only thing I can think of is for some reason I don't have ./lib/preinstall_npmcheck.js file and it is trying to run it, so by ignoring it I don't get the error, hence the successful install. I still don't understand why, but I hope this helps someone.
