Error when installing via npm on Windows 8

[kyleect]

I'm getting an error when running npm install grunt-casperjs. That command outputs this error:

I am able to install other npm packages without error. Please see the log output below. I truncated to the end with the error as github has character limit.

I'm having the same problem.

I also noticed that the install said Casperjs wasn't installed and the error occured whilst attempting to install Casper. Thing is that I have Casper already installed and it never picked it up.

Any idea on a fix?
