Errors when installing gulp-imagemin

Question

When I try to install gulp-imagemin in bash using the command npm install gulp-imagemin --save-dev I get a whole lot of errors as shown below. This is my first time using gulp (or a build tool). I have installed several other plugins and ran them fine. This is the first error I have seen. I am running Windows Vista. Thank you in advance.
