First start command prompt as an administrator then run your command.

I had a similar issue which was caused by a corrupt download.

It was easily solved by purging the offending package from the cache and re-running the installation.

$ npm cache clean express
$ npm i express

(in my case the corrupt package was a dependency, so I purged it from cache, and not the package that I was trying to install, of course)

Some of these error messages will typically come up when you are not accessing the root admin of the system while executing the install.

When I opened the terminal and ran $ sudo -i to access the #root and then entered $ npm install express , it was installed correctly. Hopefully this helps!
