Ruby

The $ gem server command is broken. The gemserver doesn’t find the stylesheets and javascripts, so that the browser only shows the unstyled, bare HTML.

Sample commandline session:

% gem list ffi

Output of $ gem -v: 2.4.5.1

Notice the 404 errors when the web page is accessed. Expected behaviour is to correctly serve the CSS and JS files at the path where the documentation references them.
