"Start a Minimal web server" example do not work.

[BoQsc via Digitalmars-d-learn]

This is the code example, that was presented on the 
https://dlang.org frontpage:

-----------------
#!/usr/bin/env dub
/+ dub.sdl:
name "hello_vibed"
dependency "vibe-d" version="~>0.8.0"
+/
void main()
{
    import vibe.d;
    listenHTTP(":8080", (req, res) {
        res.writeBody("Hello, World: " ~ req.path);
    });
    runApplication();
}
-----------------

I have copied this example code into start_minimum_server.d file.
Ran it as script with rdmd.exe

And got an output:
--------------------------

C:\Users\Vaidas\Desktop>rdmd start_minimum_server.d

'vibe\d.d' which cannot be read
