Question: I just bought a deno.js course from udemy. The installation was done perfectly but when running a script through deno. It shows an error 'cannot resolve module //filepath'. But when tweaking the path it works perfectly. Here is the code and terminal code below:-

```

//JAVASCRIPT

function a(){
    console.log(1243);
}
a();

```

```

//TERMINAL

PS C:\Users\Intex> deno run deno.js                  
error: Cannot resolve module "file:///C:/Users/Intex/deno.js"         //ERROR

PS C:\Users\Intex> deno run C:\Users\Intex\Desktop\deno.js            //SUCCESSFUL
1243

```

Answer: 
I just had the same issue, I believe it's to do with the name of the file. I changed it deno\_demo.js and it worked fine without having to specify the absolute path.
You need to provide the relative path of the file with the run command from where you are running the command in the terminal. You can also provide the absolute path. Please take care of forward/backward slashes in the path depending upon the os you are using
