Now, I try to install dub from the official repo.
Then I do

* dub init server -t vibe.d
* cd server
* dub

I hit this issue : https://github.com/dlang/dub/issues/1712

As suggested, i try to build dub from github, following: 
https://github.com/dlang/dub/releases

I call ./build.d - and everything stops, and machine crashes.

I then try to install DaNode: 
https://github.com/DannyArends/DaNode

It breaks with : module std.algorithm import 'mean' not found

Then I try to install the Hunt Framework. It breaks with : basic 
type
expected, not foreach


Please help. I really want this issue to be resolved-

I don't know if it is a solution. But you can try using ~master 
branch, not a release on GitHub.


You can also try my vibed app skeleton:
https://github.com/aferust/simplerestvibed
İ simply run it with dub command.

How is your network connection to the dub server? Maybe there is a 
separate problem with network connectivity.

This thing works for me (dub upgrade takes about 2.5 seconds and 
finishes). How long does it take for your process to give up?

In any case, maybe the dub check to see if it's "taking too long" needs 
to take into account progress that is being made (a "pathalogical case" 
suggests it's not making progress).

With dub 1.18 more than 5 minutes.

If i use dub search dub, it finishes in seconds.

dub fetch dub is fine too.

dub run dub takes 10-12 seconds, and throws the same dependency

Hey Seany,

A quick follow up post. I think/suspect that something might be 
broken in your dub installation if the mean import is not found. 
This is the first import from the phobos standard library in the 
project.

Could you try compiling the DaNode web server without using dub ?

git clone https://github.com/DannyArends/DaNode.git
cd DaNode
rdmd danode/server.d -p=8080

This should work, when you have a working D+Phobos standard 
library installation. If this throws error of being unable to 
find the canFind import (now the first one) then somehing in your 
dub/dmd installation is broken and you will probably have to 
reinstall dmd+dub

Kind regards,
Danny

then dub showed the error : out of memory.

I applied: dub --build-mode=singleFile

That seems to work

Hey Seany,

DaNode author here, the mean function is only used to compute 
some server statistics. I am sorry to hear it didn't compile out 
of the box with the latest DMD compiler, I only tested up-to 
2.088.0

I just installed the latest version 2.090.0 but also using this 
version it compiles fine. Looking into the dlang docs it seems it 
was moved from std.algorithm to std.algorithm.iteration, I wonder 
why it doesn't find this function.

However I just added a mean function to the web server since it 
should always find this function.

Could you pull the latest master branch and try compiling it 
again ?

dub -- -p=8080

then see if the web server works by navigating to

http://localhost:8080/

let me know if you run into any other issues

Kind regards,
Danny

Sample code:
```
import hunt.http;

void main()
{
     HttpServer server = HttpServer.builder()
         .setListener(8080, "0.0.0.0")
         .onPost("/", (RoutingContext context) {
             context.end("Hello World!");
         })
         .onGet("/user/:name", (RoutingContext ctx) {
             string name = ctx.getRouterParameter("name");

             ctx.write("Hello " ~ name);
             ctx.end();
         })
         .build();

     server.start();
}
```


(hunt-framework based):
```bash
git clone https://github.com/huntlabs/hunt-skeleton.git myproject/
cd myproject/
dub run -v
```

You can Add pages in `config/routes` , like this:
```
GET   /   index.index
GET   /user/{name}    user.detail
```

Add Controller file `controller/UserController.d` :
```
module app.controller.UserController;

import hunt.framework;

class UserController : Controller
{
     mixin MakeController;

      Action
     string detail(string name)
     {
         return "Hello " ~ name;
     }
}
```

Build and run it:
```
cd myproject/
dub run -v
```

You can see it in the borwser:
```
http://localhost:8080
```

How much memory does this machine have? Is it a virtual machine 
provided by a hosting company? My suspicion is that your server 
is very slow for some peculiar reason.
