digitalmars.D.learn - dub: Could not resolve configuration for package demo

Very simple thing from https://dub.pm/getting-started/first-steps/

After I add dependencies, it cannot build:

```
$ cat dub.json
{
         "authors": [
                 "mw"
         ],
         "copyright": "Copyright © 2024, mw",
         "description": "msgpack-rpc-d demo.",
         "license": "MIT",
         "name": "demo",
         "dependencies": {
                 "msgpack-rpc": "~>0.1.3"
         },
         "subConfigurations": {
                 "msgpack-rpc": "default"
         }
}

$ dub build
Could not resolve configuration for package demo
```

So what I'm missing?

Thanks.

Trying to build your dependency msgpack-rpc, it spits out
```
      Warning The sub configuration directive "vibe-d" -> 
[libevent] references a configuration that does not exist.
Error Could not resolve configuration for package msgpack-rpc
```
In version 0.7, vibe-d depended on libevent, this got removed in 
the meantime
https://github.com/vibe-d/vibe.d/commit/196096407ec27b2c107f0038c6751ce07e7a9507

Just patching msgpack-rpc dub.json to use the exact vibe-d 
version, and not a minimum, like this
```json
	"dependencies": {
		"msgpack-d": ">=0.9.2",
		"vibe-d": "==0.7.25"
	},
```
fails too, because this old vibe-d version doesn't compile 
anymore.

You'll have to either fix the old vibe-d version, or fork 
msgpack-rpc to work with current vibe-d, whatever is more 
appropriate and easier.

Thanks for the reply.

But where you see this warning message? I didn't see it even with 
`$ dub build -v`.

I'm trying to fix it with the latest vibe-d 0.10.0, now the new 
error:

```
../../src/msgpackrpc/transport/tcp.d(13,8): Error: unable to read 
module `driver`
../../src/msgpackrpc/transport/tcp.d(13,8):        Expected 
'vibe/core/driver.d' or 'vibe/core/driver/package.d' in one of 
the following import paths:

```

that line is:

```
import vibe.core.driver;
```

Do you know where is `vibe.core.driver` in the new version?

OK, looks something wrong with dub / or vibe-d 0.10.0

https://github.com/msgpack-rpc/msgpack-rpc-d/blob/master/examples/with_http_server/dub.sdl#L5

with
```
dependency "vibe-d" version="~>0.7.25"
```

`dub build` can at least starts.

But

```
dependency "vibe-d" version="~>0.10.0"
```


```
$ dub build
Error Could not resolve configuration for package with_http_server

```
