Sub-package path dependencies don't work

[carlor]

The following dependencies:

        "dependencies": {
                  "vibe-d": {"path": "../vibe.d"}
        }

With vibe-d master in ../vibe.d leads to the following error message:
Unknown dependency: vibe-d:core

Try the following things :

• dub clean-caches
• remove dub.selection.json from the project directory
• remove global DUB state in .dub directory (C:\Users\$USER\AppData\Roaming\dub on Windows).
  This solves such problems here.

If it's not caused by locally cached information, which version of DUB is this? It works for me with GIT master.

[carlor]

It worked by removing dub.selection.json

[s-ludwig]

Do you have the old dub.selections.json file still lying around by chance? Would be interesting to see if the error has been legitimate or if it could be improved. But I haven't been able to reproduce it, so without more information I guess this can be closed.

Here's how I reproduced it:

1. First create vibe project: $ dub init proj -t vibe.d; cd proj
2. Run: $ dub run
3. dub.selections.json now includes "vibe-d": "0.7.26"
4. Change dub.json to have "vibe-d": {"path": "../vibe.d"}
5. dub.selections.json hasn't changed, so dub run fails.
6. Remove dub.selections.json,
7. Now it works.

Should dub.selections.json be removed every time dub.json changes?

[s-ludwig]

No, that's a bug. It should still pick 0.7.26, since it's listed in dub.selections.json, but output a warning "vibe-d 0.7.26 doesn't match dependency specification path=../, do you need to 'dub upgrade'" or similar. I'll have a look.
