Unknow missing dependencies

[Sergi Almacellas Abellana]

Hi,

When opening a tryton server I have the following error:

Traceback (most recent call last):
File "trytond/bin/trytond", line 80, in <module>
server.TrytonServer(options).run()
File
"/home/sergi/nan/projectes/virtualenv/tests/trytond/trytond/server.py",

line 191, in create_graph
- set((p[0] for p in packages))))
Exception: Missing dependencies: []

I have seen this error a lot of times but with a list of dependencies,
not with an empty list. So I'm wondering what could go wrong?

Have anyone found the same error? Any tip on how to fix?

Thanks in advance.

I droped database and restore with psql ago. And ok.... Misterious.

Finally I found the reason but not how to fix.

module_a -> extras depend -> module_b
module_b -> depends -> module_a

If remove extras_depend in module_a, I can create/update/start a database
In case I add extras_depend in module_a, get expecption on missing
list dependencies (and can't create/update/start a database)

Is it a bug?

For me it's a bug in the module, as the extras_depends of module_a is
wrong and this functionality should be implemented in module b.

Yes in your modules because you create a circular dependency.
