poetry sync will not switch package from non-editable to editable

[wdhwg001]

Description

Please let me know if this needs to be split into two issues.

I have some packages that is deep editable. It means:

Package A has a develop = true dependency, which is Package B.

Package B has a develop = true dependency, which is Package C.

I notice that when creating venv for Package A, Package C is not installed as an editable pip dependency.

Workarounds

The only workaround is to explicitly add Package C as a develop = true dependency of Package A. But after running poetry lock and poetry sync, nothing really happens, and I have to manually remove the package using pip and sync again.

You forgot to provide the details that the issue template asks for

However this sounds expected, and duplicate eg #10178

Please let me know if this needs to be split into two issues.

If I understand correctly, your first issue is

Package A has a develop = true dependency, which is Package B.

Package B has a develop = true dependency, which is Package C.

I notice that when creating venv for Package A, Package C is not installed as an editable pip dependency.

The only workaround is to explicitly add Package C as a develop = true dependency of Package A.

That is #10178 or #10683 (which is newer but has some additional information).

Your second issue (the main issue according to the issue title) is:

But after running poetry lock and poetry sync, nothing really happens, and I have to manually remove the package using pip and sync again.

There is probably already an issue for that but I cannot find it at the moment.
