Poetry 1.0.6 fails to install another poetry project from a sub-folder

[graffic]

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Archlinux
• Poetry version: 1.0.6

Issue

The pyproject.toml file has a dependency on another poetry project. But it seems after poetry install, it fails to install. This was working with 1.0.5. If I go to the schemas folder and execute a poetry install inside the virtual-env, I can install the main package afterwards.

Output I get

Package operations: 1 install, 0 updates, 0 removals

  - Installing ovat-schemas-metrics (0.6.0 schemas)
  - Installing metrics (0.20.0)

[EnvCommandError]

What's the structure of both you projects?

[graffic]

I just published a small example here: https://github.com/graffic/poetry-106-issue

poetry install will finish in 1.0.5

I found the root cause. I will fix it and make a new release.

Thanks!
