poetry show fails to resolve private package with extras

[Agalin]

• 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: Windows 10, RHEL 7.8
• Poetry version: 1.1.0-1.1.2
• Simple pyproject.toml with a private repo:

[[tool.poetry.source]]
name = "private-repo"
url = "<repo url>"

[tool.poetry.dependencies]
python = "^3.6,<3.9"
private-dependency = {extras = ["extras"], version = "^1.20.35723", source = "private-repo"}

Issue

When running poetry show with a private package that has extras installed command fails with SolverProblemError.

For this package there are multiple extras, some with just public packages, some with mix of public and private. It doesn't matter which one is required, command fails even if only public packages are required by extras marker but succeeds if there are no extras specified to install.

Specifying extras for public packages doesn't break the command. Generating lock file from scratch (poetry lock) doesn't change anything.

Install, add, lock are working correctly for this dependency. Only show fails.

Version 1.0.10 works correctly.

  SolverProblemError

  Because private-package depends on private-dependency[extras] (^1.20.35723) which doesn't exist, version solving failed.
