• 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 (`` option).

• OS version and name: Mac Catalina darwin
• Poetry version: 1.0.5
• Link of a Gist with the contents of your pyproject.toml file:

[RecursionError]
maximum recursion depth exceeded while calling a Python object

I was able to pinpoint problem to this

Duplicate dependencies for ipykernel
   0: Different requirements found for ipykernel (*) and ipykernel (>=5.1.3).
   1: Version solving took 0.029 seconds.
   1: Tried 1 solutions.
   0: Retrying dependency resolution for Python (>=3.8,<4.0).

which was caused by spyder-kernelsrequirements

REQUIREMENTS = [
  ...
    'ipykernel',
    'ipykernel>=5.1.3; python_version>"2"',
  ...
]

after removing first ipykernel I was able to install spyder-kernels from my fork

Fixed in 1.1.0b2. Requires regeneration of lock file. Note that new lock file is not compatible with older versions of poetry.
