Dependency resolving problem by Poetry

[jiangjun0105]

Expected Behavior

Poetry should be able to install this lib.

Current Behavior

but it gives error:

Because moto (1.3.13) depends on botocore (>=1.12.86)                                                                                                                                                           
   and pysqs-extended-client (0.0.1) depends on botocore (1.10.80), moto (1.3.13) is incompatible with pysqs-extended-client (0.0.1).                                                                             
  And because pysqs-extended-client (0.0.1) depends on moto (1.3.13), pysqs-extended-client is forbidden. 

Failure Information (for bugs)

see above

Steps to Reproduce

1. install poetry
2. add pysqs-extended-client = "*" to [tool.poetry.dependencies]
3. run poetry install

Context

python 3.8
mac intel chip

My guess

pip install can install it successfully probably it ignore dependency moto which is not used actually?
If moto is not really used, removing it can solve the problem.
