Poetry: Installing `scrapy`: maximum recursion depth exceeded while calling a Python object

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

• OS version and name: Linux Mint 20
• Poetry version: 1.0.10

Issue

I'm trying to install scrapy, but getting:

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

With -vvv I see:

0: Duplicate dependencies for lxml
0: Different requirements found for lxml (>=3.5.0) and lxml (>=4.0.0).

It seems it happens because of latest setup.py

Hello @dmiwell,

could you try it with the latest preview release of poetry? With this I'm not able to reproduce your problem.

Hi @finswimmer

Thanks for the quick response. I can confirm that it works fine with Poetry version 1.1.0b2
