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).

Issue

I am trying to add the responder dependency on Windows. Notice that their setup.py specifies that the uvloop dependency should not be included on Windows, as it is incompatible. However, it seems that Poetry is attempting to install it anyways:

PS Z:\sudiamanj\playground> poetry add responder
Using version ^1.1 for responder

Resolved in uvicorn v 0.4.6 by PR https://github.com/encode/uvicorn/pull/309

Uvicorn 0.5.* is likely to use extras (see https://github.com/encode/uvicorn/issues/219) to cover this issue so things can break or change again in some situations (hopefully get finally resolved).
