poetry does not resolve dependencies correctly for fastdiff #3140
Description
- 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 (
-vvvoption).
- OS version and name: macos 10.14
- Poetry version: 1.1.2
- Link of a Gist with the contents of your pyproject.toml file:
[tool.poetry]
name = "code6"
version = "0.1.0"
description = ""
authors = ["sobolevn <[email protected]>"]

fastdiff = "0.2.0"

Take a look at this part:
[[package]]
name = "fastdiff"
version = "0.2.0"
python-versions = "*"
[package.dependencies]
wasmer = {version = ">=0.3.0", markers = "python_version >= \"3.5\" and platform_machine == \"x86_64\" and sys_platform == \"darwin\""}
That's how poetry resolves deps for fastdiff. And there's how they are defined:
requirements = [
# wasmer, if we are in Linux x86_64
'wasmer>=0.3.0; python_version>="3.5" and platform_machine=="x86_64" and sys_platform=="linux"',
# wasmer, if we are in macOS x86_64
'wasmer>=0.3.0; python_version>="3.5" and platform_machine=="x86_64" and sys_platform=="darwin"'
]So, I end up with a missing wasmer package on linux. PR with reproduction: wemake-services/wemake-python-styleguide#1655
