`extras_require` ignores version specifier

• 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).

• OS version and name: MacOS 10.15
• Poetry version: 1.1.2
• pyproject.toml / setup.py: https://gist.github.com/Fizzadar/a1b98304a2b86ee966dedea6479320bd

Issue

The extras_require in the generated setup.py ignores the version specified in the pyproject.toml, leading to inconsistent/broken builds when installing a package with extras.

Gist above contains full info, but specifically:

[tool.poetry.dependencies]
kombu = {version = '^=4.5', optional = true}

[tool.poetry.extras]
queue = ['kombu']

Becomes:

extras_require = \
{'queue': ['kombu']}

@Fizzadar you can add the following to your pyproject.toml to avoid this altogether. Poetry will stop generating setup files by default in coming release.

[tool.poetry.build]
generate-setup-file = false

This issue is a big misunderstanding, the actual problem is this bogus version ^=4.5

if you replace that with ^4.5 which is presumably what was intended then the requirement comes out as 'kombu>=4.5,<5.0'.

so it would still be nice if poetry rejected the bad version rather than somehow interpreting it as being *: but that’s the real problem.
