Could not parse version constraint: ~3.6.*

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

• OS version and name: Windows10
• Poetry version: 1.0.9

Issue

I initialized a project and tried to install index.py using poetry add git+https://github.com/abersheeran/index.py@setup.py.

➜ poetry add git+https://github.com/abersheeran/index.py@setup.py -vvv
Using virtualenv: C:\Users\AberS\Documents\**********************\.venv

On https://github.com/abersheeran/index.py/tree/setup.py, you can see that setup.py is automatically generated using dephell, and I have read that ~3.6.* does not appear, I don’t know the cause of this error.

Hope someone can help me. 😭

Which version constraint to you want to express? It looks like you are trying to mix tilde requirements and wildcard requirements which seems to not be supported.

[abersheeran]

This is the problem, I did not find any string similar to ~3.6.* in setup.py. @atollk

[abersheeran]

Which version constraint to you want to express?

~3.6

[atollk]

And what does your pyproject.toml look like?

[abersheeran]

There is no pyproject.toml, only a setup.py file.

[atollk]

I see. I guess it refers to this then: python_requires='==3.*,>=3.6.0'.

The usual way to express this constraint would be >=3.6,<4. Would you still receive the same error with this constraint?

[abersheeran]

The problem lies in the python version constraints of contextvars. python_version == "3.6.*" and python_version >= "3.6.0" is incorrectly parsed as "~3.6.*"
