Unable to retrieve the package version for git on preview 1.1.0b2

[serjflint]

• 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: Linux 5.7.11-1-MANJARO
• Poetry version: 1.1.0b2
• Link of a Gist with the contents of your pyproject.toml file: https://gist.github.com/serjflint/dfbb4bc8293ebce28b256aa53c22c8ac

Issue

I need the preview build for solving another bug. But now git packages are not working.
Works as intended on the latest release 1.0.10.

[abn]

@serjflint the issue here is caused by:

https://github.com/python-trio/triopg/blob/19343c5012d43219999e983d03f31e9bdd9415f1/setup.py#L3

Since the version is determined dynamically, we are unable to inspect the version from the file.

Can you try poetry from the master branch? We have an improvement that might address this issue.

[serjflint]

@abn How to install poetry from source? I didn't find it in the docs

[abn]

If you used the installation script, then you'd want to uninstall before this.

Otherwise, pip install --user git+https://github.com/python-poetry/poetry.git should do the trick.

[serjflint]

@abn master branch didn't solve the problem and added new messages:

1.0.10 works with that repo though

[abn]

@serjflint that one is due to a bug in the pre-release version with respect to parsing ~=. You can test the fix by also installing poetry-core from master too in the same site as poetry install.

[danihodovic]

I'm still facing the same problem with the install from git master.

[abn]

@danihodovic this requires poetry-core from master. Just confirming you tested with that, not just poetry from master.

[rotu]

I'm having the same issue and it does not appear resolved by installing poetry-core from master:
