Build fails on requirements.txt schema not followed correctly

[kenyerman]

Current Behavior

Since python-poetry/poetry-plugin-export#258 was merged, the temporary requirements.txt format's changed. This makes local project dependencies unparseable, making the build fail.

No response

Additional Information

The error is in:
packages/nx-python/src/executors/build/resolvers/locked.ts:67

strategy of parsing local dependencies from requirements.txt must be rewritten.

Workaround

downgrade poetry-plugin-export to 1.7.1

poetry self add  poetry-plugin-export@1.7.1

[kenyerman]

the issue can be also resolved by setting the develop=true to false for the dependency in the pyproject.toml

    [tool.poetry.dependencies.mylib]
    path = "../../../libs/mylib"
-   develop = true
+   develop = false

[lucasvieirasilva]

@kenyerman thanks for reporting this issue, well, the problem with the develop=false setting is that you need to build your local dependency to reflect the changes in the project that you are referencing, the develop=true creates an link between the projects.

I'll work on this poetry-plugin-export 1.7.1> support.

#207 solves this issue, confirmed.

Thanks for the very quick support!
