Thanks @i077. I saw this issue but can’t see how to apply it to my situation. In my pyproject.toml there are no exclude keys and the only thing that looks like a glob or path is README.md.
I made some new observations.
Observation 1: fresh pyproject.toml also doesn’t work
Recreating the pyproject.toml and poetry.lock without any dependencies doesn’t work:
$ nix develop
$ rm pyproject.toml poetry.lock
$ poetry init --no-interaction
This command will guide you through creating your pyproject.toml config.
You can specify a package in the following forms:
- A single name (requests)
- A name and a constraint (requests@^2.23.0)
- A git url (git+https://github.com/python-poetry/poetry.git)
- A git url with a revision (git+https://github.com/python-poetry/poetry.git#develop)
- A file path (../my-package/my-package.whl)
- A directory (../my-package/)
- A url (https://example.com/packages/my-package-0.1.0.tar.gz)
$ poetry lock

786│ suffix = parts[0]
787│ if not suffix.startswith('.'):
788│ raise ValueError("Invalid suffix %r" % (suffix))
789│ name = self.name
If I add the readme field to [tool.poetry] like this:
--- pyproject.toml
+++ pyproject.toml
@@ -3,6 +3,7 @@
version = "0.1.0"
description = ""
authors = ["Tad Lispy <tadeusz@lazurski.pl>"]
+readme = "README.md"
[tool.poetry.dependencies]
python = "^3.8"
I get the old error back:
$ poetry lock
TypeError

Setting readme = "./README.md" produces the Invalid suffix '' error again.
Observation 2: poetry from nixpkgs can build and run (!) migra
Like this:
$ nix shell nixpkgs#poetry
$ poetry build
Building migra (3.0)
- Building sdist
- Built migra-3.0.tar.gz
- Building wheel
- Built migra-3.0-py3-none-any.whl
$ poetry run migra
usage: migra [-h] [--unsafe] [--schema SCHEMA] [--exclude_schema EXCLUDE_SCHEMA]
[--create-extensions-only] [--with-privileges] [--force-utf8]
dburl_from dburl_target
migra: error: the following arguments are required: dburl_from, dburl_target
Notice that in this case I’m using nix shell with poetry instead of the development shell of the project (i.e. nix shell ... command instead of nix develop).
I really don’t know what to think about it.
