Root project not installed in editable mode

[Badg]

• 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).

Encountered on:

• OSX 12.2.1 @ poetry 1.1.12
• debian slim 11.2 (docker) @ poetry 1.1.13

Gist of pyproject.toml and dockerfile here

Issue

I can't get my root project installed in editable mode. My understanding (from both docs and past usage) is that the root project should always be installed in editable mode, but both within a docker container and on the host, I'm unable to get it to do so. I've tried removing the build system from pyproject.toml on the off-chance that it might be related to #2956, but that didn't get me anywhere (I also noticed #1382, but I don't know how this would be related). I also tried manually specifying it as an editable install in dev dependencies using develop = True, but that errored out on an assertion, so I... well, I basically gave up pursuing that route because it's been a long day.

Any thoughts? (PS: poetry is 🎉 😄 )

I think maybe i know why editable no working.

This module create .pth file to sites-packages to add local project directory to sys.path.
masonry/builders/editable.py

try:
            pth_file = self._env.site_packages.write_text(
                pth_file, content, encoding="utf-8"  # it use utf-8 for encoding
            )
            self._debug(
                f"  - Adding <c2>{pth_file.name}</c2> to <b>{pth_file.parent}</b> for"
                f" {self._poetry.file.parent}"
            )
            return [pth_file]

but it use utf-8 for encoding the .pth

In Lib\site.py which for process the .pth file to add user path to sys.path.

  def addpackage(sitedir, name, known_paths):
      """Process a .pth file within the site-packages directory:
         For each line in the file, either combine it with sitedir to a path
         and add that to known_paths, or execute it if it starts with 'import '.
      """
      
      if known_paths is None:
          known_paths = _init_pathinfo()
          reset = True
      else:
          reset = False
      fullname = os.path.join(sitedir, name)
      _trace(f"Processing .pth file: {fullname!r}")
      try:
          # locale encoding is not ideal especially on Windows. But we have used
          # it for a long time. setuptools uses the locale encoding too.
          f = io.TextIOWrapper(io.open_code(fullname), encoding="locale")
      except IOError:
          return

It use 'local' to decode .pth file.
so when our project path has local character and not asic2
it will get wrong path just like 'c:/锘挎槬鐪犱/锘'
and this path is not exists

@Badg It looks to me like your pyproject.toml is missing a required key -- eg, see here for an example of how it works in the current master.

This is from a project of mine that installs the project under development in editable mode in 1.1.13:

[tool.poetry]
name = "my-package"
version = "0.1.0"
description = "This is my package"
authors = ["anthonymichaelclark"]
include = ["my-package"]

Does adding that include key to your pyproject.toml solve your issue?

[abn]

@anthonymichaelclark I think you are looking for package keyword and not include. The latter is for additional files like data files, build files, tests etc.

@Badg it might be related to package specification as the above comment alluded to. Can you share the directory structure of the project?

You could also check what paths are being written into the my_package.pth file in the site-packages directory in your virtual environment.

I'm super busy at the moment, so I can't right now, but I'll try to get around to the above suggestions in the next few weeks!

Update on this: I still haven't had a chance to try this again at work. However, I just encountered the same issue on my personal computer -- a win10 box -- running on the host OS (ie no docker) with python 3.9 (poetry latest version, running on py3.10). There, my pyproject.toml looks like this (lol on the project name)

[tool.poetry]
name = "finfuck"
version = "0.0.1"
description = "Financial fucking bullshit"
authors = ["Your Name <you@example.com>"]

[tool.poetry.dependencies]
# Currently pdftopng (camelot dep) has no wheels for 3.10
python = "~3.9"
forex-python = "^1.8"
alpha-vantage = "^2.3.1"
camelot-py = {extras = ["base"], version = "^0.10.1"}

[tool.poetry.dev-dependencies]
pytest = "^7.1.1"
ipython = "^8.2.0"

[build-system]
requires = ["poetry-core>=1.0.0"]
build-backend = "poetry.core.masonry.api"

@anthonymichaelclark @abn I tried adding both packages and include to pyproject.toml and there was no difference in behavior. So it doesn't appear that the problem is there.

That being said, @kaluluosi 's comment about unicode definitely got my ears to perk up, because both my personal PC and my work computer have their system locale set to DE-DE.

When I go to remove the file, I also see:

PS D:\Dropbox\Projekte\finfuck> poetry run pip uninstall finfuck 
The currently activated Python version 3.10.0 is not supported by the project (~3.9).
Trying to find and use a compatible version.
Using python3.9 (3.9.7)
Found existing installation: finfuck 0.0.1
Uninstalling finfuck-0.0.1:
Would remove:
c:\users\niklas\appdata\local\pypoetry\cache\virtualenvs\finfuck-hb6y0nli-py3.9\lib\site-packages\finfuck-0.0.1.dist-info\*   
c:\users\niklas\appdata\local\pypoetry\cache\virtualenvs\finfuck-hb6y0nli-py3.9\lib\site-packages\finfuck.pth
Proceed (Y/n)?    

So it looks like the .pth is in fact being created.

Closing as a specialized duplicate of #6091 as the only working reproductions are based on that root cause.
