Can't install Fastdup using Poetry

[kikohs]

Hi, I'm trying to install your package with Poetry (package manager) on WSL (ubuntu) with Python3.8 but it fails :(.

I tried the regular way: poetry add fastdup

  • Installing fastdup (0.180): Failed

  RuntimeError

  Unable to find installation candidates for fastdup (0.180)

This is what I get when I tried to add from git directly

poetry add git+https://github.com/visual-layer/fastdup.git#main

Please let me know if there is something I can do. Thanks.

Hi @kikohs thanks for trying us on windows! We would love to help. We never used poetry before. Can you try and install inside the WSL terminal

python3.8 -m pip install -U pip
python3.8 -m pip install fastdup

And let us know if this works?

[kikohs]

It works! This is how I use it as a fallback but it doesn't get versionned so it is less portable as an install (you need a post-init script) manually triggered by the user.

[dbickson]

We will take a look into poetry to see how difficult it is to support. Thanks for your feedback, feel free to reach out for any issues!

Hi, @dbickson, do you have any updates on how to install correctly using Poetry?

I tried to install it using Poetry and encountered the error below:

  • Installing fastdup (1.42): Failed

  RuntimeError

  Unable to find installation candidates for fastdup (1.42)

[dbickson]

HI @jdonini please give us more information, which operating system, which python, did you upgrade pip, what is the output of pip debug --verbose on your system

[jdonini]

Sorry about my delay, I using Python 3.11.5, and pip 23.2.1.

The output of the Poetry is:

@jdonini , I think we don't have support for Python 3.11 yet. Can you try changing your Python version to 3.10?

Here are the steps that works for me.

mkdir fastdup_poetry
cd fastdup_poetry
poetry new .

Make sure Python version is < 3.11 in the pyproject.toml file. Here's mine for example.

[tool.poetry.dependencies]
python = ">=3.10,<3.13"

Run

poetry lock
poetry install
poetry add fastdup

Let me know if it works.

[jdonini]

It works when I change my local Python version using Pyenv to 3.10. If I use a global Python version (3.11.5), I get the same error, but in general, it works. Thanks.
