'poetry install' command fails; *.whl files are not found

I am managing dependencies in my Python project via Poetry.

Now I want to run this project in a machine which is different from my dev machine. To install dependecies, I simply run this command from the root directory:

$ poetry install

but then it raises the following errors:

Updating dependencies

It would be good to know what these *.whl are and how they are used by Poetry.

According to https://github.com/python-poetry/poetry/issues/4163, it seems to be an issue still pending to be resolved.

As a workaround, dumping dependencies to a requirements.txt file via poetry:

$ poetry export -f requirements.txt --output requirements.txt --without-hashes

and then installing them via pip, worked for me:

$ pip install -r requirements.txt

It seems to be related to poetry cache. For me, it works as intended if i go to User\user\AppData\Local\pypoetry and I delete the cache folder.

Specifically I found that deleting the AppData\Local\pypoetry\Cache\artifacts folder (I'm on Windows 10) worked for me. virtualenvs for other projects may be in AppData\Local\pypoetry\Cache\virtualenvs so you might not want to delete the root cache folder at AppData\Local\pypoetry\Cache in its entirety.

So it turns out I was missing visualstudio build tools as this question states.

https://docs.microsoft.com/en-us/answers/questions/136595/error-microsoft-visual-c-140-or-greater-is-require.html

I downloaded and installed it and everything works fine now.

For me the bug is gone with the latest poetry release >=1.1.12

So running poetry self update should fix it.

Fixed issue: https://github.com/python-poetry/poetry/pull/4549

1.1.12 poetry release: https://github.com/python-poetry/poetry/releases/tag/1.1.12
