I was struggling with the same as OP and I figured out that the hashes were cached so i deleted /.cache/pypoetry/ along with my poetry.lock and then it worked. EDIT: this was debian

above solution don’t work for me

the op of this thread found the error when installing bokeh and possibly other package as well, but i can recreate it from empty project

• OS version and name: ubuntu 21.10
• Poetry version: 1.1.11
• Link of a Gist with the contents of your pyproject.toml file:

1. create empty project with poetry

pyproject.toml

[tool.poetry]
name = "temp"
version = "0.1.0"
description = ""
authors = ["author <[e-mail]>"]

[tool.poetry.dependencies]
python = "^3.9"

[tool.poetry.dev-dependencies]

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

1. poetry add flask-admin

3. i try to uninstall with get-poetry --uninstall

uninstall

$ python3 get-poetry.py --uninstall
# We are sorry to see you go!

This will uninstall Poetry.

It will remove the `poetry` command from Poetry's bin directory, located at:

$HOME/.poetry/bin

This will also remove Poetry from your system's PATH.


Are you sure you want to uninstall Poetry? (y/[n]) y

4. but after i check poetry command, it is still installed so i just remove symbolic link

$ which poetry
/home/r3r/.local/bin/poetry
$ ll ~/.local/bin/poetry
lrwxrwxrwx 1 r3r r3r 47 Nov  7 12:26 /home/r3r/.local/bin/poetry -> /home/r3r/.local/share/pypoetry/venv/bin/poetry
$ rm ~/.local/bin/poetry
rm: remove symbolic link '/home/r3r/.local/bin/poetry'? y
$ poetry --version
poetry: command not found

1. reinstall as suggested above

2. when i try poetry add flask-admin, the same error on 2 happen again

---

temporary solution 1 : poetry run pip install flask-admin

but flask-admin have to be installed everytime you run poetry install

temporary solution 2: edit executor.py

on my case it is on ~/.local/share/pypoetry/venv/lib/python3.9/site-packages/poetry/installation/executor.py

so i edit based on this comment https://github.com/python-poetry/poetry/issues/4701#issuecomment-963712002

archive.name if hasattr(archive, 'name') else archive.filename,

this is little bit different with recent poetry code

but i got another error

this is another error not related to this issue, but i still can’t find if there is issue similar to this

so in the end i use temporary solution 1 for flask-admin

---

there is some solution for this issue here https://github.com/python-poetry/poetry/issues/4085, but i can’t find which one fit for me yet without using temporary solution 2 to get RuntimeError
