`ImportError: No module named entry_points_selectable`

• 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).

• OS version and name: Ubuntu 20.04 LST
• Poetry version: 1.1.8 -> 1.1.11

Issue

I have been to make a new repository but I got this issue with any command of poetry.

Same bug. Uninstalling and re-installing with

curl -sSL https://install.python-poetry.org/ | python3 - 

worked for me.

For convenience, if you installed poetry via get-poetry.py you can uninstall with:

curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python - --uninstall

@TinDang97 try uninstalling Poetry (assuing you used the get-poetry.py script) and then using the following command to install Poetry. Looks like you installed it under python 2.7, which is no longer supported.

curl -sSL https://install.python-poetry.org/ | python3 - 

Alternatively, you can install poetry using pipx.

pip install pipx
pipx install poetry
