诗歌使用错误Python版本

Question

Trying to install packages using poetry And getting:

Current Python version (3.10.4) is not allowed by the project (>=3.8,<3.10).

Then I'm trying to do:

poetry env use python3.8

Or

poetry env use 3.8

And the same error popping. Any reason this could happen?

Answer 1

Make sure that when you are switching python version you are using a full path, so poetry has no problem with resolving the version:

poetry env use /usr/bin/python3.8

If that didn't help, check your pyproject.toml and make sure that the version of python is compatible, something like:

python = "^3.8"

If that's not the case try setting up global version:

pyenv global 3.8.15

Also, make sure that all the utility tools are compatible with expected python version:

sudo apt-get install python3.8-distutils
apt install build-essential libssl-dev libffi-dev python3-dev -y
