Poetry downgrade breaking Python on p3.9/n12

[ericboucher]

Hi @nikolaik!

First, thanks a lot for creating this super useful docker!
We use it in our CI and for some reason, it started failing since the last image update with the following error:

python: error while loading shared libraries: libpython3.9.so.1.0: cannot open shared object file: No such file or directory

We did not see any apparent changes in your latest image so we are a bit confused as too what might be happening...

Steps to reproduce:

Run docker run --rm -it --entrypoint bash nikolaik/python-nodejs:python3.9-nodejs12
Run python -> the error appears.

Hi @ericboucher 👋

I cant seem to reproduce the issue. Are you doing something special with LD_LIBRARY_PATH or similar?

Hi @nikolaik, actually we realized that the issue happened after downgrading poetry. But don't understand why that would be happening.

So to replicate, simply run the following command in the docker:

poetry self update 1.1.8
python

We found a workaround, or rather just decided to up to 1.1.11, but are curious about what could be causing the issue. And prevent it from happening again in the future :)

I'll close this for now, even though we never got to the root cause of your issue. If it pops up again in the future we can investigate further.
