Poetry very slow with some packages since 1.2

Hello,

Since updating to Poetry 1.2.X dependency resolution is very slow for some packages. (After uninstalling 1.2.2 and installing 1.1.15 everything is working fine).

I’ve tried clearing caches. It seems to always block at Creating new session for files.pythonhosted.org.

Exemple with numpy: (using poetry run pip install numpy works fine)

$ poetry init
$ poetry add numpy -vvv

→ hangs for a very long time

mostly this symptom is because of a stray .lock file in your cache and will be resolved by find ~/.cache/pypoetry/ -name '*.lock' -delete or equivalent if your cache is somewhere else.

this is fixed in 1.3

I confirm that Poetry 1.2.2 sometimes may hang forever for poetry lock on Python 3.10.6.

I was waiting for a few hours. Then I enabled verbosity and I saw that Poetry hangs right after Creating new session for (GitLab in my case). Poetry gets 200 response status code and hangs forever. Nothing happens further.

The solution is to run sudo rm -r ~/.cache/pypoetry
