The new version of Poetry 1.1.1 installs dependency parallel - but this feature broke my programm

I use websocket and websocket-client, where websocket-client extends websocket by replacin __init__.py and redefines WebSocket class, adding ssl support.

In version 1.0.0 I installed websocket -> websocket-client, but now, in CI during rpm creation, the libraries were installed as websocket-client -> websocket, and after that, rpm has the old WebSocket class without ssl support
