Order of locked package markers is unstable. #1457
Description
-
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 (
-vvvoption). -
OS version and name: macOS
-
Poetry version: 1.0.0b1
-

Issue
When performing a poetry update package markers in poetry.lock get re-ordered in an unstable way. For example, running poetry update on the provided pyproject.toml keeps swapping these markers around in the poetry.lock file.
