• 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 (-vvv option).

• OS version and name: windows 10
• Poetry version: 1.2.0a2

Issue

it would be nice if there was some sort of output other than just the exit code

> poetry lock --check

> echo %errorlevel%
1

perhaps an error message like

Error: poetry.lock is out of date. run `poetry update` to fix it
