When I check pep8 with the newest devstack env by the cmd ‘tox –e pep8’, it raise many packages conflict. The log is as follows. [...] ERROR: Cannot install oslo.messaging>=14.1.0 because these package versions have conflicting dependencies.
The conflict is caused by:
The user requested oslo.messaging>=14.1.0
The user requested (constraint) oslo-messaging===14.3.0 [...]
It's unclear from your message what version of the CPython interpreter you're using. The current releases of oslo.messaging require Python 3.8 or newer, so if you're trying to do this with older Python that would explain the error you're seeing. -- Jeremy Stanley
