Ada Wong commented on FLINK-25418:
----------------------------------
cc [~dianfu] I want to fix this. I will add the '--no-index' option in
PythonEnvironmentManagerUtils#pipInstallRequirements method, when the
requirementsCacheDir is not null.
When we set '--no-index', it will only install with offline, never download
from the internet.
When we do not set '--no-index', it will first download from the internet, and
then install with offline.
> The dir_cache is specified in the flick task. When there is no network, you
> will still download the python third-party library
