Pipenv: "Loading .env environment variables" logs to stderr

[caspervdw]

This is a minor annoyance, as in some scripts we log stderr.
I think this should be changed, as it is not an error message.

Thanks in advance!

Hey, thanks for the input! I agree it isn’t an error, but we actually log most things to stderr for various reasons. If we redo this it will be part of a broad restructuring, i would be very hesitant to change where we send messages haphazardly. Thanks again though!

Maybe it’d be reasonable to add an environ (PIPENV_QUIET) or something to suppress some of the informational messages we produce. This, the “installing initially failing packages”, the “ignoring marker”, and probably some else.

I think we have an env var and we just don't really use it much. We should flag this as a tracking item in a cleanup project

@techalchemy apologies for replying in a closed issue but I didn't want to open a dupe to add my thoughts.

I currently use pipenv run in several cron jobs and this creates a situation where I have to send all output to /dev/null or I get an email with Loading .env environment variables… on each run. I'm running the risk of not seeing real error output because I can't silence this message. I'd be all for a -q quiet flag or PIPENV_QUIET to handle this case.

Your last comment seems to indicate that you meant to re-open this. Maybe?

The PIPENV_QUIET environment variable has since been implemented, but it is not applied to run yet. Feel free to work on this.

@uranusjr I'm surprised to read that it has been implemented. As of version 2018.11.26 it doesn't appear in the list shown by pipenv --envs or listed in the docs.

I'll take a look at the code and try to implement it.

I proposed a fix in #3457, if someone wants to reconsider this issue and review the PR. I think this issue is important for pipenv adoption, as properly using _pipenv run_ commands in cron may be a frequent use case.
