Mailing List Archive: Pip standard error warning about dependency resolver

I understand your problem and I know that sometimes it is not possible
to do it differently. But as far as my understanding goes, your backend
operations should not die on outputs on stderr. I understand that is
what return values are for and as long as the return value is 0
everything went without error, even though there might be output on stderr.

That said. As far as I know you could try the commandline option for
using the new resolver explicitly. I don't know if there is an option
for "silent"

Cheers

Lars
