Couchdb 2.3.1 python Views

[Victor CORREIA]

Hi couchdb Users.

I used couchdb and i was upgraded couchdb from 2.2.1 to 2.3.1 , but pb
my python views don't works.

I have try to change like doc , but no success.

export COUCHDB_QUERY_SERVER_PYTHON="/path/to/python/query/server.py with args"

I tried;
I have install python3.
export COUCHDB_QUERY_SERVER_PYTHON="/usr/bin/python3 /usr/bin/couchpy"

but i have Error running query. Reason: (unknown_query_language)
python, on Fauxton when i try  my custom views.

do you have an example or more information to resolv my problem  ?

thanks..

Victor.
