I try to install umap on an alwaysdata server.

I follow this tutorial : https://umap-project.readthedocs.io/en/latest/install/

At the migrate step

umap migrate

i have this error:

}

The alwaysdata team haven't find a solution for my problem. https://forum.alwaysdata.com/viewtopic.php?id=4763

Have you any idea?

Thanks a lot.

The last three lines of the error message are pretty clear, aren' they? It's expecting to connect to Postgres via a named pipe at /var/run/postgresql/.s.PGSQL.5432, but that file doesn't exist. Does anything named similarly exist in /var/run/postgresql/? Can you see the server running when you type "ps aux | grep postgres"? It looks like umap (which I don't have a clue about, sorry) is actually supposed to use an IP socket to connect but somehow the database adapter is forced to only try the Unix socket. Maybe psycopg2 has some kind of config file?

Thanks a lot for your answer. I'm sorry for the delay.

The folder /var/run/postgresql/ doesn't exist. "ps aux | grep postgres" return nothing

I haven't find any psycopg2 config file. From psycopg2/__init_.py def connect(dsn=None,
database=None, user=None, password=None, host=None, port=None,
connection_factory=None, cursor_factory=None, async=False, **kwargs):

the inputs values are:

user : None password : None database : **** # not the good one host : None

I have force the values inside this init.py file:

The output error is : django.db.utils.OperationalError: could not translate host name "postgresql−****.alwaysdata.net" to address: Name or service not known
