Just for a little troubleshooting.
Did you run ollama serve first? It will run the daemon that you will need for the commands like ollama run and ollama pull

You can read about the diverse commands with ollama --help

I can elaborate more if needed.

OLLAMA_HOST is malformed. You have it set to ''0.0.0.0：8157:11434" where the first colon is unicode character FULLWIDTH COLON. ollama splits at the ASCII colon to get host and port, and the host is ' 0.0.0.0：8157' and the port is 11434. ' 0.0.0.0：8157' it not a resolvable hostname so the lookup fails.

Thanks @rick-github - @hdsnzsr let us know if this still doesn't fix it.
