Question

connection from digitalocean function using python to postgresql won't work

I have been playing around for quite some time now following the given instruction. I have a requirements.txt and psycopg2-binary inside, and I am able to build with build.sh. But the function initialization always fails complaining :

"logs":**[**_1 item_
0:
"2024-06-16T23:59:50.742228781Z stderr: Invalid function: No module named 'psycopg2._psycopg'"

**]**

Does anyone have a successful experience? Please help if yes, thanks!

Hi there,

Do you have the psycopg2 package defined in your requirements.txt file?

Also can you share your function structure here along with the content of your build.sh file?

Here is an example of a build.sh file that should work:

#!/bin/bash

set -e

virtualenv --without-pip virtualenv
pip install -r requirements.txt --target virtualenv/lib/python3.9/site-packages

It should be located in your function directory itself, eg. /packages/your-func-name/your-func-name/build.sh.

Here is an example Python function that has a good example of a build.sh file with a requirements.txt file that you could use as a blue print:

Let me know how it goes!
