I have been following the documentation until I got to the point of installing the requirements.txt file. It always fails when trying to install line 6 "psycopg2==2.5.3". Here is the message -

Of course I found several posts on this. So I started checking things. I believe that postgres app for mac comes with psycopg2. I do have postgres added to my path and checked in terminal running "echo $PATH". I do not have any other old versions conflicting. And postgres documentation says I should have it added to my path like this -
export PATH="/Applications/Postgres.app/Contents/Versions/9.3/bin:$PATH:$PATH"
I have restarted postgres app, deactivated and restarted virtual env and I get the same error no matter what.
What could I possibly be overlooking! I have read and read other posts on here, and even blogs covering this issue.
After reading dozens of the same errors people were all having with the postgres mac app. I decided to install postgres via brew and now it all works just fine.

After I enter all the private details into streamlit to connect to the Postgresql database, I cant seem to figure out how to get the Package Psycopg2 to import correctly on the Streamlit cloud.
When Streamlit tries to download the Psycopg2 package, the following error arises:

My problem is that I don't know how to add pg_config to the PATH. Here is my github: https://github.com/zuhorski/My-UFC-Project
Also for what its worth, I'm working in a virtual environment and I did find where this pg_config file is located: "C:\Program Files\PostgreSQL\15\bin"

As far as I've seen, for production, you shouldn't use psycopg2-binary, but then psycopg2 doesn't give me many options.
The Cpanel has PostgreSQL installed, and it even has phpPgAdmin. I tried seeing a lot of videos and questions done here on this platform but haven't found anything.
Any solution to this?
Complete newbie here, trying to set up Django to work with PostgreSQL.

I know that directory containing pg_config is /opt/PostgreSQL/9.5/bin/pg_config but I don't know how to add this directory to PATH to get my psycopg2 installed. Or any another method to get psycopg2 installed so that I can interact with my PostgreSQL.
Thanking you in advance.
Unless you do have a hard requirement on using the native postgresql library, I would advise you to use the pg8000 library instead because this one is pure python.
Since I discovered it years ago, I stopped using the other one and forgot about the having to compile it on so many platforms.
Hoping you can help me figure this one out. I'm slogging through the Heroku 'Getting Started with Python' page where you install the necessary dependencies to run an app locally. It all works well up until the 2nd to last step, running the command virtualenv venv. I run that, then the next command, pip install -r requirements.txt --allow-all-external, and that's where I get this error:
Error: pg_config executable not found.
Please add the directory containing pg_config to the PATH
or specify the full executable path with the option:
python setup.py build_ext --pg-config /path/to/pg_config build ...

I don't understand why I'm getting this error. Can anyone help me make sense of it?
My version of requirements.txt:
dj-database-url==0.3.0
Django==1.8.1
django-postgrespool==0.3.0
gunicorn==19.3.0
psycopg2==2.6
SQLAlchemy==1.0.4
whitenoise==1.0.6
pg_config is part of postgresql ( http://www.postgresql.org/docs/8.1/static/app-pgconfig.html ).
So you need to install postgresql.
brew install postgresql

I have overcame this issue defining a environment variable HEROKU and putting the following lines at the end of settings.py
if config('HEROKU', cast=bool, default=False):
import django_heroku
django_heroku.settings(locals())
As Heroku use the buildpack: heroku/python, there is no additional configuration to perform
I'm trying to build a Python package for this project that includes the .json files in /fixtures and the *.html files in /templates. When I run the packaging script based off my setup.py, it says it should include those folders in the MANIFEST it generates, but the output just says it's hard-linking them and when I try to install via pip, it dies on the following:

EDIT: It looks like this was an issue with legacy crud that built up in the virtualenv I was installing succeeding versions of the package into. Trying a clean virtualenv fixed the issue.
Fixed this issue by creating a clean virtualenv and trying to build from there. It appears the constant build/ rebuild cycle in the original environment left legacy files behind that were stopping things from working as intended.
