OS = Ubuntu 18.04(Bionic)
Python 3.7.1
In requirements.txt:
pycairo==1.18.0
PyGObject==3.30.2
I've installed libgirepository1.0-dev as below;
$ whereis gobject-introspection-1.0
gobject-introspection-1: /usr/include/gobject-introspection-1.0 /usr/share/gobject-introspection-1.
But I still see the same error above. Are there any other applications that I need to install on Ubuntu to fulfill the dependency?
After manually editing requirement.txt files with content below;
Flask
gunicorn
Heroku was able to accept my git push. I've learned to only use the required dependencies in requirement.txt. Thanks Chris for point me to the right direction.

I'm simply trying to push my Flask app to Heroku but I encountered the following error:

I'm not sure what I need to do to get rid of this error.
The error message says it all:
xlwings requires an installation of Excel and therefore only works on Windows and macOS. To enable the installation on Linux nevertheless, do: export INSTALL_ON_LINUX=1; pip install xlwings
You might be using a package in your app named xlwings which is built to be used on Windows and Mac but the servers on Heroku have linux installed on them so you'll first have to set an environment variable INSTALL_ON_LINUX to 1 then try to deploy the app again.
From the Heroku CLI you can do:
heroku config:set INSTALL_ON_LINUX=1
I'm having issues deploying my bot i made using discord.py into discord using heroku. I've followed many guides and looked into mane other sources as well to why it is happening and nothing seems to be working. This is what i get....

Does anyone know why this is happening?
This is through the command prompt btw!
You've declared https://github.com/tony1bally/education-helper as a dependency in requirements.txt but the repository is empty and cannot be installed with pip as a Python module.
Remove it from requirements.txt, add, commit and push again.
I'm trying to use the playsound module in a very simple Django app with the below code which plays an mp3 file:
from playsound import playsound
playsound(filename)
However, my push to Heroku fails at PyOBjC (which is apparently also needed). I've pip installed playsound and PyObjC (without PyObjC, my play fails for needing AppKit). With both modules installed, the application works great on my local server.
It all works great until the Heroku build. Snippet of the error below. Does anyone have any ideas for what I need to do to get this build to work?

The playsound module only has a dependency on PyObjC when used on macOS, for Linux machines (such as Heroku) the library has a dependency on "PyGObject" and the GStreamer library.
Note that playsound plays the sound on the machine that's running the code, which is probably not what you want when you use Heroku (it will try to play the sound a machine at Heroku).

You can try to reach your slug with heroku run bash --app appname and then try to install libgirepository1.0-dev. In case of failure, use heroku-community/apt, more info at heroku-buildpack-apt
I've been trying to install certain python packages to my Django Web App on Azure. I'm trying to install the packages using the requirements.txt and pips wheel files, as is instructed here https://blogs.msdn.microsoft.com/azureossds/2015/06/29/install-native-python-modules-on-azure-web-apps-api-apps/
The problem is that pip does not seem to locate the wheelhouse folder. The wheelhouse folder is located at the root of my app directory, where I'm also keeping the requirements.txt, manage.py, readme.md and the web.config files.
Here's what my requirements.txt file looks like:
--find-links wheelhouse
django<2
pyodbc==4.0.17
django-pyodbc-azure==1.11.0
Here're the files in wheelhouse folder:
~/myapp/wheelhouse/django_pyodbc_azure-1.11.0.0-py2.py3-none-any.whl
~/myapp/wheelhouse/Django-1.11.4-py2.py3-none-any.whl
~/myapp/wheelhouse/pyodbc-4.0.17-cp27-cp27m-win_amd64.whl
~/myapp/wheelhouse/pyodbc-4.0.17-cp27-cp27m-win32.whl
I've downloaded the pyodbc .whl files from here:http://www.lfd.uci.edu/~gohlke/pythonlibs/
The django_pyodbc_azure-1.11.0.0-py2.py3-none-any.whl file was created by using a windows laptop with the windows c++ compiler for python installed (https://www.microsoft.com/en-us/download/confirmation.aspx?id=44266)

I'm really confused as to what I'm doing wrong here. Any ideas? One guess would be that the wheelhouse folder should be move to a subdirectory? I tried to move it to the app env folder under scripts, but it didn't work either.
Thanks for your time.
EDIT
So I tried to run the scripts straight from my Kudu console and here's the error I'm getting:
D:\home\site\wwwroot\env\Scripts\pip run on 08/25/17 15:51:48

The recommended approach is to update Python on your WebApp using an extension:
https://learn.microsoft.com/visualstudio/python/managing-python-on-azure-app-service
Since actually, the default version of Python on WebApp are terribly old (and unsecure). You will get a newer version of pip, able to deal with all wheel files (currently it's not as you saw...).
Note that the Python extension are compiled by Microsoft, they are official.
