No package 'gobject-introspection-1.0' found while deploying to Heroku

问题

Attempted to deploy python web app to heroku but encountered the following errors:

remote:            Package gobject-introspection-1.0 was not found in the pkg-config search path.

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?

回答1:

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.
