在部署到Heroku时找不到包'gobject-introspection-1.0‘

Question

尝试将python web应用部署到heroku，但遇到以下错误：

remote:            running build_ext
remote:            Package gobject-introspection-1.0 was not found in the pkg-config search path.
remote:            Perhaps you should add the directory containing `gobject-introspection-1.0.pc'
remote:            to the PKG_CONFIG_PATH environment variable
remote:            No package 'gobject-introspection-1.0' found
remote:            Command '('pkg-config', '--print-errors', '--exists', 'gobject-introspection-1.0 >= 1.46.0')' returned non-zero exit status 1.
remote:            
remote:            Try installing it with: 'sudo apt install libgirepository1.0-dev'
remote:

OS = Ubuntu 18.04(仿生) Python 3.7.1

在requirements.txt中：

pycairo==1.18.0 PyGObject==3.30.2

我已经安装了libgirepository1.0-dev，如下；

$ whereis gobject-introspection-1.0
gobject-introspection-1: /usr/include/gobject-introspection-1.0 /usr/share/gobject-introspection-1.

但我仍然看到上面的错误。我还需要在Ubuntu上安装其他应用程序来满足这种依赖吗？

Answer 1

手动编辑包含以下内容的requirement.txt文件后；

Flask
gunicorn

Heroku能够接受我的git推送。我学会了在requirement.txt中只使用所需的依赖项。谢谢Chris为我指明了正确的方向。
