Django到heroku的部署问题



在尝试部署我的django项目时,我遇到了一个奇怪的错误:

有一个我没有使用的依赖项,并且已经卸载,在构建期间仍然试图加载requirements.txt

我已经卸载了所有的依赖,从requirements.txt中删除了它,运行makemigrationsmigrate,但它仍然试图加载它,这导致部署崩溃。

PyGObject为依赖项。

工作流:Procfile -web: gunicorn solarsystem.wsgiran -pip3 freeze > requirements.txt卸载后,该依赖项不再显示。

然而在构建时:

Collecting PyGObject

这是我的requirements.txt:

我已经尝试了requirements.txtProcfile配置的多种变体,查看了我的源代码中PyGObjectgi的任何导入,并且没有。我还搜索了PyGObject文档和其他堆栈溢出资源,但没有成功。

重申一下,我想以某种方式完全删除它,或者以某种方式为该依赖项添加一个ignore语句,以便我可以成功部署。

matplotlib使用PyGobject,这就是为什么当你安装require .txt文件时,它会尝试安装PyGobject。https://pygobject.readthedocs.io/en/latest/尝试使用以下命令。它可能会解决安装PyGobject

的问题。
python3 -m pip install --no-use-pep517  cm-rgb

sudo pacman -S python cairo pkgconf gobject-introspection gtk3 
pip3 install pycairo to build and install Pycairo
pip3 install PyGObject to build and install PyGObject
