无法在 Raspberry Pi 3 中使用 Python3.6 安装 PyGObject

Question

我在 Raspberry Pi3 中手动安装了 Python3.6。我正在尝试安装 PyGObject，但失败并出现错误：

据我了解，构建 PyCairo-1.20.0 时发生故障，需要 cairo >= 1.15.10' 但 cairo 的版本是 1.14.8。

可能的解决方案：

pycairo-1.20.0 是最近发布的版本（2020 年 10 月 5 日）。如果构建使用 pycairo-1.19.1，我相信安装会成功，因为它需要 cairo >= 1.13.1.

所以，我的问题是：

忽略我的“可能的解决方案”，有什么方法可以使用 pip3 安装 PyGObject for python3.6 in Raspberry Pi 3？
关于我的“可能的解决方案”，如何安装使用 PyCairo-1.19.1 的 PyGObject？

Answer 1

我执行的命令是：

sudo PYGOBJECT_WITHOUT_PYCAIRO=1 pip3 install --no-build-isolation --no-use-pep517 pygobject

在不安装 PyCairo 的情况下安装 PyGObject。
