python - Google App Engine rtree Python 模块安装

问题描述

Google App Engine，不包括 libspatialindex，因此我无法安装 rtree python 模块，即使它在 requirements.txt 中，

它在部署应用程序时出现以下错误。（应用程序在本地运行良好。）如何在 python 标准谷歌应用程序引擎环境中安装特定的库？或者我如何要求他们这样做？

解决方案

您将需要使用具有自定义运行时的灵活环境来利用标准环境中未预安装的软件包。

要安装 libspatialindex，请将其添加到 Dockerfile：

sudo apt-get update -y
sudo apt-get install -y libspatialindex-dev
