Question

对于需要dlib的应用程序，我需要在 App Engine Standard 上安装cmake软件包。以下是安装时遇到的错误。

我尝试在Requirements.txt中添加cmake和cmake-setup，但是没有用。

请提出修复建议。

Answer 1

您可以通过自定义运行时在Flexible环境中使用非Python依赖项。来自About Custom Runtimes：

自定义运行时允许您定义新的运行时环境，可能包括其他组件，例如语言解释器或应用服务器。

另请参阅Building Custom Runtimes。

Answer 2

如果要自定义环境，可以使用容器。按照Dustin的建议将其部署在App Engine flexible上，但是请注意，App Engine Flex不会扩展为0，因此即使不使用服务也要付费。

因为您有一个容器，所以建议您看看Cloud Run。它与App Engine类似，但是缩放到0且功能非常强大。
