我在 AppEngine Python 3.7 Standard 中有一个简单的设置,只有两个文件:requirements.txtapp.yaml

requirements.txt 文件是:

Flask==1.0.2
python3-saml==1.4.1

app.yaml 文件是:

runtime: python37
service: myservice

当我运行 gcloud app deploy 时,出现以下错误:

ERROR: (gcloud.app.deploy) Error Response: [9] Cloud build f8eaa62c-0385-4c1a-9788-b7765313ae08 status: FAILURE.
Build error details: {"message": "`pip_download_wheels` had stderr output:\n Failed building wheel for xmlsec\nERROR: Failed to build one or more wheels\n\nerror: `pip_download_wheels` returned code: 1", "code": 1, "type": "USER_ERROR"}.

关于如何解决这个问题有什么想法吗?

提前谢谢你。

最佳答案

python3-saml 包依赖于 xmlsec ,这实际上是导致此处构建失败的原因。 This package has pre-install dependencies on system-level libraries ,因此日志中有这条消息:

Could not find xmlsec1 config. Are libxmlsec1-dev and pkg-config installed?

无法在 AppEngine 标准环境中安装这些系统级包,相反您需要使用 a custom runtime with AppEngine Flex ,或使用不依赖于系统级包的 python3-saml 的替代品。
