问题在于，每次我在Google云端中部署我的应用程序时，都会抛出一个错误以阻止部署。我正在尝试找出错误并说AttributeError: 'Blueprint' object has no attribute 'teardown_appcontext'。我试图找到一个解决这个问题的方法，也许有人也遇到了这个问题，但是我的独特之处是没人遇到过这个问题。但是它可以在本地主机上工作。
这是错误：
Updating service [default] (this may take several minutes)...failed.

Flask-Minify
这是用于部署我的应用的app.yaml：

答案 0 :(得分：0)
由于我看不到您的class Alert: UIAlertController {
}
let alert = Alert(title: "Title", message: nil, preferredStyle: .alert)
alert.message = "Message"
模块内部的内容，因此我无法重现与您相同的错误。但是请注意，Python3 runtime for App Engine Flexible在某些方面与您的本地环境有所不同，包括pre-installed system packages。
我的建议是，您在Docker容器中运行此应用程序以模拟您的本地环境设置，并在其工作时将Docker映像部署到Cloud Run。为此，您可以激发this tutorial的灵感。
