Question

这是我尝试使用gcloud app deploy进行部署时收到的错误。我以前成功部署了相同的应用程序。我能够在本地计算机上运行该应用程序，但在部署

时收到错误

tl; dr：将您的google-cloud升级到0.27，它应该解决问题。

我认为这是新google-cloud依赖项的错误。在我的情况下，google-cloud==0.25在其setup.py：

中引入了这些依赖项

 'google-cloud-core >= 0.24.0, < 0.25dev',
 'google-cloud-datastore >= 1.0.0, < 2.0dev',

就在最近的8月24日（提交此问题的前一天），google-cloud-datastore包已更新为1.3.0。

不幸的是，google-cloud-datastore 1.3.0取决于较新版本的google-cloud-core：

 'google-cloud-core >= 0.27.0, < 0.28dev',

但似乎这个版本冲突没有得到解决/未经过使用旧版本的pip警告。但google-cloud-datastore想要from google.api.core import page_iterator，即使是google.api.core，但在0.27.0之前未添加，然后一切都会中断。

我认为“bug”在google-cloud===0.25（或者你正在使用的任何版本）的过载广泛依赖中。

我认为我们的“修复”是升级到最新版本的google-cloud=0.27。

虽然google-cloud的“正确修复”是为了改善其版本依赖性，而不是那么广泛，或者冒着与已发布模块向后兼容的风险。
