python - 部署到 gcp 应用引擎后无法连接到云存储

问题描述

我正在 App Engine 虚拟机上开发一个 Flask 应用程序。我想将文件上传到谷歌云存储，所以我storage_client = storage.Client()用来连接到云存储。单独在 VM 中测试时，我的应用程序运行良好，没有错误。但是，在我部署gcloud app deploy并在我部署的应用程序上测试上传功能后，它失败并返回Internet 500错误。日志显示了回溯，这是由于连接到云存储的代码行：storage_client = storage.Client()

具体报错__init__() takes 2 positional arguments but 3 were given见云存储库函数。我有这个应用程序的python 3.5，我真的不知道如何解决这个问题。任何帮助将非常感激！

下面是我的“requirements.txt”：

Flask==1.0.2
gunicorn==19.9.0
firebase-admin==2.13.0
google-cloud-firestore==0.29.0
google-cloud-storage==1.17.0
lxml==3.7.3

标签： pythonpython-3.xgoogle-app-enginegoogle-cloud-platformgoogle-cloud-storage

解决方案

您正在使用旧库。更新您的 requirements.txt 以使用当前版本。

例如：

您正在使用google-cloud-firestore==0.29.0，但当前版本是google-cloud-firestore==1.3.0

您的大多数模块都已过时，并且在某些情况下不兼容（以及与当前库的古老库）。
