我有一堆小的Raspberry Pis运行一些python代码，使用gcloud-python数据存储包直接保存到Datastore（跳过GAE）。这非常有效。我现在想要使用Google App Engine通过网络和移动客户端呈现数据。在我的MacBook上，我使用安装程序安装了GAE，通过pip安装了gcloud。我可以编写一个简单的python脚本并直接从终端执行它，它可以通过gcloud从数据存储区写入和读取 - 这也可以正常工作。
然而，当我尝试将相同的代码合并到GAE中时，它失败了。根据我的研究，我预计这是一个PATH问题，但经过几个小时的各种尝试后，我无法解决这个问题。建议将不胜感激。
我认为这篇文章与我的问题类似：Google App Engine, Change which python version
以下是一些可能相关的信息：
Python版
$ which python
/usr/bin/python
根据引用的Stack Overflow问题，我将GAE的首选项设置为Python路径为/ usr / bin / python。我试过了

您可以在App Engine上运行gcloud-python，但它需要一个
额外的工作。看看我写的骨架project
这使得这个工作。
要涵盖的主要基础是：
在install_gcloud.sh中，pip用于安装gcloud及其pip install --target="application/vendor/" gcloud
使用
pip（如other answer中所述，本地安装不会上传 在部署时使用App Engine。）
按--target - 安装pkg_resources.get_distribution集，pytz
将按预期工作（它在堆栈跟踪中失败）。
此外，默认情况下pytz有太多的读取才能正常工作
App Engine，因此使用gae-pytz。结果，一些oauth2client.client
需要修改进口。
此外，为了减少计算引擎检查开销（网络开销），
vendor/模块可以修改。
这两项调整都可以在一个commit中找到。
上面的脚本将所有依赖项放在名为import darth
darth.vendor('vendor')
和的目录中
appengine_config.py将此添加到导入路径中
Darth Vendor：
protobuf此外，由于google依赖也是其中的一部分
google.appengine.ext.ndb包（就像所有App Engine导入一样，例如
__path__）您需要修改import os
import google
curr_dir = os.path.abspath(os.path.dirname(__file__))
vendor_dir = os.path.join(curr_dir, 'vendor')
google.__path__.append(os.path.join(vendor_dir, 'google'))
与该包相关联：
gcloud-python请注意在App Engine中使用db
比使用本机App Engine库ndb或gcloud-python慢3-5倍。
这是因为那些使用直接RPC到App Engine运行时
{{1}}将使用App Engine外部的HTTP与云进行通信
数据存储API。
注意：我在最初发布后更新了这个，引用了 历史上的前一个point。

Mac上的GAE无法访问Mac上默认位置安装的Python软件包。你需要这样做：
ln -s /Library/Python/2.7/site-packages/.../gcloud /Users/sheridangray/Projects/city-pulse-web/gcloud
（需要用相关路径信息替换...）
