依赖项未从 google 应用引擎中的 lib 目录安装

Question

据我所知，我已经正确设置了我的 Flask 应用程序。包含所有依赖项的 lib 位于我的根目录，并包含 Requirements.txt 中的内容。我的 appengine_config.py 包含以下内容

print 'running app  config yaya!'

from google.appengine.ext import vendor
import os
import sys


print os.path
print os.path.realpath
print os.path.realpath(__file__)

print os.path.join(os.path.dirname(os.path.realpath(__file__)), 'lib')

sys.path.insert(0,'./lib')
vendor.add('lib')
print 'I am the line after adding lib, it should have worked'

根据所有这些打印语句，没有任何错误，但我得到了

No module named flask_sqlalchemy

在部署并看到 500 后。我缺少什么来安装这些吸盘？

不确定是否相关，但我也收到 https://code.google.com/p/google-cloud-sdk/issues/detail?id=729 但这个修复没有帮助

---更多编辑

我将所有内容从 /site_pakcages 向上移动到 /lib 目录，我离得更近了，我的一些页面甚至可以正常工作！但现在我得到

ImportError: No module named _sqlite3

但代码显示为

except ImportError as e:
try:
from sqlite3 import dbapi2 as sqlite # try 2.5+ stdlib name.
except ImportError as ee:
raise ee
return sqlite

为什么这里的导入尝试会有下划线？有帮助吗？

tldr：使用 appengine_config.py 并将您的 virtualenv 复制到名为 lib 的文件夹，然后确保您正在通过 dev_appserver.py

运行安装应用程序

（下面是通过bash in ubuntu）所以经过长时间的战斗，我发现虚拟环境和gcloud 玩得不好-

我从我的虚拟环境目录中复制了所有内容

.../.virtualenvs/nimble/local/lib/python2.7/站点包

进入

[项目目录]/lib

和我的 appengine_config.py 终于像在云中一样在本地工作了，但我绝对必须运行

dev_appserver.py [my proj dir here]

或 google.appengine 模块无法加载。不知道我应该使用开发服务器。我觉得很傻。

供参考，这里是appengine_config.py

"""`appengine_config` gets loaded when starting a new application instance."""

print 'running app  config yaya!'

from google.appengine.ext import vendor
vendor.add('lib')
print 'I am the line after adding lib, it should have worked'
import os
print os.getcwd()
