什么需要与sqlalchemy / google云sql api的google appengine一起安装?

我尝试了Can SQLAlchemy be used with Google Cloud SQL?中的建议,使用sqlalchemy建立了与google cloud sql的外部连接。

为了让google appengine软件包可以访问我的环境,在安装google appengine sdk后,我将google目录复制到site-packages并创建了一个google.pth文件,其中包含带有“./google”的单行。随后可以看到Google软件包。

当我尝试执行create_engine调用时,出现以下异常。我的安装中缺少什么?我怎么能纠正这个?

create_engine('mysql+gaerdbms:///runningdb', connect_args={"fsrcrunning":"fsrcrunningdb"})

    330     strategy = kwargs.pop('strategy', default_strategy)
    331     strategy = strategies.strategies[strategy]
--> 332     return strategy.create(*args, **kwargs)

apiclientgoogle-api-python-client的一部分,可以通过pip install google-api-python-client安装,但客户端也与lib directory中的App Engine SDK捆绑在一起,并且是副本我用。我从未将我的App Engine安装移至site-packages,而是在PYTHONPATH内添加.bash_profile的路径,就像这样(我正在运行Mac):

export PYTHONPATH=/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine:$PYTHONPATH

还有一个Google Cloud SDK,它刚刚在几周前发布,其中包含了所有Google Cloud服务,包括Cloud SQL和App Engine。
