烧瓶应用引擎不能与firestore一起使用？

Question

设置：在谷歌云壳牌标准信封

来看，我试图从它使用pip install --upgrade google-cloud-firestore -t lib使用from google.cloud import firestore

我已经安装了瓶的应用程序访问公司的FireStore。如果我手动运行脚本，它工作正常。但是当使用dev_appserver.py时，它会失败。有下面的错误。

$ dev_appserver.py app.yaml

但是，在我的lib中，我可以看到它们。

Answer 1

由于您使用的是dev_appserver.py，这意味着您有一个标准的env应用程序。并且在标准env中，所有外部依赖需要在您的应用中安装，而不是在本地python安装（这是您对pip调用所做的）。

从Installing a third-party library：

1. 创建一个目录来存储您的第三方库，如lib/。

   mkdir lib 
   

2. 使用pip与-t <directory>标志（6或更高版本）的库复制到您在上一步 创建的文件夹。例如：

   pip install -t lib/ <library_name>
