设置：在 Google Cloud Shell 标准环境中运行

我尝试使用从烧瓶应用程序访问firestorefrom google.cloud import firestore

我已经使用pip install --upgrade google-cloud-firestore -t lib. 如果我手动运行脚本，它工作正常。但是在使用时dev_appserver.py，它失败了。得到下面的错误。

$ dev_appserver.py app.yaml

但是，在我的 中lib，我可以看到它们。

由于您使用dev_appserver.py它意味着您有一个标准的环境应用程序。在标准环境中，所有外部依赖项都需要安装在您的应用程序中，而不是在本地 python 安装中（这是您对pip调用所做的）。

从安装第三方库：

  1. 创建一个目录来存储您的第三方库，例如lib/.

    mkdir lib

  2. 使用带有标志的pip（版本 6 或更高版本）-t <directory>将库复制到您在上一步中创建的文件夹中。例如：

    pip install -t lib/ <library_name>
