带有firebase的cron作业-google cloud io错误

我最近刚设置了firebase函数。在完成一个简单的HeloRoWord函数工作之后,我想在下面设置一个CRON作业 Google blog tutorial 是的。 我总是在这一步出错:

gcloud app deploy app.yaml \ cron.yaml

我收到以下错误消息:

C:\Users\vreee\Firebase\functions-cron\appengine>gcloud app deploy app.yaml \ 
cron.yaml
WARNING: Automatic app detection is deprecated and will soon be removed. As 
an alternative, create an app.yaml file yourself using the directions at 
https://cloud.google.com/appengine/docs/flexible/python/configuring-your-app-with-app-yaml (App Engine Flexible Environment) or 
https://cloud.google.com/appengine/docs/standard/python/config/appref (App 
Engine Standard Environment) under the tab for your language.
Deployment to Google App Engine requires an app.yaml file. This
command will run `gcloud beta app gen-config` to generate an app.yaml
file for you in the current directory (if the current directory does
not contain an App Engine service, please answer "no").

This looks like a Python app.  If so, please enter the command to run
the app in production (enter nothing if it's not a python app): :
Writing [app.yaml] to [C:\].
ERROR: gcloud crashed (IOError): [Errno 13] Permission denied: 
u'C:\\app.yaml'

If you would like to report this issue, please run the following command:
gcloud feedback

To check gcloud for common problems, please run the following command:
gcloud info --run-diagnostics

有人知道怎么解决这个问题吗?我搜索并将自己的电子邮件地址(不是服务帐户)设置为所有者,因此应该有权限。我只是注意到它试图创建一个 app.yaml 直接在下面归档 C:\\ 而不是 functions-cron 包含一个文件夹 应用程序yaml 以及 cron.yaml 文件。

非常感谢你的帮助!!有关其他信息,我正在使用Windows..
