我想将本地灯具数据下载到csv中,以确保其安全。
我在6个月前尝试过something similar,唯一不同的是我从已部署的appengine项目下载数据,而不是从本地数据存储区下载。
但是,如何从本地数据存储区下载它?
appcfg.py download_data --url=http://localhost:8080/_ah/remote_api/ --filename=data.csv --email=x@w.eu --application="dev~myApp"
我收到以下错误消息:

知道我做错了吗?
答案 0 :(得分:1)
发生此错误是因为dev app引擎不会自动生成数据存储区统计信息。相反,您必须执行上述步骤以手动生成这些统计信息。
