App Engine部署:凭证文件不可写....以只读模式打开....任何刷新的凭据仅对此次运行有效

Question

我最近升级了我的云SDK,现在我再也无法灵活地部署到app引擎了.我使用以下命令部署我的应用程序:

C:\Program Files (x86)\Google\Cloud SDK\google-cloud-sdk\bin\gcloud.cmd preview app deploy --promote vm.yaml

我得到以下输出和崩溃(删节):

WARNING: Could not acquire lock C:\Users\Michael\AppData\Roaming\gcloud\credentials.lock in 0 seconds
WARNING: The credentials file (C:\Users\Michael\AppData\Roaming\gcloud\credentials) is not writable. Opening in read-only mode. Any refreshed credentials will only be valid for this run.

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

以下是一些输出 gcloud feedback

这是2016年6月推出的Google SDK并行上传功能的错误.通过使用以下命令关闭该功能来解决该问题:

gcloud config set app/num_file_upload_processes 1

上面的命令将并行上传的数量限制为1个线程/进程,因此它们不会互相踩到彼此的脚.
