我有一个Python 3项目，我在Google AppEngine Standard上托管。直到几天前，我还能正常部署（就在我2019年7月做了初始设置后），直到几天前。现在我得到了以下响应。
starting build "abc"

Finished Step #0 - "fetcher"
ERROR
ERROR: build step 0 "gcr.io/cloud-builders/gcs-fetcher" failed: step exited with non-zero status: 1
任何想法为什么会发生这种情况，如何解决？
P.S.我使用以下命令进行部署。
gcloud --project my-project app deploy app.yaml
解决方案：
在与谷歌工程师交谈后(https:/issuetracker.google.comissues154588981?pli=1。)以下工作。
- 移除
source-context.json档案 - 删除部署文件所在的bucket，例如gs:/staging.my-project.appspot.com。
- 再次部署
如果你需要 source-context.json 文件，您可以按照以下步骤操作。https:/www.google.comurl?q=https:/cloud.google.comdebuggerdocssource-context&sa=D&usg=AFQjCNHMB7Dm_jISwG2AnpokQ7XN5GmLAw。
