答
原因是无法在PATH上找到gcloud SDK随附的凭证助手git-credential-gcloud.sh。
幸运的是，git不仅可以调用和检测PATH中的凭证助手，还可以在指定完整路径时接受和调用命令。
改变credential.helper来自：
credential.helper="gcloud.sh"
到：
credential.helper=/<PATH-TO-GCLOUD-SDK>/bin/git-credential-gcloud.sh
通过调用
git config credential.helper /<PATH-TO-GCLOUD-SDK>/bin/git-credential-gcloud.sh
解决的具体存储库中的问题。
