python - GAE : remote_api and Application Default Credentials

Question

从今天开始，我一直在使用 remote_api (python) 访问 GAE 上的数据存储。

我通常做remote_api_shell.py -s <mydomain> .

今天试了一下，还是失败了，错误是:

oauth2client.client.ApplicationDefaultCredentialsError: The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials. See https://developers.google.com/accounts/docs/application-default-credentials for more information.

我不明白为什么它会问我。

整个输出是这样的

解决办法是在shell中运行gcloud auth login，重新给grant
