从python命令行调用google api时出错

Question

我对python非常陌生。我正试图通过python命令行从google cloud shell调用google监控API。我正在使用python 2.7。在此之前，我已经安装了

pip install --upgrade google-api-python-client    

这是调用google监控api的代码

from googleapiclient.discovery import build

service = build('monitoring', 'v3', cache_discovery=True)
timeseries = service.projects().timeSeries().list(
            name="my-project",
            filter="metric.type=compute.googleapis.com/instance/cpu/utilization"
            aggregation_alignmentPeriod=86400s,
            # aggregation_crossSeriesReducer=api_args["crossSeriesReducer"],
            aggregation_perSeriesAligner="ALIGN_MEAN",
            aggregation_groupByFields="metric.labels.key",
            interval_endTime="2020-08-23T17:30:04.707Z",
            interval_startTime="2020-08-22T17:30:05.603000Z",
            pageSize=100
        ).execute()

我在python命令行中传递适当的值，并在执行这一行时传递

service = build('monitoring', 'v3', cache_discovery=True)

我得到以下错误：

>>>from googleapiclient.discovery import build
>>> service = build('monitoring', 'v3', cache_discovery=True)
Traceback (most recent call last):

    project_id = app_engine.get_project_id()

    return app_identity.get_application_id()
  File "/usr/lib/google-cloud-sdk/platform/google_appengine/google/appengine/api/app_identity/app_identity.py", line 455, in get_application_id
    _, domain_name, display_app_id = _ParseFullAppId(full_app_id)
  File "/usr/lib/google-cloud-sdk/platform/google_appengine/google/appengine/api/app_identity/app_identity.py", line 436, in _ParseFullAppId
    psep = app_id.find(_PARTITION_SEPARATOR)
AttributeError: 'NoneType' object has no attribute 'find'

我不知道为什么会这样，有人能帮我吗？谢谢

我一直在我的google cloud shell上做这项工作，所以我认为这项工作不需要传递google_应用程序_凭据，就像我为其他API（如compute engine）所做的那样，但是看起来我需要从服务帐户创建一个密钥，该帐户有权通过此命令调用此监控api

gcloud iam服务帐户密钥创建iam帐户输出密钥

完成后，我必须将该值导出到GOOGLE\u应用程序\u凭证中的环境文件中
